Features:
- Defined RE.316 role: Binary I/O Unit is a distinct relay hardware object
- Paired ABB identity: HESG material and 316DB63 code control the spare
- Protection-system boundary: relay restoration requires role-specific testing
The 316DB63 role separates this unit from the other boards in an RE.316 chassis.
The complete HESG code provides material-level control for procurement and receiving.
Discontinued supply status makes the binary channel assignment and trip or signal circuit mapping decisive before the relay is returned to service.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Unit function: ABB defines 316DB63 as the binary i/o unit.
- System context: the unit belongs to the RE.316 hardware architecture.
- Object boundary: it is distinct from the platform's other processor, I/O, power and transformer units.
- Service effect: replacement scope can be limited to the failed hardware role.
- Material identity: HESG324321R3 controls the exact ABB unit.
- Unit code: 316DB63 must remain on the service record.
- Primary dependency: binary channel assignment and trip or signal circuit mapping governs release.
- Stop condition: a role match without the complete identity is insufficient.
- As-found record: preserve chassis position and connected circuits before removal.
- Protection scope: test only after the unit-specific configuration is restored.
- Legacy status: repaired or stocked units need traceable identity and condition.
- Handover: retain the completed relay test record with the replacement history.
- Installed relay service: RE.316 binary signal interface service.
- Outage restoration: Protection-trip I/O maintenance.
- Repair support: Legacy relay input/output repair.
