Overview
The AIL200-12 insulation fault locator, together with the AIM-T500L insulation monitor and ASG200 test signal generator, forms a complete insulation fault location system. It is designed for industrial unearthed AC systems (IT systems) in environments such as mines, glassworks, electric furnaces, metallurgical plants, chemical plants, explosion-hazard areas, computer centres, and emergency power supplies. The device monitors insulation faults and precisely locates the faulty branch.

Function
| Multi-circuit Fault Location | Supports up to 12 independent branches with AKH-0.66L series residual current transformers. Unused circuits can be disabled via the LED panel. |
| CAN Communication Interface | Built-in CAN interface (H, L) for real-time data exchange with AIM-T500L and ASG200, ensuring coordinated fault location. Long-distance communication supported with shielded twisted pair and optional 120Ω termination resistor. |
| Relay Alarm Output | Provides a relay output (D01+, D01-) for alarm signaling when an insulation fault is detected. |
| Self-test Function | Press the self-test button to verify device status – all LEDs light up and relay closes for 2 seconds, then result is displayed. |
| Easy Installation | Compact design, terminals for up to 12 CTs (no polarity), and simple wiring. |
