Dwyer 25025 Quarter Din Temperature Controller Rtd Pid

Product Description

The DWYER 25025 is a quarter-DIN digital temperature controller designed for industrial and commercial process control applications. It accepts an RTD sensor input and measures temperatures from -212 degrees C up to 2500 degrees F, making it suitable for high-temperature process environments. The controller uses PID control logic to regulate temperature output and delivers a 4 to 20 mA isolated analog output signal for integration with downstream control systems or data acquisition equipment. A dual 4-digit LCD display with dual 0.56-inch scale provides clear readout of process and setpoint values simultaneously. Licensed HVAC technicians, process control engineers, and industrial instrumentation specialists are the primary installers.

The DWYER 25025 is used in industrial process heating, commercial HVAC controls, and manufacturing environments where precise temperature regulation is required. The wide input voltage range of 100 to 240 volts makes it compatible with both domestic and international power configurations. Its quarter-DIN panel-mount form factor fits standard instrument cutouts commonly found in control panels and equipment enclosures. RTD sensor input suits applications where high accuracy and stability over a wide temperature span are priorities.

Compatibility

Designed as an OEM-style replacement or new-installation quarter-DIN temperature controller for industrial control panels and process equipment that use RTD sensors and accept a 4 to 20 mA control signal output.

Installation Notes

Installation should be performed by a qualified instrumentation technician or licensed electrician familiar with panel-mounted process controls. Disconnect and lock out all power to the control panel before mounting or wiring the controller. Follow applicable NEC guidelines for control wiring in industrial enclosures. Verify RTD sensor wiring configuration and signal loop connections before energizing the system.
