ER2624-0002 | 4-channel relay output 25 V AC/30 V DC

The ER2624 EtherCAT Box has four relays each of which has a single contact. The relay contact is suitable for use at up to 25 V AC or 30 V DC. The EtherCAT Box indicates its signal state by means of light emitting diodes. The ER2624 has potential-free contacts. The power supply is looped through.

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.
