Description
The TU818 is a 32 channel 50 V compact module termination unit (MTU) for the S800 I/O. The MTU is a passive unit used for connection of the field wiring to the I/O modules. It also contains a part of the ModuleBus.
The MTU distributes the ModuleBus to the I/O module and to the next MTU. It also generates the correct address to the I/O module by shifting the outgoing position signals to the next MTU.
Two mechanical keys are used to configure the MTU for different types of I/O modules. This is only a mechanical configuration and it does not affect the functionality of the MTU or the I/O module. Each key has six positions, which gives a total number of 36 different configurations.

The TU818 is designed as a passive interface module, meaning it does not perform signal processing itself. Instead, it provides a structured connection layer between field devices and ABB S800 I/O modules such as AI, DI, and DO series modules. Communication with I/O modules is handled through the internal ModuleBus system, ensuring consistent signal routing within the rack architecture.
Mechanical keying features are built into the unit to prevent incorrect module installation, ensuring compatibility between MTU and corresponding I/O modules. The DIN rail mounting system allows flexible installation inside control cabinets, with support for both horizontal and vertical orientations depending on environmental conditions.
- Oil/Gas: Used on offshore platforms, FSUs, gas plants, and refineries; compact design saves control room space
- Power/Utilities: Integrated into thermal, renewable, and large-scale water treatment facilities
- Chemical/Petrochemical: Deployed in automated plants requiring high availability and extensive routing
- Pharmaceuticals: Ideal for batch processing with strict uptime and quality tracking requirements
- Mining/Metals: Utilized in smelters, cement plants, and crushers with robust grounding and durability
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
DIN Rail Mounting: Mount the TU818 onto a standard DIN rail. Ensure the latching device snaps securely in place, which also establishes the chassis/ground connection.
Mechanical Keying: The TU818 features two mechanical keys to configure it for specific I/O module types.
Each key has 6 positions, yielding 36 different configurations. Adjust these using a screwdriver to align with your corresponding I/O module (e.g., DI818) and prevent improper module insertion.
