The T8800C is a 40-channel 24V DC Digital Input Field Termination Assembly (FTA) designed for use in the Trusted System. It provides easy wiring and features enhanced security with Trusted input circuitry. The module includes comprehensive internal diagnostics to detect both covert and overt failures, ensuring rapid fault identification across the system.

The T8800C leverages advanced fault tolerance and fault detection mechanisms, allowing for quick identification of most system element issues. The Expander Processors are naturally redundant, capable of withstanding multiple faults, and support a fixed online repair configuration in adjacent slots, requiring minimal intervention. The module also provides isolation between channels and ground, further enhancing its reliability and security in critical industrial applications.

FAQ
1. What is the role of the T8800C in the Trusted System?
