ModuleBus Distribution and I/O Density

The TU810 terminates field wiring and distributes the ModuleBus to the installed I/O module. It also passes the ModuleBus onward to the next MTU in the rack. The unit generates the required module position address by shifting the outgoing position signals.

The 16-channel termination arrangement provides a defined physical connection point for compatible S800 I/O modules. Mechanical keying uses two keys with six selectable positions each, providing 36 possible combinations to restrict insertion to the configured module type.

The TU810 functions as a passive termination unit; therefore, the supplied technical data does not specify a separate power-consumption value for the MTU itself. Module power requirements depend on the installed S800 I/O module and system configuration.

Frequently Asked Questions (FAQ)

Q: Does the TU810 provide active I/O signal processing?
A: No. The TU810 is a passive Module Termination Unit. It provides field-signal termination, ModuleBus distribution, position-signal handling and mechanical keying for the associated S800 I/O module.

Q: What is the maximum voltage and current specified for the TU810?
A: The specified maximum voltage is 50 V. The maximum current per I/O channel is 2 A, while the maximum process connection current is 5 A.

Q: Does the supplied data specify hot-swap or firmware compatibility for the TU810?
A: No. The supplied information does not define a hot-swap procedure, firmware version compatibility, or hot-swap electrical limitations. These functions should be evaluated from the documentation for the installed S800 I/O module and system configuration.

Field Installation Guidelines

• Mount the TU810 on the specified DIN rail and engage the integrated grounding latch correctly.
• Confirm that the mechanical key positions correspond to the intended S800 I/O module before insertion.
• Terminate field conductors according to the permitted conductor cross-sections and the applicable S800 installation documentation.
• Keep signal wiring separated from high-current and high-noise conductors where the installation requires electromagnetic interference control.
• Route shields and protective conductors according to the plant grounding and EMC design. Do not use signal shields as substitutes for protective earth conductors.
• Verify the field wiring against the assigned I/O channel before energizing the circuit.
• Confirm that the connected field voltage does not exceed the specified 50 V maximum.
• Inspect the ModuleBus and position-signal connections before installing the associated I/O module.
• Do not infer hot-swap capability from the MTU construction alone; follow the applicable S800 system procedure.
• Maintain the IP20 protection characteristics by installing the unit within an appropriate protected control-panel environment.
