Input Relay X
PLC input terminals are used to recive the external signal. the input relays are optocoupler to
connect PLC and input terminals
The input relays which are not connected with external devices can be seemed to fast internal
relays
Output Relay Y
PLC output terminals can be used to send signals to external loads. Inside PLC, output relay’s
external output contactors (including relay contactors, transistor’s contactors) connect with
output terminals
The output relays which are not connected with external devices can be seemed to fast
internal relays
