1. Introduction
The Z-10-D-IN module acquires 10 single-ended digital signals and converts them to a digital format (IN 1-10 state). The supported communication protocol is Modbus RTU.
The following counters are available:
- 8 counters at 16 bits
- 2 counters at 32 bits
1.1. & 2. Features
Key features of the Z-10-D-IN module include:
- Acquisition of digital signals from various sensors: Reed, NPN, PNP, Proximity, contact, etc.
- Counters saved to non-volatile memory (NVM).
- Input signals IN1-IN8 can be filtered.
- Pulse counters for digital signals with maximum frequencies: 100 Hz for 16-bit registers (acquired from IN1-8); 10 kHz for 32-bit registers (acquired from IN9-IN10).
- Advanced pulse management for digital signals IN9-IN10.
- Up to 10 sensors powered by internal supply voltage (Vaux = 16V).
- Node address and baud-rate configurable via Dip-Switches.
- RS485 serial communication with MODBUS-RTU protocol, supporting up to 32 nodes.
Input Specifications
| Parameter | Details |
|---|---|
| Number of Inputs | 10 |
| Input filter cut-off frequency | 100Hz (for IN1-8); 10kHz (for IN9-10) |
| Filter configurable | Between: 1[ms] and 254[ms] |
| Protection | Provides inputs and power supply (Vaux) protection against overvoltage surge transients via TVS (600W/ms). Max current supplied from Vaux is 100mA (limited by internal series PTC). |
| Pulse min duration (ton) | 4ms (for IN1-IN8); 50µs (for IN9-IN10) |
| Sensor=closed condition | Detected if: acquired signal voltage >12 Vdc and acquired signal current > 3 mA |
| Sensor=open condition | Detected if: acquired signal voltage <10 Vdc and acquired signal current < 2 mA |
3. Input Connections
Power the module with a supply voltage less than 40 Vdc or 28 Vac. These upper limits must not be exceeded to avoid serious damage to the module.
Internal supply Vaux: The screw terminal 12 (Vaux) supplies 16 V with reference to screw terminal 1 (GND).
Measure error for frequency: 2% of fmax (for IN1-IN8: ±2Hz; for IN9-IN10: ±200Hz).
Measure error for period, ton, toff: 1ms.
Diagram Description: Schematic diagram illustrating the input connections for two Z-10-D-IN modules. Each module shows Vaux (16 Vdc supplied from module) connected to terminal 12, and GND to terminal 1. Input signals IN1 through IN10 are shown with associated switches (S1-S10).
Connections:
- RS485 interface: IDC10 connector for DIN 46277 rail (back-side panel).
- 1500 Vac ISOLATIONS: Between power supply, ModBUS RS485, and digital inputs.
Power Supply
| Parameter | Details |
|---|---|
| Supply voltage | 10 – 40 Vdc or 19 – 28 Vac (50Hz - 60Hz) |
| Power consumption | Min: 0.5W; Max: 2.5W |
The power supply transformer must comply with EN60742 (Isolated transformers and safety transformers requirements). It is recommended to install a fuse to protect the power supply.

5. Modbus RTU Protocol
All registers are "Holding register" (Read Modbus function 3) with the convention that the first register is the 40001 address.
The following Modbus functions are supported:
- Read Modbus Register (function 3)
- Write Single Modbus Register (function 6)
- Write Multiple Modbus Registers (function 16)
All values in 32bits are stored into 2 consecutive registers.
