Dwyer 25012 1/4 in Din Temperature Controller 2500F

Product Description

The DWYER 25012 is a 1/4 inch DIN digital temperature controller designed for precise process temperature control in industrial and commercial HVAC, manufacturing, and process control applications. It accepts thermocouple inputs of types J, K, T, E, and N, covering a measurement range down to -212 degrees C and up to 2500 degrees F. The controller uses a PID control algorithm to maintain setpoint accuracy and features a dual 4-digit LCD display for simultaneous readout of process value and setpoint. It operates on a wide supply voltage range of 100 to 240 volts, making it suitable for both domestic and international electrical systems. Installation is handled by qualified technicians familiar with low-voltage control wiring and process instrumentation.

The DWYER 25012 fits into standard 1/4 inch DIN panel cutouts, making it a practical drop-in option for control panels in industrial process lines, HVAC air handling systems, furnace and oven temperature monitoring setups, and laboratory equipment enclosures. Its broad thermocouple input compatibility means it can be deployed across a wide variety of sensing environments without requiring a separate transmitter. The dual-scale LCD display supports readout in both Fahrenheit and Celsius, reducing the need for manual conversion on mixed-unit job sites.

Installation Notes

Installation should be performed by a qualified instrumentation or controls technician familiar with panel-mounted process controllers. De-energize the control panel completely before wiring or removing an existing controller. Follow the NEC and applicable local codes for low-voltage control circuit wiring. Verify thermocouple type and polarity match the controller input setting before applying power.
