Detail:
This series of products is a new product which is developed by the latest single chip microcomputer technology. It can be matched with other temperature sensors such as thermocouple and thermal resistance, which can be used in combination with other DDZ-III and DDZ-II type electric units. Has been widely used in the industrial production process of the conversion of temperature signal.

The main features and functions of this series:
1, through the simple software and hardware settings, you can set the input index number, range, output signal type, etc., all set parameters can be permanently saved, and the power loss of data.
2, can take the isolated serial communication interface, the transmission rate can be set by the button, can be with a variety of input / output communication functions of the device for two-way communication, and form a network control system.
3, the setting parameters and debugging parameters can be used to lock the lock, the lock code can prevent the error operation
