Product Description:

The IE2022 extension box is a digital output module manufactured by Beckhoff for the IE Extension Box Units series. It serves as a remote I/O node that places protected 24 V switching capability directly on a machine frame, minimizing control-cabinet wiring. In an industrial automation system, it routes PLC commands to field actuators and supports compact installation in harsh areas with its sealed metal housing. The unit interfaces with EtherCAT or other backplane couplers through a single cordset and acts solely on output bits.

Operation is based on a nominal supply of 24 VDC, aligning with the standard control power found in most machinery. The module provides 8 digital sourcing outputs presented to the controller as an 8-bit process image, so every channel can be addressed individually. Each channel can deliver up to 2.0 A, allowing direct switching of solenoid valves, signal lamps, or small motors, while the box may draw a maximum of 4 A through its supply line. The electronics support resistive, inductive, or lamp loads and remain functional after fault events because the outputs are short-circuit-proof. A protection rating of IP65/IP66/IP67 permits mounting on moving tooling without an additional enclosure. Reverse-polarity protection prevents damage if the input supply is accidentally wired backward.

Electrical safety and network reliability are supported by control-to-fieldbus isolation, which keeps switching noise away from the logic bus. Supply power enters through a 4-pin feed connector and is forwarded to additional modules through the 1 × M8 socket with 4 pins, supporting daisy-chain layouts on the machine. Actuator leads terminate at the M12 screw-in ports, and the device can also provide auxiliary power of up to 0.5 A per channel. Power distribution and signal switching are housed in the same enclosure, simplifying installation and grounding across movable assemblies.
