Introduction
The EP8309-1022 has various inputs and outputs: eight digital inputs/outputs, two digital tacho inputs, two analog inputs, one analog output and one current-controlled 1.2 A PWM output.
The current signals have 12-bit resolution. The tacho outputs supply a speed-dependent velocity or frequency value via digital 24 V sensors. Proportional valves, for example, can be actuated directly using the PWM output, while intelligent valves are switched by the analog output.
With its combination of inputs and outputs, the EP8309-1022 offers a compact solution for a wide variety of aggregates that are to be controlled via EtherCAT.
