XCOM 9 The common voltage of X3/X4/X5/X7/X8
X3、X4、X5、X7、X8: Optically isolated, 5-24VDC, Minimum pulse width = 100μs, Maximum pulse
frequency = 5KHz.
Because the input is an optically isolated circuit, a 5-24V power supply is needed. For example, you can
use the power supply of the PLC when you are using a PLC control system, but if you want to connect a
relay or mechanical switch to the input, you must need a power supply.
XCOM is an electronics term for a single-ended signal connection to a common voltage. If you are using
a sourcing(PNP) input signals, you need to connect XCOM to the ground(power supply -), if you are
using a sinking(NPN) input signals, the XCOM need to connect to the power supply +.
