WS-RS232IO4 RS232 interface Network 4-Channel Relay Controller

Brief Introduction:

The equipment has four relay output ports and four input ports, compatible with RS232 and RS485 communication mode. The equipment can be used in some control fields, such as lighting, electromechanical, automatic door, etc. It can realize the automatic control of some large currents. The connection is simple and the operation is easy to operate by computer remote control. The equipment is powered by 12V/DC and the output can be controlled by 220V/AC/10A.

Introduction: there have two functions for RESET button:

(1). When relay is closed, press the button 1S to be released and then the relay will be immediately open

(2). In any condition, press the button more than 10S (RX, TX bright on) then release, device will be going back to factory default setting, so the address ID is changed to 1 and communication baud rate is changed to 9600BPS.
