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, can connect configuration software, PLC, DCS industrial control touch screen.
Product specification
Digital input
1. Input channel: 8 Channel dry contact or level signal

LED directive definition
1. POWER: power status indication, "bright" power supply is normal
2. COMM: RS-485 communication indicates that "flash" is sending and receiving data
3. DI0~DI7: digital input indicator, "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 parameters for the module (9600, N, 8, 1), ID is 1.
