Features:

  • High-Precision 15-Bit Output Control with 200 µA Safety Accuracy
  • Dual-Mode Fault-Tolerant Operation (1oo2D)
  • Configurable Fail-Safe Behavior with Comprehensive Line Monitoring
The T9482 delivers output current with 0.98 µA control resolution (15-bit) and monitoring resolution of 3.9 µA (13-bit). Safety accuracy is maintained at 200 µA, ensuring reliable operation within SIL 3 safety loops without dangerous undetected drift.

When configured in dual mode, two T9482 modules communicate via an inter-module link to provide fault-tolerant operation (1oo2D). Each channel automatically splits the output current (half per module), and a single module failure does not interrupt the loop—maintaining output availability while the faulty unit is replaced.

Each channel supports user-programmable failure modes: hold last state, fail-safe to a predefined value (e.g., <2 mA), or user-specified output state. Integrated short-circuit and open-circuit line monitoring, reverse current protection, and per-channel voltage/current monitoring enable rapid fault diagnosis without field device disconnection.

The T9482 ICS Triplex Analogue Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The T9482 is a high-integrity analog output module engineered by ICS Triplex (a Rockwell Automation brand), designed to deliver precise, fault-tolerant 4–20 mA current signals for safety instrumented systems (SIS) and process automation networks. As a flagship component of the AADvance distributed control system (DCS) architecture, this module serves as a critical interface between control systems and field devices — including actuators, valves, and variable frequency drives — across industries where operational reliability, regulatory compliance, and fault tolerance are non-negotiable. 

Targeting oil & gas, power generation, petrochemical processing, and nuclear energy sectors, the T9482 combines 8 isolated channels, dual-module redundancy, SIL 3 certification, and rugged environmental resilience to ensure uninterrupted operation in harsh industrial environments where system failure could lead to catastrophic safety risks, financial losses, or environmental harm.

At its core, the T9482 is optimized for safety-critical signal distribution, featuring 8 fully isolated current-sink output channels with 1500 VDC channel-to-channel isolation — eliminating cross-talk and protecting against electromagnetic interference (EMI), radio frequency interference (RFI), and ground loops common in industrial settings.

Each channel delivers a configurable 4–20 mA current loop (the industry-standard analog signal for process control) with exceptional precision: 15-bit control resolution (0.98 µA least significant bit), 13-bit monitoring resolution (3.9 µA), and ±0.5% full-scale accuracy ensure consistent, reliable control of critical process variables such as flow, pressure, temperature, and level.
