Electrical inputs and outputs
Digital outputs (DO) 8, with changeover contacts, parameters can be freely
assigned, e.g. for measuring range identification; max. load:
24 V AC/DC/1.7 A (total load for all 8 relay outputs in con-
tinuous operation max. 160 W), floating, non-sparking
Digital inputs (DI) 8, designed for 24 V, isolated, freely parameterizable, e.g.
Service interface (front)
