T9832

T9832 is a 16‑channel, dual‑redundant, fully isolated analog input termination assembly for the AADvance T9000 safety system. It provides field wiring interface, signal conditioning, surge protection and galvanic isolation for 4–20 mA transmitters, working with T9432 16‑channel analog input module. T9832 is the dual‑redundant, isolated counterpart to T9831 (simplex) and T9833 (TMR), designed for fault‑tolerant analog signal acquisition in SIL 3 safety loops (ESD, F&G, BMS, critical process control).

1. Overview

T9832 is a 16‑channel, dual‑redundant, fully isolated analog input termination assembly for the AADvance T9000 safety system. It provides field wiring interface, signal conditioning, surge protection and galvanic isolation for 4–20 mA transmitters, working with T9432 16‑channel analog input module.
T9832 is the dual‑redundant, isolated counterpart to T9831 (simplex) and T9833 (TMR), designed for fault‑tolerant analog signal acquisition in SIL 3 safety loops (ESD, F&G, BMS, critical process control).

2. Key Features

  • 16 analog input channels, Dual redundant, fully isolated per channel

  • Dedicated for T9432 (16‑Ch 4–20 mA analog input module)
