Dwyer 25011 Quarter Din Pid Temperature Controller

Product Description

The DWYER 25011 is a 1/4 DIN digital PID temperature controller designed for precise process temperature management in industrial and commercial applications. It accepts multiple thermocouple input types including J, K, T, E, and N, with a measurement range reaching up to 2,500 degrees F. The controller features a dual 4-digit LCD display with a 0.56-inch scale on each readout, allowing simultaneous monitoring of setpoint and process temperature. Output is via solid-state relay (SSR) drive. The unit operates across a wide supply voltage range of 100 to 240 volts AC. Licensed HVAC technicians, process control technicians, and industrial electricians are the primary installers.

The DWYER 25011 is suited for residential and light commercial heating systems, industrial ovens, kilns, plastic processing equipment, laboratory equipment, and any process requiring closed-loop PID temperature control. Its 1/4 DIN form factor fits standard panel cutouts, making it a common choice for control panel builds and retrofit applications where multiple thermocouple input types must be accommodated on a single platform.

Key Features

• PID control algorithm for stable, accurate process temperature regulation
• Accepts thermocouple types J, K, T, E, and N for broad sensor compatibility
• Temperature range up to 2,500 degrees F for high-heat process applications
• Dual 4-digit LCD display with 0.56-inch digit scale for clear simultaneous setpoint and process readout
• SSR output for solid-state switching without mechanical relay wear
• Wide input voltage range of 100 to 240 volts AC for use across standard power systems
• Standard 1/4 DIN panel-mount form factor

Compatibility

Designed for use with thermocouple types J, K, T, E, and N sensors. Fits standard 1/4 DIN panel cutouts and is suitable as an OEM-style or retrofit temperature controller in process control panels and industrial equipment enclosures.

Installation Notes

Installation should be performed by a qualified electrician or instrumentation technician in accordance with applicable NEC requirements. Disconnect and lock out all power to the control panel before wiring the controller, sensor input leads, and SSR output connections. Verify that the thermocouple type is configured to match the sensor installed in the process. Do not apply power until all wiring connections have been inspected and the panel enclosure is properly closed.
