Trane Technologies S3090054062 Controller Module

The Trane Technologies S3090054062 Tracer MP501 controller module is a configurable direct digital controller (DDC) designed to provide precise HVAC control within Trane building automation systems, including air handling units, terminal units, heat pumps, and rooftop systems. It can operate as a standalone controller or as part of a LonTalk® Comm5 network, delivering reliable monitoring, control, and communication for commercial HVAC applications. Key specifications include 24 VAC nominal power (21–27 VAC) at 50/60 Hz, with a typical power consumption of 10 VA (70 VA maximum), and support for two-stage, tri-state modulating, and 0–10 VDC analog outputs to execute heating, cooling, ventilation, and equipment sequencing. The module is mounted panel‑mount for OEM replacement and is configurable via the Trane Rover Service Tool or compatible EIA/CEA-860 service tools, suitable for use with Trane air handling units, heat pumps, rooftop units, and terminal units in commercial buildings. Common replacements include the MP501, MP503, UC400, and UC600 controllers, reflecting its role as a compatible, expandable control module within Trane building automation and energy management systems for industrial facilities.
