capability,•and•a•low-side•output•with•current•sense.
Note:
•The•CM0504•has•Proportional-Integral-Differential•(PID)•capabilities•that•make•it•possible•to•
control•devices•like•proportional•valves•through•software.•Refer•to•the•appropriate•software•manual,•or•
contact•your•Parker•Vansco•Account•Representative•for•more•details•about•software.•This•section•only•
provides•hardware•connection•information.
