EP8309-1022 | Multi-functional I/O box

The EtherCAT Box has various inputs and outputs: eight digital inputs/outputs, two digital tacho inputs, two analog inputs, one analog output and a 1.2 A PWMi 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 PWMi 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 the most diverse units that can be controlled over EtherCAT.
