Signal Conditioning

Our range of signal conditioning includes 4-20mA loop powered isolators, signal isolators and signal converters. All of our isolated signal converters are DIN rail mounted and are typically amongst the most competitive, compact and innovative on the market.

Signal converters are available for 4-20mA, voltage, RTD and thermocouple inputs as well as more specialised applications such as ac volts and current, mV and even thermocouple isolators with a mV output !

Typical outputs include 4-20mA, 0-10V, 1-5V, other outputs such as mV are also possible.

If you don't see what you need here please contact us as we may be able to either design what you need or adapt an existing design for your application

For more information please view our Signal Conditioning technical note.
