Unitronics IO-RO16, IO-RO16-L User Manual
IO-RO16, IO-RO16-L I/O Expansion Modules 16 Relay Outputs
The IO-RO16 and IO-RO16-L are I/O
expansion modules that can be used in
conjunction with specific Unitronics OPLC
controllers.
The modules are identical except for their
power supply specifications: IO-RO16 runs
at 24 VDC; IO-RO16-L at 12 VDC.
Each module offers 16 relay outputs.
The interface between a module and the
OPLC is provided by an adapter.
These modules may either be snapmounted on a DIN rail, or screw-mounted
onto a mounting plate.
