Monitor and control temperature or process applications with precision. These self-tuning controllers offer many options to fit your application. Choose from 1/32-, 1/16-, 1/8- (vertical), and 1/4-DIN sizes.

Each controller has a dual LED that can display the following information: process value, set points, output status, engineering scale, auto tuning, and alarm status. Control methods include ON/OFF, PID, self-tune, and manual tune. PID control is supported only on the B-series with 64 ramp/soak control options. Two alarm outputs are standard on all models which can be quickly configured with the choice of thirteen built-in functions. With a standard built-in RS-485 interface these controllers can easily communicate with other external devices such as PCs and PLCs.

Models with output relay require snubber 89800-99 when connecting to an inductive load; order snubber separately.

    Comments about Dwyer 16B-33 Temperature Control, 1/16 DIN, Universal Input, Relay Outputs, Ramp/Soak:

    Unit is being used to control my heaters AND coolers on my 100gal marine aquarium. I have it in rate/proportional mode, (no integral). It reads 78.2F and keeps it within 0.3deg at all times. WORKS GREAT! There are relay's inside that control 3 fans and 2 heaters...
    6 months of continuous operations and I would highly recommend again.
