Dwyer 26133 Quarter Din Temperature Process Controller

Product Description

The DWYER 26133 is a quarter DIN temperature and process controller designed for precise setpoint control in demanding industrial and commercial HVAC applications. It accepts a universal sensor input, making it compatible with a wide range of thermocouples and RTDs without requiring a dedicated input module. The controller operates on 100 to 240 volts AC, features fuzzy logic PID control for stable and responsive temperature regulation, and displays readings on a dual 4-digit LCD with a 0.56-inch scale. A built-in alarm output and mechanical relay output round out the core functionality. Licensed HVAC technicians and industrial controls specialists are the typical installers.

This controller fits quarter DIN panel cutouts and is suited for residential and light commercial process control panels, boiler management systems, industrial ovens, and temperature monitoring stations. It handles a measurement range extending up to 4208 degrees F, making it applicable across low- and high-temperature process environments. The universal sensor input reduces stocking complexity by accommodating multiple sensor types within a single unit. Where a compact, panel-mount temperature controller with PID and alarm capability is required, the 26133 is a direct-fit solution.

Key Features

• Universal sensor input accepts multiple thermocouple and RTD types
• Fuzzy logic PID control for accurate and stable temperature regulation
• Dual 4-digit LCD display with 0.56-inch digit scale for easy readback
• Wide supply voltage range: 100 to 240 volts AC
• Integrated alarm output for setpoint deviation notification
• Mechanical relay output for direct load or external device switching

Compatibility

Designed as an OEM-style replacement or new-installation controller for quarter DIN panel cutouts in temperature and process control applications requiring universal sensor input.

Installation Notes

Installation should be performed by a qualified controls technician or licensed electrician familiar with NEC panel wiring requirements. Power down the control panel completely before wiring or removing an existing controller. Verify sensor type and wiring polarity before energizing to avoid input errors or sensor damage. Consult the manufacturer wiring diagram for relay output and alarm terminal assignments prior to commissioning.
