Product Description:
The EPP2339-0022 is a distributed digital I/O device produced by Beckhoff and included in the EPP EtherCAT P Box Modules series. Designed for cabinet-free installation, the box gathers sensor inputs and switches small loads directly on machines while receiving both data and 24 V power through a single EtherCAT P line. By providing protected sourcing outputs and galvanically isolated inputs, the module simplifies field wiring in industrial automation cells that rely on deterministic networked control.
This module offers 16 digital channels that can be configured individually as inputs or outputs under controller supervision. All logic functions reference the system voltage of 24 VDC supplied on the EtherCAT P backbone, and the box tolerates network segments up to 30 m between modules without repeaters. Communication and power are daisy-chained through 2 × M8, 4-pin, P-coded ports, while field sensors attach on the downstream side via an 8 × M12 socket strip. The enclosure measures 60 × 126 × 26.5 mm, allowing mounting on flat machine surfaces. Signal edges are debounced by an internal 3 ms input filter, and each channel draws only 6 mA when used as an input, keeping the bus supply current at 100 mA.
When configured as outputs, every point can deliver up to 0.5 A per channel from the shared peripheral voltage path, which is regulated at 24 VDC, and the aggregate draw must remain below 3.0 A. Embedded current monitoring limits fault energy, and a detected short is clamped at 1.5 A per channel to protect wiring. The sensor supply provides a separate 0.5 A budget for proximity switches, and the housing is molded from PA6 polyamide to resist oils and shock in typical plant environments. All signaling adheres to the EtherCAT P fieldbus timing, ensuring deterministic update cycles on the machine network.
