Dwyer 26050 Quarter Din Temperature Process Controller

Product Description

The DWYER 26050 is a 1/4 DIN digital temperature and process controller designed for industrial and commercial HVAC, process control, and building automation applications. It accepts a universal sensor input, covering a wide range of thermocouple and RTD types, and controls output via a fuzzy logic PID algorithm for precise and stable temperature regulation. The unit operates on 100 to 240 volts, making it compatible with standard single-phase power in North American and international installations. A dual 4-digit LCD display with 0.56-inch scale provides clear readout of process and setpoint values simultaneously. Licensed technicians and controls specialists are the typical installers of this device.

The DWYER 26050 suits residential, light commercial, and industrial process applications where accurate temperature or process variable control is required. It fits into a standard 1/4 DIN panel cutout, making it a straightforward replacement or upgrade in existing control panel builds. The 0 to 20 mA isolated analog output allows integration with PLCs, data loggers, and building automation systems. Its universal sensor input eliminates the need to stock sensor-type-specific controllers, simplifying field inventory for service contractors and panel builders.

Key Features

• Universal sensor input supports multiple thermocouple and RTD types in a single unit
• Fuzzy logic PID control for stable, responsive temperature and process regulation
• Wide operating voltage range: 100 to 240 volts AC for flexible installation
• Dual 4-digit LCD display shows process value and setpoint simultaneously
• 0 to 20 mA isolated analog output for integration with external control systems
• Standard 1/4 DIN form factor for straightforward panel mounting

Compatibility

Designed as an OEM-style replacement or upgrade for standard 1/4 DIN panel-mount temperature and process controller cutouts in industrial and commercial control panels.

Installation Notes

Installation of panel-mount process controllers should be performed by a qualified controls technician or licensed electrician in accordance with the NEC and applicable local codes. De-energize the control panel completely before wiring or mounting the unit. Verify sensor type and wiring configuration match controller input settings before applying power. Do not exceed the rated voltage range when connecting line power.
