Dwyer 16A2151 Temperature Process Control 1/16 Din

Product Description

The DWYER 16A2151 is a 1/16 DIN digital temperature and process controller designed for precision thermal management in industrial and commercial HVAC, process heating, and building automation applications. It accepts a universal sensor input, making it compatible with a wide range of thermocouple and RTD sensor types without requiring a dedicated input module. The controller operates on 100 to 240 volts AC and uses fuzzy logic PID control to maintain accurate setpoint regulation up to 4,208 degrees F. Output is via AC solid-state relay (SSR) drive. A dual 4-digit LCD display provides simultaneous readout of process value and setpoint.

This controller fits installations where a compact 1/16 DIN panel-mount footprint is required. Typical applications include process heating systems, industrial ovens, HVAC air handling units with precise temperature control requirements, and laboratory or light manufacturing environments. The universal sensor input supports flexible job-site configuration. Licensed electricians, controls technicians, and HVAC controls specialists are the primary installers for this type of device.

Compatibility

Designed as an OEM-style panel-mount replacement or new-installation temperature process controller for 1/16 DIN cutout enclosures in industrial, commercial, and HVAC control panel applications.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician in accordance with NEC requirements for panel-mounted control devices. De-energize the control panel and verify absence of voltage before wiring the controller. Verify sensor type and wiring polarity before applying power, as incorrect sensor wiring can result in erroneous readings or controller fault conditions. Follow the manufacturer wiring diagram for SSR output connections.
