Product Description:
Beckhoff manufactures the EPP1008-0022 for its EPP EtherCAT P Box Modules series. The unit is a decentralized digital input module that couples 24 V sensors to an EtherCAT P trunk while daisy-chaining both power and communication through the same hybrid cable, without requiring separate power conductors for the box. In automated assemblies, packaging lines, or material-handling stations, the device captures on/off states close to the field element and forwards them to the controller, thereby shortening signal runs, limiting cabinet terminations, and simplifying machine layouts that demand modular I/O nodes near moving machine sections.
The EPP1008-0022 provides 8 input channels, each scanned by a 3.0 ms input filter to suppress mechanical bounce and short electrical transients before values enter the process image. A rated supply of 24 VDC powers the module and the connected sensors through its EtherCAT P feed. Wiring is handled with a screw-type M12 connection that secures conductors against vibration. Status LEDs are mounted next to each port, and these LEDs show channel state and diagnostic information without external tools. Inside the EtherCAT frame, process data occupy four bytes so that X01 through X08 map directly to controller variables, allowing deterministic updates without additional protocol overhead.
The network architecture is supported by 1 input + 1 downstream EtherCAT P ports, enabling a simple line topology without extra junctions in distributed I/O layouts. All signal paths are electrically isolated from the internal logic to help prevent ground loops when sensors share different reference potentials. Field devices connect through an 8 x M12 socket signal interface, and each socket follows the standardized pin arrangement 1:+24 V U, 2:n.c., 3:GND, 4:Input, 5:n.c. so premolded cables can be used without rewiring.
