4-Channel 485 Data Acquisition Instrument can be used in conjunction with various sensors and transmitters. It enables cyclic inspection, alarm control, transmission output, data acquisition, and communication for multiple industrial process parameters such as temperature, pressure, liquid level, flow rate, weight, current, and voltage.
Adopting electronic technology, it is centered on high-speed signal processors and microprocessors, featuring a digital design for enhanced intelligence.
Equipped with an opto-isolated RS-485 communication interface, it adopts the ModBus RTU communication protocol. The circuit design implements three-terminal isolation for input, power supply, and output.
