Environment Monitoring Sensors Manufacturer
analog to rs485 converter can be achieved between the sensor and the host signal acquisition, used to detect analog signals. Application in the 485 bus industrial automation and control systems, can monitor 4 ~ 20mA / 0 ~ 5V / 0 ~ 10V signal. Safe, reliable, beautiful appearance, easy installation.
analog to rs485 converter using the standard Modbus-RTU protocol, address, baud rate can be set by the host computer software that can be articulated in the 485 bus. Products according to industry-standard design, manufacture, with over-voltage protection, over-current protection, anti-interference ability, high reliability.

The conversion module only needs one end of the power supply to be able to work normally, and the other end of the power supply is prepared for the subsequent stage power supply. If the latter stage is not powered, it can be left floating.
When multiple 485 models are connected to the same bus, there are certain requirements for on-site wiring, please contact us for details.
