Custom Design Open architecture enables the WatchMan500 to accept virtually any sensor or telemetry. Expandability to up to 28 modules allows hundreds of potential sensors to be connected to one system in a single NEMA 4 enclosure with a single communications link and power source.

WATCHMAN500 Core Technology The WatchMan500™ node is an intelligent, configurable and expandable sensor I/O controller and datalogger with two-way communications, designed for long-term operations in any location or environment. This platform is the ideal solution for any application requiring data collection, control, processing, or remote system management. It can interface with custom or off-the-shelf sensor equipment, software and telemetry.

The unique infrastructure of the WatchMan500TM node allows additional I/O to be added by interconnecting multiple modules. Any one of these modules can be designated the “primary module” and enables the system to be remotely queried and configured. This primary module processes then forwards the data over a chosen communication link to a pre-designated data center.

The WatchMan500TM node has been successfully integrated into environment monitoring systems and operational networks worldwide.
