The T9881 is a simplex analogue output termination assembly from ICS Triplex, purpose‑built for the AADvance safety controller platform. The T9881 provides secure field wiring connections for up to 8 analogue output channels, interfacing with T9481 or T9482 output modules. The T9881 features 1.5 kV channel isolation, redundant 24 Vdc power inputs, and supports 4–20 mA field loops with 0–750 Ω load capability. With SIL 3 certification and a compact 42 mm DIN‑rail format, the T9881 delivers high‑integrity output termination for safety‑critical industrial applications.
Emergency Shutdown Systems (ESD) – Provides 4–20 mA signals to shutdown valves, pressure relief valves, and safety interlocks in refineries and chemical plants
Fire & Gas (F&G) Systems – Drives alarms, gas detectors, and suppression system actuators in hazardous area installations
Turbine Control – Provides position control signals to I/P converters and hydraulic actuators in turbine control systems
Burner Management Systems (BMS) – Controls fuel valves, air dampers, and pilot igniters in combustion applications
Critical Process Control – Provides analogue setpoints for PID loops, valve positioners, and variable speed drives
8 Simplex Commoned Outputs – Provides 8 non‑isolated analogue output channels with a common return, simplifying field wiring for 4–20 mA loops
SIL 3 Certified – Certified per IEC 61508 for use in safety instrumented systems (SIS) up to SIL 3
High Channel Isolation – ±1.5 kVdc withstand for 1 minute, protecting the controller from field transients
High Resolution Output Control – 15‑bit resolution (0.98 µA) for precise current output
Integrated Current Monitoring – 13‑bit resolution (3.9 µA) for diagnostic feedback
Wide Load Range – Supports 0–750 Ω loads, compatible with most field devices
Compact Form Factor – 42 mm width minimizes control cabinet space
The T9881 functions as the field wiring interface between the AADvance controller‘s analogue output modules (T9481 or T9482) and field actuators. The termination assembly receives the controller‘s digital command values, which are converted by the output module into 4–20 mA current signals. The T9881 routes these current signals to the field via its 8 terminal blocks, while providing the field loop power and return path.
Each channel incorporates a series capacitor for EMI suppression and line filtering. The T9881 also provides dual redundant 24 Vdc field power inputs, ensuring high availability for critical loops. The module‘s isolation barrier (±1.5 kVdc) protects the controller from voltage surges and transients originating in the field cabling. Current monitoring and control resolution are maintained at 13‑bit and 15‑bit respectively, ensuring precise loop control and diagnostic feedback.
Q1: What is the difference between T9881 and T9882?
A1: The T9881 is a simplex termination assembly for 8 analogue output channels, supporting a single output module. The T9882 is a dual termination assembly that supports two output modules for 1oo2 or 2oo2 voting configurations, enabling higher safety integrity levels.
Q2: Which output modules are compatible with T9881?
A2: The T9881 is compatible with the T9481 (3‑channel) and T9482 (8‑channel) analogue output modules.
Q3: What load impedance does the T9881 support?
A3: The T9881 supports load impedances from 0 to 750 Ω, limited by the compliance voltage (3–32 Vdc). The typical load is 250 Ω.
Q4: What is the accuracy of the output current?
A4: The calibrated accuracy at 25°C is ±10 µA. Over temperature, the drift is (0.01% + 0.1 µA) per °C. Long‑term accuracy after 5 years at 40°C is 0.44% + 10 µA.
Q5: Is the T9881 hot‑swappable?
A5: Yes. The T9881 supports online replacement without system shutdown, minimising production interruptions during maintenance.
