ABB Industrial Control and I/O Termination

The TU818 provides a compact physical termination interface for field signal wiring. Its terminal arrangement supports either one 32-signal configuration or two 16-signal configurations.

Because the supplied documentation identifies the unit as a Module Termination Unit, the TU818 should not be treated as an active I/O processor or communication interface. Instead, it provides the termination hardware required for the connected signal circuits.

The 50 V specification defines the stated voltage class for the termination unit. Therefore, connected field circuits must remain within the applicable electrical limits of the complete I/O assembly and associated wiring.

Frequently Asked Questions

Q: Does the TU818 process or convert field signals?
A: No. The supplied specification identifies the TU818 as a Module Termination Unit. It provides signal termination rather than signal processing.

Q: How many signal terminals does the TU818 support?
A: The unit supports 1x32 signal terminals or 2x16 signal terminals, according to the ABB catalog description.

Q: Is the TU818 a powered electronic I/O module?
A: The supplied data does not identify an internal power consumption value. The TU818 is specified as a Module Termination Unit rather than an active signal-processing module.

Field Installation Guidelines

1. Mount the TU818 according to the mechanical arrangement of the associated ABB I/O assembly.
2. Verify the terminal configuration before connecting field wiring, using the required 1x32 or 2x16 arrangement.
3. Confirm that connected circuits comply with the stated 50 V voltage specification.
4. Route signal wiring separately from high-current or high-voltage conductors where the installation design requires noise reduction.
5. Maintain correct terminal identification throughout installation and commissioning.
6. Apply the plant grounding and shield termination practices specified for the complete control-system installation.
7. Inspect terminal connections for secure mechanical engagement before energizing the associated circuits.
