Wiring and Installation

3.2 Output port wiring example

 Connect NPN (SINK) type load to R2-ECx004 output ports

The IO power (IO_24V / IOGND) and module power (24VPWR / PWR_GND) should be two
independent power circuits.
The following figure illustrates a single output point (Y00). The structure is the same for the
other 15 output points (Y01 - Y15). Connect the GND of the output port to IOGND to avoid
output status error. If an inductive load is connected, ensure to connect a flyback diode to both
sides of the inductive load in parallel to protect the output circuit.

Follow these instructions for power supply and wiring to prevent any danger.
 Use two independent 24 V
output points to ensure proper operation.
 Use 26 - 18 AWG wires for wiring.
