DTB4848VV Advanced Temperature Controllers

The DTB4848VV is a Delta advanced temperature controller with a linear voltage control output and dual circuit control output. Compared with the DTA series, the DTB series adds a linear voltage control signal output, and adopts a double circuit output control, which can perform heating and cooling control at the same time in the temperature control system to achieve the system’s rapid response to the set temperature requirements.

In addition, the DTB4848VV has 64 programming functions, which can set 64 different sets of temperature and control time. At the same time, it also has 485 communication and 3 alarms.

In terms of application, DTB4848VV is widely used in central air conditioning fan coil system, HVAC heating system, etc., showing its efficiency and stability in practical applications.

485 communication is a serial communication protocol, also known as RS-485. It is a communication standard developed by the Electronic Industry Association (EA) to solve the problems of short serial communication distance, low communication rate, and weak interference resistance. 485 communication protocol using air division signal transmission mode, with strong anti-interference ability, communication distance, high communication rate advantages, so widely used in industrial automation, security monitoring, smart home and other fields. In addition, it also supports a variety of physical layer interfaces, including twisted pair, coaxial cable, fiber, and so on.

3 Alarm functions are usually associated with alarm systems and are used to issue alarms in different situations. In the event of a possible air attack on the city, advance warning signals will inform citizens to prepare for air attacks in advance. Air raid warning signals will further alert people when air strikes are about to take place or have already begun. The purpose of these alarm functions is to protect people’s life and property safety.
