Product Description:

The EP6224-0002 is a decentralized digital input module from Beckhoff that belongs to the EP Digital Input Modules series. It mounts directly on machinery and links field sensors to the higher-level controller over an industrial network. By converting discrete signals into process data, the unit streamlines wiring in conveyor lines, packaging equipment, and other distributed I/O arrangements that rely on real-time updates.

The module operates from a nominal supply of 24 V DC and communicates through the EtherCAT protocol, so cyclic input data are transferred with microsecond accuracy. Fieldbus connections use two 4-pin M8 sockets, and these shielded, A-coded connectors also carry auxiliary power. Each of the four channels draws only 3 mA and is routed through a 10 µs filter that suppresses contact bounce before the controller sees a state change. The inputs follow IEC 61131-2 Type 3 characteristics and accept signals over machine cabling up to 30 m in length. A five-pin, A-coded M12 socket is reserved for sensor supply and fits standard industrial cordsets. Channel status is indicated by integrated yellow LEDs so input states can be checked without opening the cabinet.

An additional internal hub exposes IO-Link functionality in parallel with the discrete channels. Four Class A master ports comply with the IO-Link V1.1 standard; each port can source up to 1.4 A/Port on the L+ line while the C/Q pin supports a device draw of 200 mA. Point-to-point IO-Link drops are permitted over unshielded cables up to 20 m, and the logical connection count is fixed at 4 ports, which matches the number of digital inputs for symmetrical installation planning. Class A pin assignment keeps the auxiliary supply separate from signal conductors, reducing crosstalk when sensors operate in mixed switching and serial-data modes.
