Product Description:
The EPI1008-0001 is a digital input module produced by Beckhoff as part of the EP Digital Input Modules series. It converts on-off states from external sensors into serial data that an IO-Link master can process, simplifying wiring in distributed control architectures. By installing this block close to the process, machine builders shorten sensor cable runs and reduce cabinet space, making the unit suitable for compact machinery and material-handling stations where reliable 24 V signaling is needed for deterministic operation.
In operation, the module exchanges cyclic process data with the controller at a rate of 230.4 kbaud, the highest speed offered on COM 3, so scan times remain short even when all channels toggle quickly. Each input is referenced to a common 24 V DC supply, and the housing provides 8 galvanically isolated channels built to the Type 3 standard. A high signal is guaranteed when the terminal sees at least +11 V, while a low state is accepted up to +5 V, enabling reliable detection despite voltage drops in long sensor cables. The typical current drawn by an energized channel is 3 mA, and an internal filter, factory set to 3 ms, suppresses contact bounce; integrator settings can be widened to 20 ms or combined with a pulse-stretching function that holds short edges for up to 100 ms. The sensor supply line can source 0.5 A to connected devices without overloading the polyfuse protection.
The module also has compact dimensions and a sealed housing for distributed installation near the machine. The profile measures 30 × 126 × 26.5 mm, so multiple units fit side by side on a machine frame without shading airflow. Its enclosure is molded from PA6 (polyamide), delivering impact resistance and sealing for washdown environments. Process data leave the block through a 1 × M12, 5-pin, A-coded connector that carries both IO-Link signaling and auxiliary voltage, and the device follows the V1.1 Class A IO-Link standard for backward compatibility. Sensors attach through eight M8 sockets, and firmware options permit adjustment of the default filter and pulse-extension settings when unusual contact dynamics are expected.
