Sometimes, the customer’s sensor is an analog interface, but the data transmission device is an RS485 interface, and the server requires RS485 data. In this case, you can use our company’s analog to 485 module, ZHT0062 product.
This product provides 6 channels of AI, 2 channels of AO and 1 channel of RS485 interfaces. Supports standard Modbus RTU protocol, supports 4~20mA analog input/output, and supports 12-bit sampling accuracy. Note: This product does not have a built-in transmission module and only has the function of converting analog quantities to RS485.
Customers can choose this product when the sensor is an analog interface and the transmission device is an RS485 interface.

Let’s talk about another situation. The customer’s sensor is an analog quantity, but the server needs RS485 data, which needs to be transmitted to the server through the 4G network. In this case, this product is suitable – ZHC4661.
ZHC4661 is an industrial grade 4G RTU. The network is 4G full network. It provides 4 channels of AI, 2 channels of AO and 1 channel of RS485 interfaces. It supports Modbus RTU/TCP adaptive, automatic acquisition and active reporting, 4~20mA analog control acquisition, It has special functions such as automatic calibration threshold reporting, supports one-to-one and many-to-one networks, and visualizes the configuration software interface window to enable users to connect, debug, and configure equipment on-site or remotely. It can be widely used in power systems.
