Wiring Diagram

Hardware connection of IO expansion module

LTX/LRX are respectively connected to the LTX/LRX terminals of HJ52XX series devices

PNP output wiring method

M1, DQ0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 24V are a group, the common terminal M1 is connected to 0V, and the 24V power terminal is connected to +24V of the power supply.

Digital input wiring mode

CM1, DI/0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7 are divided into one group, CM2, DI/1.0, 1.1, 1.2, 1.3, 1.4, 1.5,
1.6 and 1.7 are divided into a group, the common terminal CMx (x value is 1, 2, 3, 4) is connected to 0V or 24V, if the common terminal is connected to 0V, the output type connected to the input DI point is PNP mode, if the common terminal is connected to + 24V, the output type connected to the input DI point is NPN mode.

The following figure shows how to connect the PNP output type:

The figure below is how to connect the NPN output type
