Features:
- ABB article HESH447449R11 identifies 70LR01A as a protection relay module.
- System role: implements the documented protection relay function.
- Compatibility requires the documented suffix, hardware execution, connectors, position and project configuration.
HESH447449R11 70LR01A must remain matched to ABB PROCONTROL P13 systems. Isolate the P13 rack circuits, record code-switch and wiring settings, and preserve the documented local-bus address. Verify supply, local-bus communication, diagnostics and every affected process function before return to service.
Official source boundary: manufacturer documentation selected for 70LR01A. Unverified nearby-model values are withheld.
