Omega offers a general-purpose signal
conditioning product designed to augment
the capabilities of any Programmable Logic Controller (PLC).
These signal conditioners allow normally incompatible signals
and loads (AC inputs, AC outputs, etc.) to
easily interface with any PLC.
Three categories of these products are
available — those which convert AC inputs to DC outputs and DC inputs
to AC outputs, those which drive specialized digital
output loads, and those which allow analog
signals to be generated from digital PWM outputs.
One model allows the connection of AC inputs to
PLCs having only digital inputs: the HE-XDIA converts 120/240 Vac
AC inputs to 24 Vdc (8 points).
Three signal conditioning devices allow
the standard 24 Vdc, 0.5 A outputs of a PLC to drive specialized loads.
The solid-state HE-XDQA allows a 120/250 Vac
load to be driven at up to 2 A (four points).
The solid state HE-XDQD will drive a
24 Vac/24 Vdc load at up to 3 A (four points).
The HE-XDQR provides relay outputs that can drive up to
a 10A load, supporting voltages of
120/250 Vac and 24/30 Vdc (four points).
Two signal conditioning devices provide
a PLC with additional analog
outputs, by converting 24 Vdc PWM outputs
already present on the controllers. The
HE-XPC converts 24 Vdc PWM outputs to
4 to 20 mA (2 channels), while the HE-XPV
converts 24 Vdc PWM outputs to 0 to 10V
