12 is an insulation fault locator designed to work with the ISOM AMD322 controller. Together, they provide continuous monitoring and selective fault location for unearthed/isolated power systems (IT systems), frequently used in medical facilities, operating theaters, and industrial environments.Core CapabilitiesMulti-Channel Tracking: Tracks up to 12 measuring channels/circuits simultaneously by detecting the test current.Selective Fault Finding: Pinpoints which specific branch or sub-circuit is experiencing an earth/insulation fault, while keeping the system running for high-availability needs.Alarm Signaling: Uses front-panel channel LEDs, an overall alarm LED, and an alarm output relay to immediately flag faulty sub-circuits.Direct Compatibility: Acts as a master unit communicating directly with the ISOM AMD322 permanent insulation monitor to process and localize faults.
