Product Description:

The EP2349-0021 is a compact digital I/O block produced by Beckhoff and assigned to the EP Digital Input Modules series. Designed for field installation outside a control cabinet, the unit collects discrete sensor signals and feeds them directly to an EtherCAT network. By integrating input circuitry and sensor power within a sealed housing, it streamlines wiring on conveyor lines, packaging cells, and other distributed machines.

Each of the 16 input points is sampled individually; a 10 µs hardware filter suppresses contact bounce before data reaches the controller. Communication with the controller is handled through EtherCAT, routed by two shielded M8 sockets that form the module’s bus interface and allow daisy-chain topology. Field devices connect on separate M8 signal ports and are powered from the internal sensor supply, which accepts a 24 V DC load voltage and draws 6 mA per input. The over-molded housing measures 60 × 126 × 26.5 mm, providing a slim profile for mounting on structural aluminum or machine frames. Environmental sealing reaches IP65/IP66/IP67, meaning the electronics remain protected against dust ingress and high-pressure water jets during wash-down procedures.

For installations that span long mechanical runs, the permitted cable distance between sensors and the block is 30 m, while the summed output feeding the downstream devices is limited to 4 A to protect the circuit traces. When actuating valves or logic relays through the pass-through outputs, the module achieves a typical energizing delay of 60 µs and releases in 300 µs, supporting rapid machine cycles without additional drive electronics. The sensor power rail can provide up to 0.5 A on any single connector, and the current per output channel is capped at the same 0.5 A threshold to prevent localized overloads. This operating profile suits decentralized I/O layouts that require fast signal handling and local sensor power along extended machine sections.
