Unitronics IO-DI8-TO8 Manual

IO-DI8-TO8, IO-DI8-TO8-L
The IO-DI8-TO8 and IO-DI8-TO8-L are I/O
expansion modules that can be used in
conjunction with specific Unitronics OPLC
controllers.
The modules are identical except for their
voltage specifications: IO-DI8-TO8 runs at
24 VDC; IO- DI8-TO8-L at 12 VDC.
Both modules offer 8 digital inputs, type
pnp/npn (source/sink), and 8 pnp (source)
transistor outputs.
The interface between a module and the
OPLC is provided by an adapter.
These modules may either be snap-
mounted on a DIN rail, or screw-mounted
onto a mounting plate.
