Features:
- Failed Switch diagnostics compare commanded output state with internal switch response.
- Selectable 10 to 100 ms input filtering adapts response to field-signal conditions.
- Per-circuit fault reporting can be enabled for host-controller diagnostics.
For
IC660BBS102, a commanded ON or OFF transition is checked against the internal switch indication so a mismatch can be reported to the controller as a Failed Switch condition.
Input filtering is selected in 10 ms increments, allowing the configured response time to reject brief field disturbances without changing the electrical input threshold.
The Report Faults setting is assigned by circuit, so diagnostic messages can be passed to the CPU for the points that require supervised operation.
After manufacturer End-of-Life (EOL), the General Electric IC660BBS102 Isolated I/O Block may remain available through Apter Power for purchase and official-document support.

Stored Point Behavior
- Pulse testing: The block can apply the documented output pulse test for circuit verification.
- Power-up state: Configurable startup defaults determine point behavior when the block is initialized.
- Hold operation: Selected outputs can retain their last commanded state under the supported communication-loss setting.
- Feedback mode: A circuit assigned as output with feedback returns its actual switching indication with the commanded data.
Protected Output Recovery
- Short-circuit action: Electronic protection shuts down the affected output when a short is detected.
- Restart command: After the field fault is cleared, the point can be restarted from the Hand-Held Monitor or host CPU.
- Point isolation: A protected output fault is handled at the affected circuit instead of requiring a replaceable fuse for the entire block.
- Status reporting: Overload and shutdown information is returned through Genius diagnostics for controller-level fault handling.
Bus and Configuration Controls
- Baud-rate changes: An IC660HHM501 is required when the block bus rate must be changed.
- Redundancy setup: CPU-redundancy parameters are configured with the supported HHM501 functions.
- Host interfaces: The block exchanges I/O data through compatible Genius bus controllers, PCIMs, or QBIMs.
- BSM control: Bus Switching Module control can be enabled for the documented Genius redundancy arrangement.
