Dwyer 25015 Quarter Din Pid Temperature Controller

Product Description

The DWYER 25015 is a quarter DIN digital temperature controller designed for precise process temperature management in industrial and commercial HVAC, laboratory, and manufacturing applications. It accepts thermocouple inputs of types J, K, T, E, and N, and delivers a 4 to 20 mA isolated analog output for integration with downstream control systems or recorders. Operating on a wide supply voltage range of 100 to 240 volts, this PID controller uses proportional-integral-derivative logic to minimize temperature overshoot and maintain setpoint accuracy. A dual 4-digit LCD display at 0.56 inch scale provides simultaneous readout of process value and setpoint. The unit weighs 0.75 pounds and fits standard quarter DIN panel cutouts.

The DWYER 25015 is suited for residential and light commercial HVAC systems, process heating and cooling equipment, kilns, ovens, and environmental chambers where tight temperature control is required. Its broad thermocouple compatibility makes it a practical replacement or upgrade controller in existing panel installations where sensor type may vary across equipment. Licensed HVAC technicians, industrial controls technicians, and instrumentation professionals are the primary installers for this device. No alarm output is included in this configuration, making it appropriate for straightforward single-loop control loops that feed alarms externally.

Key Features

• PID control algorithm minimizes overshoot and setpoint deviation
• Accepts five thermocouple input types: J, K, T, E, and N
• Wide operating voltage range: 100 to 240 volts AC
• 4 to 20 mA isolated analog output for compatibility with recorders and PLCs
• Dual 4-digit LCD display shows process value and setpoint simultaneously at 0.56 inch scale
• Temperature range up to 2500 degrees F (-212 degrees C minimum)

Compatibility

Designed as an OEM-style replacement or new-install quarter DIN temperature controller for single-loop process control panels accepting thermocouple sensor inputs of types J, K, T, E, or N with a 4 to 20 mA analog output requirement.

Installation Notes

Installation should be performed by a licensed instrumentation technician or controls electrician familiar with low-voltage panel wiring and applicable NEC requirements. De-energize the control panel completely before mounting or wiring the controller. Verify that the thermocouple type and range configured in the controller match the installed sensor before powering the loop. Do not exceed the rated supply voltage range of 100 to 240 volts AC.
