ABB S800 I/O Termination Characteristics

The TU811V1 functions as a physical Module Termination Unit rather than an active communication module. Therefore, it does not perform independent signal processing or network communication.

The unit provides termination for eight field signal connections and interfaces the field wiring with the associated I/O assembly. Furthermore, its 250 V designation defines the cataloged voltage class for the termination unit.

ABB industrial control systems can use backplane communication between active I/O modules and the controller. However, the supplied TU811V1 data does not specify a communication velocity, firmware version, or independent network interface. Those parameters should therefore be taken from the compatible I/O module documentation.

Frequently Asked Questions

Q: How many signal terminals does the TU811V1 provide?
A: The TU811V1 provides 1 x 8 signal terminals.

Q: Does the TU811V1 require an independent power supply?
A: The supplied data identifies the unit as a Module Termination Unit and does not specify an independent power-consumption value. Do not assign a separate supply requirement without the applicable system documentation.

Q: What are the physical dimensions of the TU811V1?
A: The unit measures 170 mm in height, 58.5 mm in width, and 64 mm in depth.

Field Installation Guidelines

• Install the TU811V1 according to the mechanical arrangement specified for the compatible ABB I/O assembly.
• Verify the module identification and product ID before wiring: TU811V1, 3BSE013231R1.
• Confirm field-circuit voltage compatibility with the 250 V catalog rating before energization.
• Route signal wiring separately from high-current power conductors where the installation design permits.
• Maintain proper conductor identification and terminal labeling throughout the field wiring.
• Apply the applicable site grounding and shield termination practice for the connected signal circuits.
• Inspect terminal connections for secure mechanical engagement before applying field power.
• Do not apply unsupported supply voltages or assume hot-swap capability without confirmation from the associated ABB system documentation.
