Tips:
1. When receiver connect 100~240VAC power, transmitter don’t need external power supply, transmitter
provide 12VDC power output.
2. The device supports RS485 data transmission.
3. When the load current is within 10A, the overload will automatically fuse the power circuit to realize circuit
break protection.
Adjust Baud Rate Dial Switch as below:
When you use OT-PLC302C-RS4, please follow the below tips as a reference, in order to reduce the fault in the
process of using and the inspection work.
1. Each transmission unit contains one transmitter unit and one receiver unit, when installation, please install receiver
unit at the side of the power supply cabinet, and install transmitter unit at the side of loading equipment.
2. Please make sure power line is disconnected before installation. The metal conductor of the access port should not
be exposed, to avoid short circuit to burn the equipment.
3. Signal transmission cable must be the copper cable. Other material cables will cause the decrease of signal
transmission quality and distance.
4. Long distance cable connection must be formal connection methods, such as welding or using connectors.
