ELECTRICAL CONNECTIONS

[Warning Symbol] CAUTION: The upper power supply limits must not be exceeded, as this could cause serious damage to the module. Switch the module off before connecting inputs and outputs.

To meet the electromagnetic immunity requirements:

• Use shielded signal cables;
• Connect the shield to a preferential instrumentation earth system;
• Separate shielded cables from other cables used for power installations (transformers, inverters, motors, etc.).

Power Supply Connections

Terminal 20: + / ~

Terminal 21: ~ | -

Terminal 22: +

RS485 SERIAL PORT

Terminal 23: B(-)

Terminal 24: A(+)

Terminal 25: GND

Connection to the RS485 port. Polarity is not standardised; in some devices of other brands it may be inverted.

Digital Inputs (PNP)

Inputs from 1 to 8 (Terminals 10, 11, 12, ...)

Inputs from 9 to 32 (Terminals 40, 41, 42, ...)

For correct instrument operation, power the I/Os via the I/O Ext Supply 1 and 2 terminals (e.g., 17, 18+, 19-) at the same time.

Digital Outputs (PNP)

Outputs from 1 to 8 (Terminals 40, 41, 42, ...)

Outputs from 9 to 32 (Terminals 63, 64+, 65-, ...)

[Warning Symbol] CAUTION: The power supply must be sized according to the expected load at the outputs. Terminals 18-64 and 19-65 can be connected together on the same power supply.

DAISY-CHAIN (R-32DIDO-2 / R-32DIDO-2-P ONLY)

[Warning Symbol] CAUTION: IT IS NOT ALLOWED TO CREATE LOOPS WITH ETHERNET CABLES.

Using the daisy-chain connection it is not necessary to use switches to connect the devices. Diagrams illustrate correct daisy-chain connections without loops.

There must be no loops in the Ethernet cabling, otherwise the communication will not work. The modules and switches must be connected eliminating any loops. Diagrams illustrate incorrect connections with loops.

The LAN fault-bypass function allows you to keep the connection between the two Ethernet ports of the device ON, in the event of a power failure. If a device turns off, the chain is not interrupted and the devices downstream of the switched-off one will still be accessible. This function has a limited duration: the connection remains active for a few days, typically 4. The fault-bypass function requires that the sum of the lengths of the two cables connected to the switched off module is less than 100m.

ETHERNET CONNECTION RULES

For the Ethernet cabling between the devices, the use of the unshielded CAT5 or CAT5e cable is required. CAT6 for industrial environments.

FACTORY IP ADDRESS

The default module IP address is static: 192.168.90.101.

WEB SERVER

To access the maintenance Web Server with the 192.168.90.101 factory IP address:

Default user: admin; Default password: admin. Access via: http://192.168.90.101

[Warning Symbol] CAUTION: DO NOT USE DEVICES WITH THE SAME IP ADDRESS IN THE SAME ETHERNET NETWORK.

DIP - SWITCH SETTINGS

[Warning Symbol] WARNING: The DIP-switch settings are read only at boot time. At each change, perform a restart.

DIP-SWITCH SW1: through DIP-SWITCH-SW1 it is possible to set the IP configuration of the device:

[Warning Symbol] WARNING: DIP-SWITCHES are located on the back of the device. To access the DIP-SWITCH it is necessary to remove the bottom of the instrument.
