ER8309-1022 | Multi-functional I/O box

The ER8309-1022 EtherCAT Box has various digital and analog 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 ER8309-1022 offers a compact solution for the most diverse units that can be controlled over EtherCAT.

The EtherCAT Box modules with zinc die-cast housing are ready for use in harsh industrial and process environments. With the fully sealed design and metal surfaces the ER series is ideal for applications requiring enhanced load capacity and protection against weld spatter, for example.
