Features:

  • Provides Flexible And Redundant Field Connections For High-Integrity Systems
  • Supports Dual Digital Input Modules With Clear Wiring And Fuse Organization
  • Ensures Reliable Operation Across Wide Temperature, Humidity, And Shock Conditions
The ICS Triplex T9802 Digital Input Termination Assembly is engineered to link field wiring to digital input modules in Trusted® and AADvance high-integrity systems. Supporting 16 dual-configured channels, it allows flexible allocation of inputs and simplifies integration in redundant or fault-tolerant architectures. Unlike the earlier T9801 simplex termination assembly, the T9802 enables dual module operation, providing higher system reliability and channel redundancy.

Designed for robust industrial use, the T9802 operates over a voltage range of 18–32 Vdc with a maximum current of 6.5 mA per channel. It maintains functionality in challenging environments from –25 °C to +60 °C and can tolerate storage and transport temperatures from –40 °C to +70 °C. Relative humidity tolerance is 10% to 95% RH non-condensing, and the assembly is rated to withstand vibration at 5–9 Hz and shock up to 15 g peak, 11 ms duration. These environmental and mechanical tolerances surpass those of older simplex modules like T9801, ensuring reliable operation in demanding field conditions.

The T9802 features a printed circuit with screw terminal blocks for field wiring, module connectors, and optional fuses with labeled covers for easy identification. Field wiring connectors are arranged for intuitive installation, reducing wiring errors and simplifying maintenance. By supporting dual configurations, the T9802 enhances fault tolerance and provides more flexible system design compared to T9801, making it ideal for SIL 3 or other high-integrity industrial applications.

The T9802 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).

Description
The ICS Triplex T9802 Digital Input Termination Assembly provides reliable field-to-module connections for Trusted® and AADvance high-integrity control systems. Supporting up to 16 channels in a dual configuration, it accommodates both 8- and 16-channel digital input modules. Compared to the older T9801 simplex termination assembly, the T9802 supports dual module configurations, enabling higher redundancy and fault-tolerant system design, which is critical for SIL 3 applications.

Engineered for robust industrial operation, the T9802 operates across a voltage range of 18–32 Vdc with a maximum current of 6.5 mA per channel. It maintains functionality in environmental conditions from –25 °C to +60 °C and can withstand storage and transport temperatures from –40 °C to +70 °C. Relative humidity tolerance ranges from 10% to 95% RH (non-condensing), while mechanical stresses include vibration at 5–9 Hz and shock up to 15 g peak, 11 ms duration (½ sine). These characteristics make it more resilient than earlier models like T9801, which have more limited environmental tolerance.

The termination assembly is designed as a printed circuit with screw terminal blocks for field wiring, connectors for plug-in I/O modules, and optional fuses with clearly labeled covers. The module sockets are positioned for intuitive installation, with field wiring connectors on the left and fuse covers on the right. This design simplifies wiring, reduces installation errors, and allows for easy maintenance. By supporting dual configurations, the T9802 provides improved system reliability over simplex or older assemblies like T9801, especially when integrating redundant or fault-tolerant I/O modules.

Compatible with digital input modules requiring 16 channels, the T9802 supports AADvance and ICS Triplex systems, including configurations where multiple termination assemblies are linked. Its dual configuration allows designers to implement higher integrity systems with flexible channel allocation and simplified fault monitoring. Overall, the T9802 provides a robust, easy-to-install solution that enhances redundancy, environmental tolerance, and operational reliability compared to earlier termination assemblies.

Technical notes
The ICS Triplex T9802 is a passive dual termination assembly with no fuses or onboard overcurrent protection — field power must be externally current-limited for UL/ATEX/IECEx compliance. Its fixed polarization keying (Key A=2, B=1, C=1) enforces exclusive mating with T9401/T9402 digital input modules and cannot be user-modified. The integrated precision resistor network (R1=15KΩ, R2=3K9Ω) enables open-circuit, short-circuit, ON, OFF, and over-voltage detection for line-monitored ESD/F&G inputs. The unit is fully passive — no firmware, no EEPROM, no field updates — and provides no internal signal ground isolation; shields must terminate to an external instrument ground busbar.
