4. Main Functions

1. 16‑channel isolated 4‑20 mA analogue signal acquisition: Interface for pressure, level, flow, gas‑detector transmitters in safety‑critical loops; supports HART‑5 to read additional device diagnostic dataRockwell A…。
2. Per‑channel LED indication for channel status and fault diagnosis for fast on‑site troubleshooting.
3. Comprehensive loop diagnostics: detect open‑loop, under‑range, over‑range fault conditions; fault events time‑stamped for SOE.
4. Hot‑swap capability: replace module online without shutting‑down safety logic.
5. Flexible I/O redundancy configuration: simplex / dual / TMR voting I/O groups configured via AADvance Workbench software.
6. Only interoperable with AADvance platform (T9110/T9110C processor), cannot work with Trusted T8000 T84xx / T88xx hardware.

5. Typical Applications

1. On‑shore / offshore SIS‑ESD emergency shutdown system for process analogue variable acquisition.
2. Fire & Gas safety system for multi‑point gas‑detector 4‑20 mA signal input.
3. Petrochemical, power‑plant safety‑critical pressure, level, flow monitoring loops.

6. Important Notes

1. T9432 belongs to AADvance platform, not Trusted T8000. Incompatible with T8000 series cards and T88xx FTA terminals. Must pair with AADvance dedicated analogue FTA.
2. Two variants available: T9432(standard), T9432C(conformal coated offshore version). Firmware cannot be cross‑loaded.
3. Support simplex, dual redundant or TMR voting I/O groups configured via AADvance Workbench software.
4. Hot‑swap operation permitted; install only inside certified safety cabinet, not for direct hazardous‑zone mounting.
5. HART data is secondary diagnostic information, safety logic shall use 4‑20 mA analogue value.
