 Connect PNP (SOURCE) type load to R2-ECx004 input 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 input point (X15). The structure is the same for the other
15 input points (X01 - X14). The rated voltage is 24 V
DC
for the input port and module power
port. Do not use a power supply exceeding 28.8 V
DC
or an AC power supply to avoid damaging
the module circuit.

WAR NING
Follow these instructions for power supply and wiring to prevent any danger.
 Use two independent 24 V
DC
power supplies for the module and the common input /
output points to ensure proper operation.

Use 26 - 18 AWG wires for wiring.
