3.1.2 X5, X6, X7 and X8 Digital Inputs
X5, X6, X7 and X8: optically isolated, single-ended, 5-24VDC, minimum pulse width 50μs, maximum
pulse frequency 10KHz
•
X5 can be used as servo on input or general purpose input.
•
X6 can be used as alarm reset input or general purpose input.
•
X7 can be used as general purpose input.
•
X8 can be used as general purpose input.
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. In the case
of SS series, 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 .

software for X5, X6, X7 and X8 function configuration.
