For maximum safety in industrial applications.
Isolating amplifiers and measuring transducers are important components in modern industry. They play a decisive role in safe signal transmission and conversion, particularly due to their ability to provide galvanic isolation and EMC filtering. These measures protect systems from voltage peaks and at the same time ensure reliable signal quality.
With a wide range of input signals, functions (i.e. temperature measuring) and signal outputs, such as 4–20 mA active/passive or 0–10 V, our measuring transducers offer maximum flexibility and can be easily integrated into existing systems.
Whether in the process industry, water and wastewater treatment, building infrastructure, power distribution and generation, mechanical engineering, shipbuilding or modern data centres – our solutions make the difference.
With international certifications and application-specific approvals, Weidmüller isolating amplifiers and measuring transducers guarantee reliability in any ambitious industrial environment – worldwide.

Weidmüller ACT20M and ACT20P series isolating amplifiers and measuring transducers guarantee precise signal conversion and galvanic isolation – essential for reliable process control. They impress with their high flexibility and simple configuration, so that they can be perfectly customised to your specific requirements.
With a width of just 6 mm for the ACT20M series and 12.5 mm for the ACT20P series, they offer a space-saving solution in the control cabinet. The ACT20D process value displays can be installed on switchboards, closed control cabinets and decentrally in the field.
The ACT20X isolating amplifier from Weidmüller has been specially developed for potentially explosive zones and fulfils the highest safety standards in Ex zones 0, 1 and 2 thanks to ATEX and IECEx certifications. With SIL approval in accordance with IEC 61508, this series guarantees maximum safety for critical applications.
The ACT20C measuring transducers offer real-time remote monitoring and diagnostics via Ethernet, enabling seamless integration into industrial networks. The smart calibration function improves maintenance and increases measurement accuracy.
6 mm 's slim PICOPAK series offers reliable signal isolation and conversion while saving valuable space in the control cabinet.
The compact components guarantee precise, interference-free signal transmission, which is crucial for automation processes in the automation and process industry.
The particularly compact design in terminal block format with PUSH IN connection allows integration even under difficult installation conditions – especially in space-optimised systems.
The ACT20C products precisely monitors single-cells and stack voltages in hydrogen stacks and battery storage systems up to 1500 VDC.
The PICOPAK isolating amplifiers and measuring transducers reliably transmit signals and convert measured values in the automation and process industry.
The frequency measuring transducer ACT20M converts pulses or frequencies in industrial control systems into an equivalent current signal. For example, it records and monitors the speeds of motors and machines.
In many industrial plants, process values such as pressure or temperature must be reliably displayed and monitored. ACT20D process value displays visualise important process values on site and can be used flexibly. The proven ACT20 series is complemented by ACT20D process value displays.
