BASIC INFO
ABB TU838 Extended Module Termination Unit, MTU 50V 3BSE008572R1 I-O_Module Extended Terminal block
The TU838 MTU can have up to 16 I/O channels. The maximum rated voltage is 50 V and maximum rated current is 3 A per channel.
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.
The MTU can be mounted on a standard DIN rail. It has a mechanical latch that locks the MTU to the DIN rail.
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
Complete installation of I/O modules using 3-wire connections, fuses and field power distribution.
Up to 16 channels of field signals and 8 process power connections.
Two channels share one fused transducer power terminal.
Process voltage can be connected to 2 individually isolated groups, if the I/O module supports it.
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.
