Product Description:
The IE1011-0000 extension box is manufactured by Beckhoff and belongs to the IE Extension Box Units series. This sealed module functions as a digital input block that captures binary signals from proximity switches, limit sensors, or push buttons and transfers them to the control system. By situating the electronics directly on the machine frame, it reduces cabinet wiring, simplifies fieldbus expansion, and supports adaptable layouts in conveyor lines, packaging stations, and material-handling equipment.
Each channel operates with a nominal supply of 24 VDC, the standard control voltage in most plants, so sensors can be powered directly without level conversion. The input electronics draw only 6 mA per channel, minimizing the load on upstream safety relays. A built-in filter with a response time of 0.2 ms suppresses contact bounce and high-frequency noise, ensuring accurate edge detection. Compliance with EN 61131-2 Type 2 means that the digital inputs meet the applicable requirements for this input category. The module offers 8 digital input points, providing a compact footprint for small sensor groups while matching typical byte boundaries in the PLC memory map.
The sensor interface can supply up to 0.5 A per channel from the internally routed US control voltage, removing the need for external power splitters. Field signals are daisy-chained downstream through one 4-pin M8 socket, while the primary power feed arrives through one 4-pin M8 connector. Both connections use M8 screw-in threads for vibration-resistant coupling. In the process image, the device occupies 8 input bits, so byte-aligned data can be transferred in one read cycle. Control and fieldbus isolation helps prevent ground loops between the sensor supply and the communication side. The module supports a variable installation position, and its signal connection uses the M8 screw-in format for convenient installation in modular production environments.
