Product Description:

The IP1001-B318-0000 is an industrial I/O device produced by Beckhoff within the IP Compact Box Units series. It functions as a decentralized input module that mounts directly on machinery and relays sensor states to the master controller, allowing control cabinets to remain free of low-level wiring. Built for plant environments where moisture, dust, and mechanical stress are common, the unit ties discrete field signals into the automation network without additional protective enclosures. This layout helps place inputs closer to sensors and shortens field wiring on moving or space-limited equipment.

This module is supplied from a nominal control voltage of 24 VDC; that level powers its electronics as well as the sensor supply rails. Each input draws only 6 mA, letting proximity switches or photo eyes operate without overload. An internal filter of 3.0 ms suppresses contact bounce so controllers receive stable transitions. For cascading nodes, the downstream field line exits through a 4-pin M8 socket, keeping the daisy chain compact. The housing has a protection rating of IP65/IP66/IP67, which blocks dust ingress and resists low-pressure spray or temporary water exposure, making cabinet-free mounting possible even on washdown equipment.

Communication to the higher-level network occurs over PROFIBUS, and the physical bus is routed through an integrated tee connector so trunk and spur segments can be created without extra fittings. The eight input channels each receive up to 0.5 A per channel of sensor power that is sourced through the dedicated power feed port on a 4-pin M8 plug. Internally, the device maps one byte of 8-bit input data into the controller’s process image, so every input updates synchronously on each bus cycle. The unit is not programmable, uses M8 screw-in signal connectors for secure field wiring, and accepts its supply through a separate 4-pin M8 power connector to keep I/O power separate from logic power.
