ZIO-CPM Cathodic Protection Monitor
ZIO-CPM is designed to measure critical CP parameters such as Structure to Reference, Foreign Structure to Reference and Instant Off potentials automatically.
ZIO-CPM offers multi-function 4-20mA outputs and RS485 MODBUS scada connection for monitoring the parameters measured at the programmable intervals.
Wide input voltage range allows ZIO-CPM to be powered with 12-50 VDC. Reverse polarity protection assures modules connection safety. ZIO-CPM also offers 4 Digital Inputs for general purpose usage.
