ER2028-1032 | 8-channel digital output 24 V DC, IMAX = 2.8 A (∑ 16 A)

The ER2028-1032 EtherCAT Box with digital outputs connects the binary control signals from the controller on to the actuators at the process level. The eight outputs handle load currents of up to 2.8 A each, although the total current is limited to 16 A.

The signal state is indicated by means of light emitting diodes. The signals are connected via M12 screw type connectors. All outputs are short-circuit-proof and protected against inverse connection.

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.
