Current Measurement and Isolation Without Auxiliary Power Supply

Weidmuller 3/26/2018

Many processes are only possible due to safe conversion and reliable separation of analogue current signals. With impressive performance, our analogue signal converter PicoPak supports the concurrent measurement and galvanic isolation of signals from active field sensors and PLC input cards.

Because of their integrated input and output current loop, the modules do not require any additional auxiliary power supply and can be used easily in remote control boxes. By integrating into a only 6 mm wide housing, the signal converters take up very little space on a DIN rail. Both designs – the proven screw connectors and the convenient PUSH IN connection technology – ensure reliable connections.

Your special advantages

• High flexibility for a variety of applications due to worldwide approvals and an extended temperature range from -40 to +70 °C
• Loop powered to isolate active field sensors without additional auxiliary power supply from active PLC input cards
• Reliable span and zero point calibration via potentiometer
