Product Description:

The IE6002-0000 is an extension box unit produced by Beckhoff within the IE Extension Box Units series. It serves as a compact RS-232 interface node that brings serial communication to the machine level, allowing decentralized sensors, scanners, or identification devices to connect directly to the EtherCAT network without a control cabinet mount. By using screw-type M12 field wiring and integrated feed-through power, the module supports simple installation in distributed industrial automation layouts.

This model operates from a nominal supply of 24 V DC and draws only 40 mA, so multiple boxes can be daisy-chained without overloading standard auxiliary power segments. Serial traffic leaves the controller at a default rate of 9600 baud, which matches many legacy barcode readers and data recorders, although the rate can be adjusted when faster polling is needed. Communication follows the RS-232 electrical standard, and the device provides 2 data channels in the process image for serial data exchange. A 128-byte receive buffer helps smooth burst transmissions, while a 16-byte transmit buffer supports command queuing and helps keep latency predictable when host CPU tasks fluctuate.

Electrical insulation of 500 V helps protect the control electronics from ground loops when long cable runs or external equipment are present. The molded PA6 housing meets IP65/IP66/IP67, so the box resists dust ingress and high-pressure washdown on machinery frames. Overall dimensions are 30 x 126 x 26.5 mm, allowing the unit to mount beside pneumatic valves or I/O blocks with the provided 3.5 mm holes. Upstream and downstream M8 connectors support a maximum trunk length of 15 m, which covers most tooling plates and end-of-arm installations without repeaters.
