R223C16 12V 16 Channel RS232 Relay Module
RC232 16 channel relay development board to easily control the relay via RS232 Supply voltage is taken through the terminal on the PCB. Each relay can operate with 250V AC/10A or 30V DC 10A.
Usage Areas
Remote control, remote measurement system
Wireless meter
Smart Home, Home Automation
Access control
ID system
Data collection
IT home appliance
Baby monitoring system
LED Motorized PLC
PC Remote Control
Relay Output:
NC: The normally closed end shorts to COM before the relay activates and cut off after activation.
COM: Common terminal.
NO: Normally open end, relay is closed before activation and then short circuits COM .
