ABB 3BSE013231R1 S800 I/O TU811V1 Compact Module Termination Unit

  • The TU811V1 is an 8-channel, 250 V compact module termination unit (MTU) designed specifically for the S800 I/O system. At its core, this is a passive unit—no need for external power to run it—with two key jobs: acting as the reliable link between field wiring and your I/O modules, and housing a segment of the ModuleBus that keeps the whole system communicating smoothly.
  • Beyond just connecting wires, the TU811V1 plays a critical role in ModuleBus distribution. It routes the bus signal not only to the attached I/O module but also on to the next MTU in the chain, ensuring seamless data flow across your entire I/O setup. It also handles address assignment for the I/O module automatically: by shifting the outgoing position signals to the following MTU, it generates the correct, unique address for each module—no manual programming needed here.
  • What makes it flexible for different setups are the two mechanical keys built into the unit. These keys are used to configure the MTU for compatibility with various I/O module types, but it’s important to note that this is purely a mechanical adjustment—it doesn’t impact the functionality of either the MTU itself or the connected I/O module. Each key has six adjustable positions, which adds up to 36 distinct configuration combinations total. That kind of versatility means you can use the same TU811V1 unit across a range of I/O setups without swapping out hardware.
