1.15 Digital Input I/F Circuit
As shown, the internal circuit of the digital input interface can be
selected by grounding DICOM or connecting 24VDC. If grounded,
the external device to be docked is Sink. If connected to 24VDC,
the external device to be docked is Source. Whether it is a gen-
eral-purpose digital input interface or an origin limit interface,
DICOM is used to select the supported device type, which cannot
be set individually. The device could be a proximity switch or a
photoelectric switch. From the interface circuit, all input points are
optically isolated, which helps to resist noise and provide internal
circuit protection of the controller.
