Building on the H1A, the IS210SCLSH2A doubles the logic capacity and adds cross-channel diagnostics for high-availability applications. Each channel pair can be operated in 1oo2 (one-out-of-two) redundant mode, ensuring that a single board fault does not compromise critical signaling. All logic routines are implemented in flash-based CPLDs, allowing field updates without hardware replacement.
Installation
Mount this board in a dual-slot enclosure marked “SCLS-2A.” Secure the locking handles, then attach field wires to both channel A and B terminals. Ensure that both channels share the same ground reference and ribbon-cable connector. Power up the rack—both channel-status LEDs should glow solid green.
Operation
In redundant mode, both channels execute the same logic in parallel. The on-board monitor compares results; if a discrepancy is detected, the module alarms and places the system into a safe state. Updates to Boolean logic tables can be downloaded over Ethernet or via a handheld GE service tool, minimizing downtime.
