VIP+ Elecyss pipeline watchdog. The Watchdog VIP+ is a 4-channel monitoring device that offers the configuration flexibility necessary for rectifier sites requiring additional current return monitoring or basic monitoring applications at dual rectifier sites.




 Units come factory configured as Ch 1 – volts, Ch 2 – amps, Ch 3– pipe to soil potential (required reference cell not included) and Ch 4– 0-50 Vdc. In addition, the units are equipped with an AC detection probe to measure the presence of AC power to the rectifier and a dry-contact digital input. Each analog channel can be configured for any of the available input voltage ranges.

Using field-proven Watchdog lightning surge-resistant circuitry, the Watchdog VIP is the best choice for cost-effective CP rectifier monitoring on pipelines, well casings, bridge decks, and piers.
