ABB NTDI21-A Controller Module with 24 V DC Input Voltage 32-Point Marshalling

[✚] 32-Point Marshalling: This isn't just a connector; it's the primary interface for 32 discrete channels. It bridges the gap between raw field wiring and the Harmony/Symphony Plus I/O bus. Essential for high-density cabinets where rail space is a nightmare.
[✚] Galvanic Barrier Logic: Built to handle the "dirty" electrical environments of a plant floor. It provides the necessary surge isolation to ensure a field-side short doesn't fry your expensive HCU (Harmony Control Unit) or controller backplane.
[✚] Passive Reliability: No active CPU here means zero heat-sink requirements. You can stack these in the rack without worrying about thermal de-rating or localized hotspots that usually kill active modules.
[✚] Legacy "Drop-In" Capability: Specifically engineered for Infi 90 / Harmony life-extension. It’s a 1:1 "form-fit-function" swap for older NTDI units, meaning zero re-drilling or re-wiring during an MRO (Maintenance, Repair, and Overhaul) window.
