AHT Series
SKU: AHM Series

View our informative technical factsheet for our AHM Transmitters and Trip Transmitters.

The input(s), contacts, supply and earth are fully isolated.

Whether the function is RTD single, RTD differential, Voltage, Current, Slidewire, Frequency, Strain Gauge etc take a look below.

Another standard feature is that the optical drive is up to 20mA into a 20V loop (current) and up to 10V at up to 20mA loading (voltage).

If you are looking for a specific model, take a look at our Datasheet Centre.
