Built on the legacy of Honeywell's field-proven UDC family, the Honeywell UDC2500 digital controller introduces new features in the popular low-priced 1/4 DIN size while retaining the reliability, cost-effectiveness, simplicity, and popular interface of Honeywell's UDC2300 controller.
Like the UDC2300, the UDC2500 monitors and controls temperature, pressure, flow, level, and other process variables.
