Victron Energy GX IO-Extender 150 Ingresso e uscita migliorati per dispositivi GX

Introduzione
GX IO-Extender 150 è un modulo di espansione collegato tramite USB che estende le porte IO disponibili dei dispositivi GX, come Ekrano GX e Cerbo GX.
Colma il divario tra il tuo dispositivo GX e il mondo esterno, creando infinite possibilità di monitoraggio, controllo e automazione.

Caratteristiche

• 8 digital IOs, configurable as in two sets of four as inputs or outputs (via DIP switch).
• 4 PWM ports, 0 to 5V with 0.04V steps for device regulation.
• 2 latching relays that maintain their state even if the power is lost.
• 1 solid switch with bat-, load, and bat+ connections for switching requirements.

The plug-and-play USB connectivity makes installation effortless. The GX IO-Extender 150 is simply plugged into an available USB port on the GX device and the inputs/outputs, PWMs and relays immediately become available to the system.
Whether you’re managing a complex off-grid solar installation, a marine electrical system, or an industrial backup power solution, the GX IO-Extender 150 expands your ability to deliver on specific requirements:

• Monitor additional sensors and equipment
• Control external devices with precision
• Automate complex system responses
• Implement sophisticated control logic

The GX IO-Extender is not intended to be used for general load switching, but rather for signalling. The relays and solid switch have low current ratings that vary based on the voltage in uso. Prodotti compatibili come quelli di Energy Solutions (Regno Unito), Garmin (Stati Uniti) e Safiery, e altri, saranno più adatti per applicazioni di commutazione generali.

Installazione

The GX IO-Extender 150 works with all GX devices but it is best used in combination with Node-RED. Node-RED is not supported on all GX devices. Refer to the Venus OS Large documentation for more information about which GX devices support Node-RED.
To install the GX IO-Extender 150:

1. Use the DIP switches on each bank of 4 digital I/Os to set them as 4 inputs or 4 outputs (ON = output, OFF = input). Note that changes to the DIP switches require a power cycle of the device.
2. Connect the USB cable of the GX IO-Extender 150 to an available port on the GX device. Note that the USB-port closest to the HDMI port on some Cerbo GX models may not be suitable for this purpose. Please refer to the GX device manual for more information.
3. Confirm the GX IO-Extender 150 is powered via the USB connection.
4. Utilizzare la console remota sul GX per riview i relè aggiuntivi, i PWM e gli ingressi o le uscite digitali disponibili sul sistema.

Hardware
Tutte le porte del GX IO-Extender 150 sono dotate di LED blu o arancioni per indicarne lo stato attuale.

Le uscite digitali sono destinate esclusivamente alla segnalazione e non devono essere utilizzate per commutare direttamente i carichi. Le uscite PWM sono adatte ad applicazioni come la regolazione della luminosità dei LED, il controllo della velocità dei motori e applicazioni simili.

Nota tecnica: Always check the maximum ratings for each output type in the datasheet of the GX IO-Extender 150.

I/O digitale
The digital I/O ports are split up in 2 groups of 4 ports which are intended for signalling rather than directly switching loads. Each group can be configured as either input or output using the dip switches in between the ports.

• Mode ON = output
• Mode OFF = input

Dopo aver modificato la modalità, riavviare il GX oppure scollegare e ricollegare il cavo USB per riavviare il dispositivo e rendere effettive le modifiche.
Nota tecnica: The digital outputs can source 4 mA max. When driving 4 mA, the voltage drop across the internal series resistor (560 Ω) is 2,24 V, which leaves only 2,76 V @ 4 mA for the output signal. Therefore, a driver like a transistor or FET is required to switch a relay with a digital output.

Movimentazione continua
The PWM ports are to be connected between GND and signal. The PWM port indicator LEDs are illuminated when the port is switched on, and the intensity of the illumination reflects the current status of the PWM slider value.

Bistable Relays (Relay 1 & 2)
The bistable (latching) relays on the GX IO-Extender 150 work differently from the monostable (non-latching) relays found on devices like the Cerbo GX.
A monostable relay has a default state determined by its wiring:

• NO (Normally Open): Load is OFF by default, ON when relay is powered.
• NC (Normally Closed): Load is ON by default, OFF when relay is powered.

A bistable relay has two stable positions — A and B — that stay fixed even when power is lost. The relay switches between them with a short pulse, using no power to maintain either state. The active position is shown by the LED:

• Blue LED: Position A active
• Orange LED: Position B active

Comune esamples

1. Mimicking a NO monostable relay
   To replicate the behaviour of a normally open relay:
   • Connect your power source to COM.
   • Connect your load to Terminal A.
   • Leave Terminal B disconnected.
   • Configure the relay in Toggle mode.
     In position A (blue LED), the load is powered. In position B (orange LED), the load is disconnected.
     Se il carico deve essere spento dopo un ciclo di accensione/spegnimento, impostare il relè in posizione B prima dello spegnimento.
2. Switching between “GREEN” and “RED” indicator lights The relay can switch power between two circuits, for exampon:
   • COM connected to your power source.
   • Terminal A wired to an “GREEN” indicator light.
   • Terminal B wired to an “RED” indicator light.
   • Configure the relay in Toggle mode.
     In posizione A (LED blu), la luce VERDE è attiva. In posizione B (LED arancione), la luce ROSSA è attiva.
3. Momentary operation: Siren and “All OK” light For momentary operation with default feedback:
   • COM connected to your power source.
   • Terminal A wired to a siren.
   • Terminal B wired to an “All OK” light.
   • Configure the relay in Momentary mode.

In its resting state (position B, orange LED), the “All OK” light is illuminated. When the momentary switch is activated, it briefly switches the relay to position A, sounding the siren. Once the momentary pulse ends, the relay returns to position B, and the “All OK” light comes back on.

Solid Switch
The solid switch on the GX IO-Extender 150 is designed to electronically switch the positive side of a DC circuit, with no mechanical contacts.

• Bat+ → Connect to the positive terminal of your battery or DC power supply.
• Load → Connect to the positive side of your device or load.
• Bat- → Connect to the negative terminal of your battery or DC power supply.
• The negative side of your load connects directly to Bat- (or a shared ground).
• Configure the relay in Toggle mode.

This setup allows the solid-state relay to switch your load on and off by making or breaking the positive side of the circuit electronically.
If the solid switch is configured as momentary, it will only switch the load on for as long as the control signal remains active.

Software
Node-RED is a low-code programming environment for event-driven applications (https://nodered.org). See the installation manual for more information on the Node-RED and GX device combination: https://www.victronenergy.com/live/venus-os:large.

The following 4 steps are needed to get Node-RED up and running on your system:

1. Set the firmware image type to Large and update the firmware
2. Once rebooted in the large image, enable Node-RED
3. Open the Node-RED dashboard via either VRM under the Venus OS Large menu option or locally via https://venus.local:1881/
4. Pull in the Switch and Switch control node and control the GX IO-Extender 150. These nodes are part of the node-red-contrib-victron package that comes pre-installed with the Venus OS Large image.

Simple digital input control
First, the digital input must be configured to a type using the Settings > Integrations > Digital IO on the GX device, then select a digital input from the GX IO-Extender 150 and set a type.

Supported input types are:

• Pulse meter N/A
• Door alarm Open/Closed
• Bilge pump On/Off
• Bilge alarm Ok/Alarm
• Burglar alarm Ok/Alarm
• Smoke alarm Ok/Alarm
• Fire alarm Ok/Alarm
• CO2 alarm Ok/Alarm
• Generator Running/Stopped
• Touch input control

Once an input type has been selected, a Digital input node can be used to read the status of that input for further use in the flow.

Aumentare PWM

La parte superiore di questo flusso serve per accendere o spegnere la porta PWM utilizzando il parametro di stato PWM. Una volta accesa, la porta utilizzerà il valore PWM impostato tramite il parametro di attenuazione PWM. Il nodo di input legge il valore corrente della porta PWM e lo memorizza nel contesto globale Node-RED.
Il nodo di iniezione inietta un timestamp ogni secondo, che viene sostituito dal valore PWM corrente della porta, aumentato di 25. Se il valore è superiore a 100, torna a 0.

Tieni presente che potrebbe essere necessario modificare lo Switch e la porta PWM utilizzati nel nodo funzione per renderlo funzionale.
