Product Description:

The EL1008 digital input terminal is produced by Beckhoff and belongs to the EL EtherCAT Terminals series. It functions as an eight-channel input slice that converts field-level switch states into EtherCAT process data, streamlining signal collection in industrial automation cells. When it is installed beside other bus couplers on a DIN rail, the module expands a node’s input capacity without requiring extra wiring or a separate external power supply for the terminal electronics.

This terminal uses a control supply of 24 V DC, so sensors tied to the module share a common low-voltage source typically present in machine cabinets. It provides 8 discrete input channels that are mapped into the controller’s process image, permitting bit-level diagnostics and rapid program access. Each channel uses a 3 ms input filter that screens out contact bounce while still capturing fast machine events. The integrated power contacts can carry up to 10 A, allowing downstream terminals to receive current without separate feeds. Signal levels conform to EN 61131-2 Type 1/3, which keeps the inputs compatible with most industrial sensors and provides clear switching thresholds for logic HIGH and LOW.

The housing measures 12 × 100 × 68 mm and is molded from polycarbonate, so multiple units line up tightly while remaining electrically insulated. An IP20 protection rating applies, indicating finger-safe openings suited for enclosed panels rather than exposed field locations. Wiring is completed through a 1-wire technique that places each input and its reference on a single plug-in terminal, reducing connector count. The body snaps onto a 35 mm DIN Rail, and its variable installation position allows horizontal or vertical orientation inside the cabinet. No rotary switches are required for address setting because EtherCAT automatically assigns positions during startup. Its slim shape helps keep terminal rows compact where panel space is limited.
