Weidmuller ACT20M 6 mm temperature isolation and conversion module

Weidmuller has expanded its ACT20M 6 mm temperature isolation and conversion module range. The six new models are available as thermocouple or RTD stand-alone units as well as combined RTD and thermocouple models. Users can also choose between isolated and non-isolated models.

All the temperature models are available as output loop-powered or 24 VDC powered units. They also feature a DIP switch selection for zero, the full-scale range setting and output selection.

The RTD and thermocouple devices are said to be very reliable and offer a high accuracy reading to within 0.1% of measuring range. Depending on the unit, the measuring range is from -200 to +1370°C.

The operating temperature range is -25 to +70°C to ensure the units meet demanding applications. The output voltage is selectable from 0-5, 1-5, 0-10 and 1-10 V and the current can be adjusted between 0-20 or 4-20 mA. The output response times are set at 30 ms intervals.

For maximum convenience, the models measure only 6 mm in width, and are quite small and compact. They are suitable for use in industrial, automation and mining applications.

They also provide 2.5 kV as well as three-way isolation (between input/output/power supply). 24 VDC can be supplied via a DIN rail bus that eliminates individual wiring and minimises installation time.
