Product Description:
The EL2911 is a safety power switching terminal produced by Beckhoff within the EL EtherCAT Terminals series. Designed for machine-building and process cells, the unit disconnects or energizes 24 V field circuits through an internal relay commanded by a Safety over EtherCAT controller. By integrating with the EtherCAT I/O strand, it allows decentralized shutdown of actuators without requiring additional wiring between the safety controller and each field device.
The terminal feeds ohmic, inductive, or lamp loads. Its output stage can source up to 9 A continuously with a nominal bus supply of 24 V DC, placing electromagnetic coils and resistive heaters within its supported range. Installation is simplified by a 35 mm DIN rail clip that locks the housing onto standard control cabinet rails. Functional safety communication is handled through Safety over EtherCAT, so the switching command and feedback are transmitted with certified CRC monitoring. Inside the module, one galvanically isolated path provides 1 output channel, which simplifies validation of the safe off state for a single actuator. The circuitry also remains stable against the inrush currents generated by tungsten lamps because the output supports this type of load.
The electronics are protected by an IP20 enclosure, so the terminal must be installed inside a control cabinet and protected from dust and dripping water. The device operates at ambient temperatures from 0 °C to +55 °C without derating, supporting use in typical industrial control cabinets. It can be stored at temperatures from -25 °C to +85 °C without loss of performance when subsequently installed. A short-circuit-proof output stage trips internally and automatically recovers after the fault is cleared, preventing field wiring faults from affecting the upstream 24 V supply. This automatic response reduces the risk of sustained current flow through a shorted load while allowing normal switching to resume after the wiring issue has been corrected.
