When it comes to recording analogue measured values, compliance with safety regulations and maximum precision are basic prerequisites for industrial plants. Basic security functions, such as switching units on and off, monitoring actuators or controlling temperature and pressure, require the support of high-precision signal converters.
With our ACT20X and ACT20P products, we are providing you with universal devices that will reliably isolate and convert signals from intrinsically safe or safe zones. Thanks to the integrated output current loop, the modules do not require any additional external power supply and can also be easily used in remote control boxes. Integrated in an enclosure that measures a mere 12.5 mm wide, the signal converters take up very little space on the DIN rail.
The latest addition to our ACT20X series is characterised by high precision and compliance with all the safety requirements for use in Ex zones 0, 1 and 2. Also, the ACT20P ITX+ offers extended input properties, such as measurement of +/-300 V AC/DC voltages and currents of up to+/-5 A DC. It even features a digital output for indicating limit values.
The great advantage of a signal converter in applications involving direct, on-site recording of measured values from temperature and pressure sensors is that it can be used independently of the power supply
Predestined for field use
The combination of all-purpose input and output loop supply makes the ACT20X a unique product solution for the process industry and plant manufacture. But the advantages of this solution really do come into their own especially when the device is used e.g. in remote cabinets in the mining industry – both above and below ground – or in overburden materials handling.
Numerous alarm functions
To name but a few examples, the alarm functions include the window alarm, alarm delay, wire-break recognition and hysteresis, so the solutions offer the very best conditions for any and all process requirements.
The intuitive connection system with release levers simplifies maintenance and detaching of lines.
Safe in Ex zones
Comprehensive approvals allow for use around the globe in Ex zones 0, 1 and 2.
The extensive input features RTD thermal sensors, resistance signals, potentiometer signals and DC signals (mA, V), so the widest range of input signals can be connected to standard I/O sub-assemblies.
Your signal in safe hands
Whether they’re deployed in the process industry, machine construction or energy technology, analogue signal converters from Weidmüller’s ACT20 series convert and protect your analogue signals in a wide variety of applications. Using FDT/ DTM software, you can configure a multitude of ACT20 models for diverse requirements. International approvals such as IECEx, ATEX and UL allow them to be used around the globe.
