Introduction
The Z-D-IN module acquires 5 single-ended digital signals, then converts them
to a digital format (IN 1-5 state).
The supported communication protocol is Modbus RTU.
The following counters are available:
4 counters at 16 bit
1 counter at 16/32 bit (configurable).
Features
- Acquisition of digital signals from sensor: Reed, NPN, PNP, Proximity, contact, etc…
- Counters are saved to a non volatile memory (NVM)
- Input signals can be filtered
- Pulse counters for digital signals, with max frequency equal to: 100 Hz for 16bit-registers (the signal is acquired from IN1-4); 10kHz for 32bit-register IN5
- Node address and baud-rate configurable from Dip-Switches
- RS485 serial communication with MODBUS-RTU protocol.

USER MANUAL – Z-D-IN
POWER SUPPLY
Supply voltage| 10 – 40 Vdc or 19 – 28 Vac ( 50Hz – 60Hz)
Power consumption| Min: 0.5W; Max: 2.5W
The power supply transformer necessary to supply the module must comply with
EN60742 (Isolated transformers and safety transformers requirements).
To protect the power supply, is recommended to install a fuse.
Input connections
Power on the module with < 40 Vdc or < 28 Vac voltage supply.
These upper limits must not be exceeded to avoid serious damage to the module.
Dip-switches table
Power off the module before configuring it by Dip-Switches to avoid serious damage due to electrostatic discharges.
In the following tables: box without circle means Dip-Switch=0 (OFF state); box with circle means Dip-Switch=1 (ON state).

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
