N4D3E16_PRO 16CH Bidirectional Digital IO Module – RS485 Modbus RTU Full-Duplex Transparent Transmission DIP Switch Board for PLC Expansion

N4D3E16_PRO is the latest 16-channel bidirectional remote control module launched by eletechsup. It only requires a pair of RS485 buses and a simple setting of DIP switches for remote control, without the need for computer or PLC assistance.




N4D3E16 PRO, upgrade part
1 Use a DIP switch instead of a command to enable transmitting and receiving.
2 Switching quantity bidirectional full-duplex transparent transmission
3 The RS485 interface uses TVS anti-surge protector
4 The microcontroller uses a high-precision low-temperature drift crystal oscillator
5 Using KF128-5.0 terminal block, wiring is easier
6 with RESET factory setting jumper

Description:

1 Working voltage: DC 8-25V (9V 12V 24V)

2 Working current: 7-32MA

3 16CH photoelectrically isolated NPN input ports

4 16CH Darlington transistor outputs (ULN2803 NPN output)

5Command has multiple output modes: six output modes: Open/Close/Toggle (Self-locking)/Latch(Inter-locking)/Momentary (Non-locking) /Delay .

6 The input port can remotely control the output port of another board through the RS485 bus

7 MODBUS command supports 03 06 16 function code.

8 The maximum delay under MODBUS command 1 is 255 seconds.

9 In MODBUS command mode, up to 64 devices can be supported in parallel.

How to enable remote two-way control function:
1 Prepare two N4D3E16_PRO boards.
2 Set the DIP Switch A0-A5 of the two boards to the same value. It is recommended to set it to 1
3 Set the DIP Switch Tx of one of the boards to ON, and set the Rx of the other board to ON.
4 Use the RS485 bus to connect the two boards
5 Power on
