NetGuardian 480

The Low-Cost, Easy-to-Implement Solution to Monitoring

The NetGuardian 480 is a specialized member of the NetGuardian family, optimized for use as a high-capacity discreteonly responder. The result is a highly cost-effective solution for gathering the diverse equipment at your remote site and integrating it into a single modern network management system.

With 80 discrete alarm inputs - 2½ times as many as the NetGuardian 832A- you can easily forward all the alarms of a small to medium-sized site. This dense alarm coverage gives you the convenience of a single-box solution, saves you the cost of buying multiple low-capacity RTUs, and offers you the lowest possible cost per point.
