Omron E5AN-C3QMT-500-N Temperature Controller

The Omron E5AN-C3QMT-500-N Digital Temperature Controller is a panel-mounted PID controller used in industrial temperature control systems. It accepts universal input (thermocouple, RTD, or analog) and supports both PID and ON/OFF control, operating from 100–240 V AC. The 96 × 96 mm (1/4 DIN) display shows PV and SV with auto-tuning, alarms, and a preventive maintenance feature to simplify daily operation. Key accuracy specs are ±0.3% for TC inputs, ±0.2% for RTD inputs, and ±0.2% FS for analog signals, with a sampling period of approximately 250 ms. Common applications include control panels, ovens, plastic molding machines, furnaces, packaging equipment, and other process heating setups that require stable, reliable temperature regulation and robust sensor input handling. The front panel is IP66-rated for demanding environments, and the unit is part of the E5AN series; note that this model is discontinued and replaced by the E5CC/E5EC series. Typical replacements include Omron E5CC-QX2ASM-800, E5EC-QX2ASM-800, and E5EN-C3QMT-500-N for retrofit or migration. This device is well suited for OEMs, system integrators, and maintenance teams seeking precise temperature monitoring and control in automated processes.
