OMEGA offers several general-purpose signal
conditioning products designed to augment
the capabilities of any programmable logic
controller (PLC). These products allow
normally incompatible signals and loads (AC
inputs, AC outputs, etc.) to easily interface
with any PLC.
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
outputs to be generated from digital, PWM
outputs.
One model allows the connection of AC
signals to PLCs having only digital inputs:
the HE-XDIA converts 120/240 Vac inputs to
24 Vdc (8 points).
Three signal conditioning devices allow
the standard 24 Vdc, 0.5 A outputs of the
XL Series OCS 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 mechanical HE-XDQR can drive up to
a 10A load, supporting voltages of
120/250 Vac, and 24/30 Vdc (four points).
Three categories of these
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 (two channels).
