Dwyer 32A022 Temperature Process Control 4208F 1/32 Din

Product Description

The DWYER 32A022 is a 1/32 DIN digital temperature and process controller designed for precise closed-loop control in HVAC, industrial, and process applications. It accepts a universal sensor input, allowing compatibility with a broad range of thermocouple and RTD types without requiring a dedicated input module. The controller operates on a supply voltage range of 100 to 240 volts AC, making it suitable for both domestic and international installations. A dual 4-digit LCD display provides simultaneous readout of process value and setpoint, and the fuzzy logic PID control algorithm continuously adjusts output to minimize overshoot and setpoint deviation. The unit measures temperature up to 4208 degrees F, covering the demands of high-temperature process monitoring.

The DWYER 32A022 fits residential and light commercial HVAC control panels, boiler management systems, and industrial process skids where a compact DIN-rail or panel-mount controller is required. Its 1/32 DIN form factor makes it a practical choice for high-density control panels where space is limited. Licensed HVAC technicians, instrumentation technicians, and controls engineers are the primary installers. The universal sensor input reduces the need to stock multiple controller variants for different sensor types across a facility or service fleet.

Key Features

• Universal sensor input accepts multiple thermocouple and RTD types without hardware changes
• Fuzzy logic PID control reduces overshoot and improves setpoint stability
• Dual 4-digit LCD displays process value and setpoint simultaneously
• Wide supply voltage range of 100 to 240 volts AC supports domestic and international use
• 1/32 DIN panel-mount form factor for compact, high-density control installations
• Temperature range extends to 4208 degrees F, suitable for high-temperature process environments

Compatibility

Designed as an OEM-style replacement or new-installation controller for 1/32 DIN panel cutouts in temperature and process control applications accepting a universal sensor input.

Installation Notes

Installation should be performed by a qualified instrumentation technician or licensed HVAC controls professional. De-energize the control panel and verify the absence of voltage before wiring the controller. Sensor wiring should be routed separately from power conductors to minimize electrical noise interference with the analog input signal. Follow local electrical codes and the NEC for proper panel wiring practices and overcurrent protection.
