Terminal wiring diagram
HJ5207 (32 PNP/NPN inputs)
Terminal wiring method
Connect to power supply/RS485-1/2/cascade expansion
The first RS485 port: A1, B1 and GN1 (RS485 digital ground).
The first RS485 port: A2, B2 and GN2 (RS485 digital ground).
Cascade expansion module interface: LRX, LTX.
Digital input wiring method
CM1, DI/0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7 are grouped into a group, CM2, DI/1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7 are grouped into a group, the common terminal CMx (x value 1, 2, 3, 4) is connected to 0V or 24V. If the common terminal is connected to 0V, the output type of the input DI point connection is PNP mode. If the common terminal is connected to +24V, the output type of the input DI point connection is NPN mode.
