ABB TU818V1 Compact Module Termination Unit, MTU, 50V 3BSE069209R1
S800 I/O NEW
Description of TU818V1
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.
Features and benefits - Compact installation of I/O modules using one-wire or two-wire
(depends on I/O module type) connections.
- Up to 32 channels of field signals and process power connections.
- Connections to ModuleBus and I/O modules.
- Mechanical keying prevents insertion of the wrong I/O module.
- Latching device to DIN rail for grounding.
- DIN rail mounting.
