It cannot be used as a direct hot-swap replacement for the sister board variants SDCS-IOB-21 (which handles 24V DC logic inputs) or SDCS-IOB-23 (which is designed for 230V AC applications). Attempting to cross-wire these variants will permanently damage the on-board optocouplers or cause logic recognition threshold dropouts.\n\u003c\/p\u003e\n\n\u003ch3\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003e\nWhen replacing components in older legacy converter setups, check the flat unscreened or screened flat ribbon cable running from the SDCS-CON-4 controller card to the card interface plug. If the ribbon cable path is run too close to heavy AC busbars, electrical noise can corrupt binary tracking signals. Field failures are minimized by ensuring proper placement away from armature fields.\n\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem;\"\u003e\n  \u003cp style=\"color: #9b2c2c; font-weight: bold; margin: 0;\"\u003e\n    CRITICAL WARNING: LIVE 115V AC LETHAL VOLTAGE HAZARD\n  \u003c\/p\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0.5rem 0 0 0;\"\u003e\n    Isolate, decouple, and lock out all primary power lines and separate 115V AC external control voltage feeds connected to the terminal assembly block.
