RS232/RS485 Converter

Efficient and good quality analog to RS485 converter supports 7-channel signal acquisition and conversion, able to flexibly handle 4-20mA and 0~5V input signals, adopts ModBus-RTU communication protocol, supports bidirectional independent communication, easy to be integrated with existing systems.

ATO high quality RS485 converter for sale allows users to accurately convert 4-20mA or 0-5V signals to RS485 digital signals with 8 independent channels, which is suitable for multi-point real-time monitoring. Powerful ModBus-RTU protocol support and a variety of adjustable communication parameters make it ideal for industrial automation.

The 4-20mA to RS485 converter module can collect up to 2 channels of analog signals (4-20mA, 0-10V, 0-5V) and upload them to 485 interface standard ModBus-RTU communication protocol. 485 interface up to 2000 meters, can be directly accessed to the site of the PLC, industrial control instrumentation, configuration screen or configuration software.

This 4-channel signal converter is designed for industrial applications and outputs via RS485 interface with ModBus-RTU communication protocol for compatibility and wide adaptability. It supports the acquisition of 4-20mA, 05V, 010V signals optionally, and provides up to 12-bit AD resolution to ensure high accuracy of data acquisition.
