Signal Conditioning

IS Signal Isolators | Solenoid Drivers | Temperature Transducer | Universal Signal Converter
Current Supply Isolator | Current Output Isolator

Hazardous area signal conditioners maintain a barrier between Ex and Safe zones whilst allowing digital or analogue signals to pass through unimpeded. Weidmuller’s ACT20X series contains both signal isolators and solenoid/alarm drivers, allowing for bidirectional communication of digital and analogue signals between zones.

The ACT20X series is IECEx certified and all models can be configured via FDT/DTM software. This allows for fast implementation of complex setups as well as simple ongoing maintenance. High density applications are now possible with dual channel isolators available in a 22.5mm wide housing. All devices also include an alarm function which in the case of cable or sensor failure alerts the control system.

Models are available to suit HART, DC, RTD, thermocouple, simple switching and NAMUR input signals, and analogue or digital output signals.
