TMR Digital Input Signal Termination
The T8801 routes discrete field signals toward the T8403 input module through dedicated termination circuitry.
Each channel incorporates a 220 ohm current-limiting resistor for field-loop signal conditioning and circuit protection.
Dual 24 VDC feeds use diode commoning, providing redundant power distribution to connected field input circuits.
The assembly supports dry contacts, wet contacts, and non-incendive field switches connected through discrete input loops.
The interface supports triple-redundant signal processing when paired with the specified T8403 TMR digital input card.
Frequently Asked Questions
Q: How many digital input channels does the T8801 provide?

Q: Which Trusted system module connects directly with the T8801?
A: The specified interface module is the T8403 24 VDC TMR Digital Input Card.
Q: What field-loop protection does each input channel provide?
A: Each field loop includes a 220 ohm current-limiting resistor for input circuit protection.
Field Installation Guidelines
Install the T8801 on the specified DIN rail or rack location inside the Trusted cabinet.
Verify cabinet clearances and mechanical retention before terminating field conductors at the assembly.
Route digital input wiring separately from high-voltage power conductors and high-current switching circuits.
Maintain consistent terminal identification between field devices, T8801 channels, and the associated T8403 input module.
Use shielded instrumentation cable where required by the installed system design and electromagnetic environment.
Terminate cable shields according to the project grounding specification, avoiding unintended multiple-point shield connections.
Verify both 24 VDC feeds before energization, including polarity, continuity, and diode-commoned supply arrangement.
Confirm field-loop voltage and signal state before connecting live conductors to the termination assembly.
For hazardous-area circuits, verify the installed wiring method against the applicable non-incendive system requirements.
