1-Wire RS422 RS485 Gateway ADA-401WP

The ADA-401WP module is a Gateway designed to acquire 1-Wire sensors and make them available on a RS422 (or RS485) network with ModBus RTU protocol.

The use of 1-Wire digital sensors eliminates the influence of cable length on the measurement process that is normally present in analog methods of measuring temperature, humidity or pressure. The digital sensors transmit the measured value via data transfer protocol and this simplifies wiring, allows the connection of a large number of sensors on the same bus and improves the detection of defective components.

The Gateway 1-Wire RS422 RS485 ADA-401WP makes it possible to use 1-Wire sensors in industrial environments. ADA-401WP is robust, has a modular design and allows 1-Wire sensors to operate in industrial control environments.
Using the ADA-401WP as an addressable 1-Wire bus node allows you to extend the distance up to 1200 m between the 1-Wire devices and the PC (with monitoring software) or other devices of type Master (e.g. PLC).

The ADA-401WP device allows low power supply in a range from 10 to 30Vdc and is equipped with reverse polarity protection.
