8 channel A type NC relay 8DO output Module RS485 MODBUS RTU SD01

8 channel A type NC relay 8DO output Module RS485 MODBUS RTU SD01

Description:
Modulenya is a 8 channel relay switch output module, which is used in the signal
control of industrial device. Support 8 channel A type normal open relay output, the
relay capacity is 3A @250VAC/30VDC. RS-485 communication interface, support the
MODBUS RTU protocol, can connect configuration software, PLC, DCS industrial control
touch screen.

LED indicator definition
1. POWER: power status indication, “bright” power supply is normal
2. COMM: RS-485 communication indication, that “flash” is sending and receiving data
3. RO0~RO7: relay action indication, “bright” relay is closed
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.
