Temperature measurement resolution: 9~12 bits (0.0625 degrees Celsius).
Temperature measurement speed: > 40 points /s;
Support for measuring cable length: less than 200M;
Support sensors in two-wire or three wire connection mode;
Automatically identify the number of sensors, ID automatic sorting.
12V/24V/48V input (external, optional).
Module operating temperature: -25 ~ 85 DEG C.
The module adopts the latest technology, supports the American DALLAS series of 1-wire bus digital temperature sensors, and supports "two lines" or "three lines" in two ways, so that users are more convenient to use. Each module can connect seven temperature measuring cables, each cable can be installed up to 64 temperature points. The module automatically detects the number of sensors, and the ID automatically sorts. Real time refresh data buffer.
