Arithmetic units & PSU - AHC Series

View our informative technical factsheet for our AHC arithmetic units & PSU's.

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

Whether the function is scale, High or Low select, multiply/divide, sqaure root extractor or liner integrator, 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.
