Atom DTU Cat1
Description
ATOM DTU CAT1 is a programmable LTE CAT1 Data Transfer Unit (DTU). Built-in SIM-A7680C module that adapts to LTE CAT1 frequency band in China, supports LTE-TDD/LTE-FDD wireless communication standard. Compared with NBIoT, CAT1 has stronger data transmission capability. The maximum downlink rate can reach 10Mbps (uplink)/5Mbps (downlink). The integrated SMA external antenna interface improves the communication quality and signal stability of the device. Different from the general DTU that only has the function of data transparent transmission, the ATOM DTU series adopts a more open architecture design. The controller ATOM LITE can modify the program at will according to the actual business. The whole machine reserves a variety of interfaces (RS485, I2C, custom interface) for users to expand, which is convenient for the quick access of sensors and actuators. With its own guide rail clamping structure, it is perfectly embedded in various industrial control sites. It is very suitable for application scenarios that require data transmission rate (remote control/data transparent transmission, etc).
