trodeks offers a general-purpose signalconditioning product designed to augment the capabilities of any Programmable Logic Controller (PLC). These signal conditioners allow normally incompatible signalsand loads (AC inputs, AC outputs, etc.) toeasily interface with any PLC.Three categories of these products areavailable — those which convert AC inputs to DC outputs and DC inputs to AC outputs, those which drive specialized digitaloutput loads, and those which allow analogsignals 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 VacAC inputs to 24 Vdc (8 points).

Three signal conditioning devices allowthe standard 24 Vdc, 0.5 A outputs of a PLC to drive specialized loads. The solid-state HE-XDQA allows a 120/250 Vacload to be driven at up to 2 A (four points).The solid state HE-XDQD will drive a24 Vac/24 Vdc load at up to 3 A (four points).The HE-XDQR provides relay outputs that can drive up toa 10A load, supporting voltages of120/250 Vac and 24/30 Vdc (four points).

Two signal conditioning devices providea PLC with additional analogoutputs, by converting 24 Vdc PWM outputsalready present on the controllers. TheHE-XPC converts 24 Vdc PWM outputs to4 to 20 mA (2 channels), while the HE-XPVconverts 24 Vdc PWM outputs to 0 to 10V(two channels).
