UDC 2500


UDC2500 Limit Controllers accept input signals from any of several types of external sensors such as Thermocouples (T/Cs) and Resistance Temperature Detectors (RTDs). It conditions these signals, as necessary, to derive the equivalent Process Variable (PV) value that drives various circuits in the controller.

The equivalent PV signal is compared with the Limit control set point and any error signal from the differential amplifier de-energizes the coil of an electromechanical, single-pole, dual-throw (SPDT) limit output relay.

When de-energized, the output relay “Locks Out” and remains that way until the PV input signal drops below the High Limit Set Point or goes above the Low Limit Set Point and the controller is reset manually via the keyboard or from a remote location (Contact Input Option).

The contact of the output relay terminates at the rear terminal of the controller to which you make the appropriate field wiring connections. A flashing “LIMIT” in the lower display indicates that the output relay is de-energized.
