ER2318-000x | 4 x digital input + 4 x digital output 24 V DC, Imax = 0.5 A, 10 µs

The ER2318 EtherCAT Box combines four digital inputs and four digital outputs in one device. The outputs handle load currents of up to 0.5 A, are short-circuit-proof and protected against inverse polarity. The state of each signal is indicated by means of light emitting diodes. The signals are connected optionally via screw type M8 connectors (ER2318-0001) or connector M12 screw type (ER2318-0002).

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.
