Industrial IS002RE Bus Extender Interface Module

Industrial IS002RE Bus Extender Interface Module from United Technologies Carrier is a compact circuit-board interface designed to extend a Carrier DCS bus inside an industrial control cabinet. The part number IS002/RE is accompanied by an enclosure and provides the wiring connections and switch-block settings needed to configure the extended bus interface. In distributor catalogs, it is listed specifically as a Bus Extender within the DCS Module/Board/Rack family, underscoring its role as an ancillary interface rather than a primary control device. The IS002RE is designated discontinued by the manufacturer, a status that affects availability, compatibility with legacy Carrier equipment, and long-term maintenance planning. With a weight of 1.60 lb, the unit offers a relatively light footprint suitable for mounting in standard control panels alongside other Carrier DCS components. This module represents Carrier’s historical approach to expanding bus reach in industrial automation, delivering a targeted extension solution without requiring overhaul of the central controller.
