RS4 22 serial server ZLAN51 43-422 is a high-reliability, high-performance serial server / Modbus gateway product specially designed for anti-lightning, anti-electromagnetic interference and anti-harsh environment requirements . It is the flagship product of serial server. It can be applied to industrial applications that require anti-interference and anti-lightning strikes such as tunnel monitoring, wind power generation, and field geological disaster monitoring.
ZLAN5143I-422 has good interface isolation characteristics. Its RS485 / RS422 not only has positive and negative 15KV anti-static interference, but also has 2500V interface isolation, that is , 2500V AC voltage is added between the RS485 line and the housing , and the leakage current to the internal current of ZLAN5143I-422 is less than 5mA . In order to solve the problem of burning the serial server through the lightning strike of the power supply , ZLAN5143I-422 isolates the power supply and adopts a 3000V isolated power supply. That is, 3000V AC is added to the input power line and the casing , and the leakage current to the internal current of ZLAN5143I-422 is less than 5mA . The isolation has been rigorously tested. Provide the shell ground terminal, which can release the lightning current to the ground and protect the product.
The RS485 of ZLAN5143I-422 has the ability to drive 256 loads. Compared with the product that drives 32 loads, it can realize more equipment data monitoring capabilities and save costs. ZLAN5143I-422 has three interface forms of RS232 / 485/422 . The input voltage can provide DC Q2.1 jacks or terminal blocks, and the input voltage is 18 ~ 36V ( 12V products can also be customized ). Can be equipped with rail mounting accessories.
ZLAN5143I-422 not only has the data transparent transmission function from TCP to RS232 / 485/422 , but also has the function of storage Modbus gateway. The storage type refers to that the 5143I can automatically collect and store the data of the Modbus RTU device. The data collected by the network port is directly read from the 5143I , which greatly speeds up the data collection speed of the network port.
