418 MHz Receiver and 900 MHz Receiver with Analog Output Modules Termination
Termination Notes for 418 MHz and 900 MHz Systems:
1. The wireless receiver and Analog Output Modules are interconnected and require module power along the “Power Bus”
terminals. The bus can be powered from either the receiver end on the left or the last output module on the right side. Be sure
you have enough DC current or AC VA for all the devices on the bus.
2. The Current Output Module (BA/COM) signal is LOOP POWERED and must be externally powered with 9 to 36 VDC
separate from the Power Bus. The Loop Power must be connected to the Current Output Module before it can be trained.
3. Be sure to follow the polarity (+ or –) symbols listed on each receiver and the output modules to maintain communication and
Power Bus integrity.
