degree/Installation
category Polution Degree 2; Installation Category II
Outputs Two analog (0-20 mA or 4-20 mA) outputs. Each analog output can be assigned to
represent a measured parameter such as pH, temperature, flow or calculated
values. Optional module supplies three additional analog outputs (5 total).
