The new DTD series temperature controllers are easy to operate; the reduced number of keys makes the operation of DTD easier to maneuver and control. The new controller offers a pattern of programmable PID 8-step control method, making the temperature in the production process more variable. DTD offers relay and voltage pulse outputs and at the same time a group of alarm outputs with multiple modes remain available. Additionally, the DTD series is equipped with an analog input function. Complying with IP66 waterproof standard, the DTD series is suitable for all kinds of application in different fields, and is the most competitive temperature controller in the market.
