ModelPD 271 process controllers

ModelPD 271 process controllers are high precision (UP to 0.2%FS,reading) instruments. These controllers feature in low profile,light weight, low energy consumption and flexibility in functionsfor process control. Capable of working with different types oftransducers and transmitters, these controllers are widely used inindustrial process control systems.

ModelPD271 controllers feature dual outputs with front panelconfigurations of dual 4-digits LED displays and four indicators(OUT, AL-1, AL-2 and CAL). They are especially suitable to workwith pressure and temperature transducers and transmitters. Up tothree alarm values can be set: upper limit (main alarm: indicatedby “OUT”), first alarm value (indicated by “AL-1”), and secondalarm value (indicated by “AL-2”).

PD271controllers accept various input signals from mV signal to processvoltage signal (e.g. 0~10Vdc), or current loop (e.g. 4~20mA), bychoosing suitable supplementary output modules. PD-271 can have upto two relay outputs to control external actuator, or have outputof process voltage signals, (e.g. 0~10Vdc), or current loop. RS-485interface for data communication is available as anoption.
