ICS Triplex T9801 – 16-Channel Digital Input Termination Assembly
Product Overview
The ICS Triplex T9801 is a digital input termination assembly designed for simplex configurations within the ICS Triplex AADvance control platform. It provides termination for 16 non-isolated digital input channels and interfaces with compatible T9401 or T9402 digital input modules.
The assembly is used to connect field digital signals to the control system while maintaining the intended wiring and termination arrangement. This makes it relevant to discrete-status monitoring in safety and critical-control applications, including process control, emergency shutdown, fire and gas, and rotating machinery systems. Available technical listings identify the unit as a simplex, commoned digital input termination assembly.

ICS Triplex T9801
Key Features and Benefits — T9801
- 16 non-isolated digital input channels for simplex applications.
- Provides the field termination interface for compatible digital input modules.
- Designed for integration with the ICS Triplex AADvance architecture.
- Commoned input arrangement simplifies connection of suitable field signals.
- Appropriate for maintenance, replacement, and system restoration where the original termination configuration must be retained.
- The termination assembly itself should not be confused with the digital input module; channel electronics and field termination perform different functions.
The exact physical dimensions and weight vary across reseller listings, so procurement teams should verify the actual assembly drawing or installed unit before transport planning.

Installation and Maintenance — T9801
Before replacement, isolate the relevant control-system power and follow the site’s lockout/tagout procedure. Record field wiring, terminal identification, module position, and jumper or configuration details before removal.
Inspect terminal connections for looseness, corrosion, damaged insulation, or signs of overheating. Because this is a termination assembly, wiring accuracy is critical; a wrong field connection can create misleading digital states even when the associated I/O module is operating normally.
Personally, I would verify the part number from the nameplate and cross-check the termination drawing rather than relying only on physical appearance.
Product Warranty — T9801
Warranty conditions depend on the supplier and item condition. For critical automation spares, procurement records should include the exact part number, condition, country of origin, inspection information, and any available test documentation. The ICS Triplex T9801 should be replaced only with a unit confirmed to match the required simplex termination configuration.
