Functioning as a ruggedized distributed I/O solution, the Beckhoff ER2624-0002 industrial Ethernet module coordinates digital signal relaying directly in harsh field environments. Encased in a robust zinc die-cast housing, this IP67-rated EtherCAT Box provides four potential-free relay make contacts (normally open) designed to switch electromechanical loads up to 2 A DC or 0.5 A AC. By implementing direct fieldbus control without an electrical control cabinet, this module shortens cable runs, minimizes signal degradation, and optimizes system layout in decentralised automation topologies.

| EtherCAT Input/Output | 2 x M8 socket, 4-pin, shielded | Tx+, Rx+, Tx-, Rx- (standard EtherCAT transmission lines) |
| Output Channels (1 to 4) | 4 x M12 female, 5-pin, a-coded | Pin 1 & Pin 2: Relay Contact; Pin 5: Functional Earth (FE) |
| Control Voltage Feed | 1 x M8 male, 4-pin | Feed: Us (24 V DC system/sensor power), Up (peripheral/load power) |
| Downstream Power Link | 1 x M8 female, 4-pin | Daisy-chain distribution of Us and Up voltages to next EtherCAT Box |
The ER2624-0002 features a zinc die-cast housing designed to offer superior mechanical resistance and optimal shielding compared to its plastic-clad equivalent, the EP2624-0002. Both models share identical electronic components and pin assignments, allowing direct drop-in replacement within the TwinCAT System Manager software environment without requiring changes to the existing XML device description files.
When switching inductive loads (such as DC contactors, solenoid valves, or brake coils), users must integrate external protective circuits (e.g., recovery diodes for DC loads or RC snubbers for AC loads) directly parallel to the load. Failing to suppress counter-electromotive force (back-EMF) transient spikes will cause contact arcing, drastically reducing the electrical service life of the internal miniature relays below the rated 200,000 cycles.
Ensure that both the Us (system and sensor power) and Up (peripheral voltage) lines are correctly stabilized. Even though the relays are potential-free, the internal logic requires a continuous 120 mA draw from the Us bus. For systems running long daisy-chained power lines, check for voltage drops; any dip below 20.4 V DC (24 V DC -15%) will trigger communication disruptions and cause erratic relay coil actuation.
