Dwyer Instruments 16B-33 Controller
The Dwyer Instruments 16B-33 Controller is a high-performance 1/16 DIN Temperature/Process Loop Controller designed for critical thermal management and process automation. Built for reliable industrial service, this model features a universal input that natively supports RTDs, thermocouples, and DC voltage/current process transmitters without the need for additional signal conditioners. The unit is equipped with dual relay outputs (Output 1 and Output 2), providing robust mechanical switching for contactors and solenoids in heating or cooling loops. Integrated RS-485 communication with Modbus ASCII/RTU protocol ensures seamless integration into PLC networks or SCADA systems for remote monitoring and data logging.
Operating on a flexible 100-240Vac power supply, the 16B-33 offers advanced control methods including PID control, On/Off, and manual tuning. Its front panel features dual 4-digit LED displays for simultaneous process value and setpoint indication, alongside an IP56 rating for protection against dust and moisture in harsh plant environments. The internal stage control program supports up to 64 ramp/soak actions, making it an ideal choice for complex oven profiling, environmental chambers, and boiler control applications where precision and multi-stage logic are required.
Key Benefits- Universal Compatibility: Configurable input accepts J, K, T, E, R, S, B, L, and U thermocouples, Pt100/JPt100 RTDs, and 0-20mA/4-20mA signals.
- Reliable Switching: Dual SPST relay outputs are rated for 3A at 250VAC, perfect for driving process loop hardware.
- Data Integration: Built-in RS-485 Modbus allows for 247 unique addresses and transmission speeds up to 38,400 bps.
- Precise Performance: High accuracy of ±0.25% span ensures tight temperature controller tolerances.
- User-Friendly Interface: Dual LED displays with selectable °F/°C and adjustable resolution for clear local diagnostics.
How do I wire a 4-20mA transmitter to the Dwyer 16B-33?
When using a DC current input, a 250-ohm precision resistor must be installed across the input terminals to convert the current to the appropriate voltage signal for the universal input.
Can this controller handle dual-loop cooling and heating?
Yes, the 16B-33 controller features two separate outputs which can be configured for direct or reverse acting control, allowing for simultaneous heat/cool management or auxiliary alarm signaling.
What is the maximum operating temperature for the unit itself?
The controller is designed to operate efficiently in ambient environments ranging from 32°F to 122°F (0°C to 50°C).
