Process Signal to Bi-Polar Current Converter

These converters are designed to provide a bi-polar current output from  standard process control inputs. 

They have a standard and high speed output reponses, up to 1 kHz.

Current outputs available are up to ±100 mA.

Voltage compliance (maximum) is ±12 V.

We have a range of auxiliary supplies available wide range mains, 230 or 115 VAC and several DC ranges.

Customized input and output requirements can usually be met on request.

Galvanic isolation between input and output.

An analogue filter with adjustable time constant between 0 and 20 seconds is also provided for the filtering of noisy signals.

Applications:

DC servomotor drive.
Hydraulic valve control.
Test systems.
Electrochemical testing.
