T9802

The T9802 is a 16‑channel dual‑isolated digital input termination assembly (TA) for the AADvance T9000 safety system. It provides the field wiring interface for T9401 / T9402 digital input modules, supporting 24 VDC discrete signals from emergency stop buttons, pressure switches, limit switches, and safety‑related devices in ESD, F&G, and BMS applications. It features per‑channel electrical isolation, dual‑path redundancy, hot‑swappable fuses, and comprehensive fault diagnostics for high‑availability safety systems.
