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

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.
