Dwyer 25115 1/4 Inch Din Pid Temperature Controller

Product Description

The DWYER 25115 is a 1/4 inch DIN digital PID temperature controller designed for precise process temperature management in industrial and commercial HVAC, process control, and equipment monitoring applications. It accepts thermocouple inputs across five standard types, J, K, T, E, and N, and operates over a wide range up to 2500 degrees F. The dual 4-digit LCD display provides simultaneous readout of setpoint and measured temperature. Control output is a 4 to 20 mA isolated analog signal, making it compatible with a broad range of field devices and data acquisition systems. Accuracy is rated at 0.25 percent of span.

The 25115 is suited for residential and commercial process heating, industrial ovens, boiler control panels, and HVAC air handling equipment where reliable closed-loop temperature control is required. The PID control algorithm minimizes overshoot and steady-state error, making it appropriate for applications with tight process tolerances. The built-in alarm function supports process high and low limit monitoring. The universal voltage input range of 100 to 240 volts allows installation in both North American and international electrical systems without a separate transformer.

Compatibility

Designed as a standard 1/4 inch DIN panel-mount temperature controller compatible with thermocouple sensors of type J, K, T, E, and N in process control, HVAC, and industrial heating applications requiring a 4 to 20 mA analog output.

Installation Notes

Installation should be performed by a qualified electrician or instrumentation technician familiar with low-voltage control wiring and applicable NEC requirements. Disconnect and lock out all power to the control panel before wiring the controller. Verify thermocouple polarity and sensor type selection match the connected probe before energizing. Configure PID parameters and alarm setpoints during commissioning before placing the loop in automatic control.
