Description
Product Description
The Foxboro DM900NY is a high-performance expansion output module designed for the Foxboro I/A Series Distributed Control System (DCS). It extends controller output capacity by providing additional analog and discrete points, allowing precise management of field devices such as valves, actuators, alarms, and recorders.
Built for demanding industrial environments, the DM900NY supports high-voltage 120 VDC outputs, peak output power up to 500 W, and Modbus‑RTU communication over RS‑485. Its rugged enclosure and wide operating temperature range ensure reliable performance in chemical, power generation, pharmaceutical, and oil & gas applications.
The module is designed for fast switching, seamless rack integration, and long-term reliability, with IP65/IP67 protection against dust, moisture, and vibration.
