Module Termination Unit
Module Termination Units (MTUs) act as I/O module carriers and are available as
Compact, Extended, Intrinsic Safety and Redundant MTUs. A Compact MTU
normally offers termination of one wire per channel for a 16 channel module. With
Compact MTUs power distribution of field circuits must be made with external
terminal blocks and current limiting components if required. Extended MTUs with
group-wise isolated interfaces allow for two or three wire termination of field
circuits and provide group-wise or individually fuses for powering field objects.
Extended MTUs which offer two or three wire terminations allows direct field
object cable termination. The need for external marshalling is therefore drastically
reduced or eliminated when Extended MTUs are used. An Intrinsic Safety MTU
offers termination of field objects located in hazardous areas.
A redundant MTU have two ModuleBuses, two positions for I/O modules and a
common process connection.
