Input circuit
When an input terminal and a COM terminal are connected with no-voltage contact or NPN
open collector transistor, the input turns on. Two or more input COM terminals are con-
nected inside the PLC.
•
Operation indication
While input is turned on, the input indicator LED is lit.
•
Circuit insulation
The primary circuit and the secondary circuit of input are insulated by photocouplers, and a
C-R filter is provided in the secondary circuit to prevent malfunction caused by chattering in
input contacts or invasion of noise from input lines.
