4.6 Digital Input·Output Circuit
The digital signals consist a shielded circuit by Photo Coupler as like Fig 4-5.
The Input signal consists the common input signal DIN_COM and 24 DIN signals and
flow the proper current by both ends 12V/24V.
The output signal DOUTx is connected the Cathod signal of Photocoupler TR and
common signal DOUT_COM is connected the Emitter. 12V/24V input voltage controls the
current to less than 20mA.
