Monitoring Detection Unit - Linear Series

Description

Monitoring Distribution Units act as the backbone of XD, each receiving data from multiple in-line or parallel sensors and sending it back to the connected MCU. MDUs can be linked together to create a modular monitoring system at any shape or scale. Each MDU has an additional relay output to support PLC-enabled actions or serve as an added layer of redundancy.

Install one XD-LIN-MDU for each Linear sensor string that is needed. Connects to MCU via Ethernet, PoE Ethernet or RS-485. Each MDU can manage up to 3,200 feet of digital leak sense rope. Linear sensor circuits include precision leak distance location on each rope segment and support up to 5 branching paths per MDU. All downstream sensors are powered by the MDU, no local power supplies or batteries are required.

Technical resources for this product are to be released shortly.
