IE2022 by Beckhoff

The IE2022 is an output extension module built by Beckhoff and assigned to the IE Extension Box Units series. Designed as a field-mountable IP interface for decentralized I/O, the device provides eight digital outputs so machine controllers can drive actuators directly on the production floor without requiring additional enclosure space. By placing switching electronics close to sensors and loads, the module shortens wiring runs and simplifies the expansion of EtherCAT or other Beckhoff control architectures.

Each of the eight digital channels operates at a nominal bus level of 24 VDC. Field wiring leaves the block through an M12 screw-in port, and the network extends through a 1 x M8 socket with 4 pins at the downstream end. Internal electronics draw only 30 mA, keeping most of the supply available for connected loads. The module can switch up to 2.0 A per channel, and the PLC exchanges an 8-bit output process image. Control and fieldbus isolation separates the logic circuits from the power circuits, while reverse-polarity protection guards against wiring errors. The outputs support resistive, inductive, and lamp loads. Feed and power supply connections use identical M8, 4-pin male connectors, and freewheeling paths manage energy from inductive loads during switching.

The housing meets IP65/IP66/IP67 protection ratings, allowing exposure to washdown water or coolant spray when all connections are properly secured. The variable installation position allows the module to be mounted in the orientation required by the machine layout. Output status is shown by dedicated LEDs located beside each channel, allowing faults and switching states to be viewed without opening a cover. The unit is short-circuit-proof and limits fault current to 4.0 A. The sensor rails provide up to 0.5 A, while the total load current must remain below a 4 A maximum. Internal monitoring helps protect the outputs during excessive current demand and supports appropriate upstream circuit protection. Automatic recovery after overcurrent events supports continuous operation in conveyors, grippers, and valve manifolds that require reliable digital switching.
