Features:
- Triple Modular Redundancy (TMR) Architecture for SIL 3 Applications
- Fully Isolated 16-Channel Digital Input Termination
- Hazardous Area & Environmental Compliance
The T9803 supports 2oo3D (two-out-of-three with diagnostics) voting logic, enabling the system to tolerate a single module failure and continue safe operation. This architecture ensures both high safety integrity and high availability for critical emergency shutdown and fire & gas systems.
Designed for reliable field signal acquisition, the T9803 provides channel-to-channel and channel-to-chassis isolation (withstanding ±1.5 kVdc for 1 minute). This eliminates cross-talk, ground loops, and protects against EMI/RFI interference in electrically noisy environments such as variable frequency drive (VFD) cabinets and high-voltage switchyards.
Certified for use in Class I, Division 2, Groups A, B, C, and D (North America) and ATEX/IECEx Zone 2 (Ex ec IIC T4 Gc), the T9803 operates reliably from -25°C to +60°C. When installed in a certified IP54 enclosure with vertical orientation and 85°C rated conductors, it meets rigorous safety and environmental standards for oil & gas and chemical facilities.
The T9803 ICS Triplex digital input termination assembly may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Ambient Temperature Range – -25°C to +60°C, supporting outdoor and unconditioned shelter installations.
- Pollution Degree 2 (IEC 60664-1) – Designed for non-conductive pollution environments with occasional temporary condensation.
- Humidity & Coating Protection – Conformal coating meets US MIL-146058C and IPC-CC-830, approved for defense and aerospace-level moisture/humidity resistance.
- Installation Orientation – Vertical mounting only, requiring no forced air cooling, but must be placed in a tool-accessible IP54 minimum enclosure for hazardous locations.
- AADvance Controller Ecosystem – Directly compatible with T9300 I/O Backplane and T9110 Processor Module for SIL 2 and SIL 3 configurations.
- Redundancy Configurations – Works in simplex, dual (1oo2D), and TMR (2oo3D) architectures without special cables or interface units.
- Backward Compatibility with Termination Assemblies – Shares physical and electrical compatibility with T9801 (simplex) and T9802 (dual), allowing modular safety upgrades.
- Global Safety Certifications – UL listed for hazardous locations (File E251761), ATEX DEMKO 11 ATEX 1129711X, and IECEx UL 12.0032X, ensuring global plant acceptance.
- Emergency Shutdown Systems (ESD) – Provides high-integrity digital input processing for emergency trips.
- Fire & Gas (F&G) Protection Systems – Interfaces with flame, gas, and smoke detectors in SIL 3-rated loops.
- Burner Management Systems (BMS) – Monitors flame safety switches and valve position feedback.
- High-Availability Process Control – Suitable for critical rotating machinery protection where spurious trips must be minimized.
