This is an 8-channel single-end 12-bit analog data acquisition module with an accuracy of up to ±1‰, supporting 0-5V, 1-5V, 0-2.5V, 0-20mA, 4-20mA ranges. It can collect multiple channels simultaneously, and can also collect voltage and current at the same time. The module RS485 communication interface has optoelectronic isolation, and the application layer adopts the standard Modbus RTU protocol, which conforms to industrial standards. It can be conveniently used to communicate with the host computer. You can use this module to realize rapid networking, build a monitoring system, or connect with PLC, configuration software, Industrial Personal Computer, OPC, and other systems.

Each channel of the module is independent, which can set the range independently. There are a variety of ranges to choose from, and users can switch them at will according to their needs. In addition to supporting standard 4-wire sensors, it also supports 2-wire and 3-wire sensor inputs.

Security is extremely guaranteed. The product has communication isolation and input/output isolation, so that it can not only resist interference during use, ensure accurate and stable data transmission, but also in case of strong electricity, it will only burn out the collection product at most and the entire system will not be damaged. The module supports a 12-30V wide voltage power supply, and the interface adopts an anti-reverse design.
