1. Overview

2. Key Features

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

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

• Accepts 4–20 mA field transmitters (2‑wire / 4‑wire)

• Channel‑to‑channel & field‑to‑backplane isolation (reinforced)

• Built‑in surge suppression (TVS diodes) and EMI/RFI filtering

• Per‑channel fault detection: open circuit, short circuit, overvoltage, ground fault

• Dual redundancy: single channel/module fault does not affect safety function

• Screw terminals for easy field wiring (16 AWG max)

• Conformal coated PCB for harsh industrial environments

• Hot‑swap compatible (online replacement without system shutdown)

• LED status indicators per channel (front‑panel visible)
