Request InformationAll Products

Honeywell Digital Controllers cover the DC1000, UDC700, UDC1200/UDC1700, UDC2500, UDC3200, and UDC3500 families — microprocessor-based PID and ON/OFF controllers available from 1/32 DIN to 1/4 DIN form factors. They accept universal analog inputs (thermocouple, RTD, linear voltage and current) and are applied to temperature, pressure, and level control across furnaces, ovens, environmental chambers, plastics processing, and packaging machinery.
