Why Choose Bullhorn RM510 16-Channel Rectifier RMU Expansion Module
Elevate your cathodic protection monitoring with the Bullhorn 16-Channel Expansion Module. Designed to integrate seamlessly with your existing Bullhorn RM510 rectifier remote monitors, this module transforms your standard remote monitor into a high-density data hub.
- 16 differential analog channels for high-density monitoring
- DC voltage range of +/- 150Vdc
- Surge immunity up to 30kV (300ms transients)
- Channel-to-channel isolation of 250V (DC or AC)
- Compact form factor fits inside NEMA 4 enclosures or rectifier cabinets
- Seamless integration with existing Bullhorn RM510 units
- Powered directly by the RM510 host unit
- Backed by American Innovations’ standard 3-year warranty
THE EXPANDED MONITORING SOLUTION
Engineered to solve complex survey site challenges without the need for multiple remote monitoring units—the 16-Channel Expansion Module expands your existing Bullhorn RM510 rectifier unit from 4 channels to 16 differential analog channels. Monitor multiple assets, additional negatives, and complex junction boxes from a single, compact device.
COMPREHENSIVE DATA FOR COMPLEX SITES
Designed for high-density applications like a tank farms and multi-lead junction boxes, the Expansion Module ensures you capture every critical data point. It eliminates manual bi-monthly check on additional assets, streamlines your compliance workflow and reduces site visits. It fits inside a standard rectifier cabinet or NEMA enclosure, delivering massive capability in a discrete package.
SEAMLESS FIELD INTEGRATION
This module is built for easy deployment. It utilizes your RM510 for power. Simply upgrade the RM510 firmware using the Bullhorn FieldPro mobile application and wire the I/O expansion module to your RM510 analog input module.
