Features:
- Eight AC/DC circuits are arranged as four isolated pairs
- Each circuit can be used as an input or electronically fused output
- Failed Switch diagnostics compare commanded and actual output behavior
IC660BBS100 denotes the isolated eight-circuit version with Failed Switch diagnostic capability; its circuits are paired for electrical isolation.
The block observes field voltage as well as commanded output state, enabling additional diagnostic reporting while it exchanges I/O data over the Genius bus.
For an obsolete-unit replacement, compare the complete electronics and terminal assembly markings and confirm whether external manual switches could affect failed-switch detection.
The General Electric IC660BBS100 115 VAC/125 VDC 8-Circuit Isolated I/O Block with Failed Switch Diagnostic is documented as discontinued by the OEM; quotation, documentation, and legacy-system support remain available from Apter Power.

Four circuit pairs
- Pair structure: The eight I/O points are separated into four isolated pairs.
- Source selection: Each pair may use a compatible AC or DC field source.
- Input/output mix: Configure circuit direction according to the application.
- Separation: Maintain the documented isolation in terminal and enclosure wiring.
Electronic output control
- Short response: An electronically fused output shuts down after a fault.
- Reset method: Re-enable the circuit only after the cause has been removed.
- Thermal supervision: Investigate loading and enclosure temperature after an alarm.
- Output rating: Keep each load and the full block inside the manual limits.
Failed-switch behavior
- State comparison: Failed Switch detection compares commanded and observed output conditions.
- Parallel switches: External contacts can create a discrepancy that must be evaluated.
- Open wire: Use tristate-input diagnostics only with suitable field circuits.
- OEM transition: Review IC660BBS102 as the documented successor to the obsolete block.
