1. 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).
1.1. 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.

Filter
Configurable between: 1[ms] and 250[ms]
Sensor=closed
The sensor is detected «closed» if: acquired signal voltage >12 Vdc
and acquired signal current > 3 mA
Sensor=open
The sensor is detected «open» if: acquired signal voltage <10 Vdc
and acquired signal current < 2 mA
CONNECTIONS
RS485 interface
IDC10 connector for DIN 46277 rail (back-side panel)
1500 Vac ISOLATIONS
Between: power supply, ModBUS RS485, digital inputs

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.

3. 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.

4. 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).

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
For more info refers to:
http://www.modbus.org/specs.php
5.1. Abbreviation used
In the following table this abbreviations are used:
“MS” = Most significant
“LS” = Less significant
“MSB” = Most significant Bit
“LSB” = Less significant Bit
“MSW” = Most significant Word (16 bits)
“LSW” = Less significant Word (16 bits)
“R” = Read only register
“RW” = Read and write register
“Unsigned 16 bits” = Unsigned 16 bits register
“Signed 16 bits” = 16 bits register with sign
“Float 32 bits” = Floating point single precision 32 bits (IEEE 754) register
“0x” = Hexadecimal Value (example 0x1234 = 4660 decimal)
“0b” = Binary Value (example 0b1110 = 14 decimal)
Default communication parameters are 38400 baud, 8bit , parity None, 1 stop bit.
