8DI/4RO Digital Input and Output Module

ADM-4184

Product introduction

ADM-4184 is a 8 Channel digital input and 4 Channel (normally open) relay output

module, which is used in industrial field signal acquisition, monitoring and control.

Support 8 channel isolation digital input and 4 channel A-Type relay output. RS-485

communication interface, support the MODBUS RTU protocol. It is can connect

configuration software, PLC, DCS, industrial control touch screen.

LED directive definition

1. POWER: power status indication, "bright" power supply is normal

2. COMM: RS-485 communication indication, "flash" is sending and receiving data

3. DI0~DI7: digital input indication, "bright" digital input is 1

4. RO0~RO3: relay output indication, "bright" relay RO and COM closure


Using the default communication parameters

When you forget module communication (ID, baud rate, parity bit), the INIT and

VS- pins are short circuited, module electrifying, The communication parameters of the

module are (9600, N, 8, 1), ID is 1.

INIT and VS- pin is disconnected, module using parameters set by the user, default

settings for the module (9600, N, 8, 1), ID is 1.
