Internal Product Review

The Beckhoff EPP1321-0060 is a compact EtherCAT P box module well suited for decentralized machine I/O architecture. M8 4-pin EtherCAT input and P-coded M8 4-pin EtherCAT P output support clean, efficient field connectivity. A 500 V isolation rating and 24 VDC nominal supply make the module an excellent choice for stable industrial networks.

Product Description:

The EPP1321-0060 is an EtherCAT P box module produced by Beckhoff within the EPP EtherCAT P Box Modules series. Designed for distributed machine segments, this I/O station combines supply lines with high-speed EtherCAT communication so sensors and actuators can be linked over a single hybrid cable. The module sits directly in the field and forwards both power and data, enabling up to ten additional slaves through its cascaded ports to simplify wiring in conveyors, packaging machines, and assembly cells. Its compact enclosure allows mounting on tooling plates or inside cable trays where cabinet space is not available.

The module measures 30 mm wide, 86 mm high, and 22 mm deep, so it fits beside standard sensor blocks on a DIN rail bracket. The polyamide enclosure is sealed to IP67 and carries two M8 sockets. The left socket accepts the incoming EtherCAT P signal, while the right socket routes it onward. The hybrid bus operates from a nominal logic and sensor supply of 24 V DC. Internal electronics draw 100 mA, leaving the power pins available to source up to 3 A for connected field loads. Separate IP and IS current paths prevent disturbances in the data line when inductive loads switch.

For longer networks, the module can pass a cumulative UP current of 4 A to downstream boxes. Its galvanic isolation withstands up to 500 V between the field supply and control circuitry. An allowable EtherCAT P cable length of 70 m between active nodes permits connections across large machines without intermediate repeater stations. The body is molded from PA6, which provides resistance to oils and coolants commonly encountered on factory floors. Clearly coded P-type M8 outputs help prevent incorrect connections when several field modules are installed in the same area. The sealed housing also protects internal connections from dust and temporary exposure to water during normal machine operation.
