Intrinsically safe signal conversion in a variety of Ex-zone applications – ACT20X combines universal input and output loop supply
Compliance with safety requirements and precision are basic prerequisites for industrial plants with EX areas. Basic security functions, such as switching on and off of aggregates, monitoring of actuators or temperature and pressure control require the support of an intrinsically safe and high-precision signal converter.
With our ACT20X we offer a universal device for the reliable isolation and conversion of intrinsically safe signals. Thanks to its integrated output current loop, the module does not require any additional external power supply and can also be easily used in remote control boxes. Integrated in a housing which is only 12.5 mm in width, the intrinsically safe signal converter takes up little space on the mounting rail.
The latest addition to our ACT20X series is characterised by high accuracy and compliance with all safety requirements for use in Ex-zones 0, 1 and 2.
- Independent of external power supply
Thanks to the output current loop, the intrinsically safe signal converter requires no external power supply as the DCS system supplies the device.
- Protection and robustness
The new ACT20X features high 2-way isolation and 2.5 kV isolation voltage. The intuitive connection system with release levers also simplifies maintenance and detaching of cables.
- Universal application
The comprehensive input has intrinsically safe RTD thermocouple sensors, resistance, potentiometer and DC signals (mA, V), so that information is transmitted quickly and reliably to the control.
- Safe in Ex zones
Comprehensive approvals allow worldwide use in Ex zones 0, 1 and 2.
- ACT20X – intrinsically safe signal converters for Ex zones
Signal converters of the ACT20X product family are specifically designed for hazardous and non-hazardous applications. They process signals from Ex zones 0, 1 and 2 for the control and meet the strict standards of the process industry. Using FDT/DTM software, you can configure the ACT20X modules for different applications. International approvals such as IECEx, ATEX, FM and UL allow them to be used all over the world.
