Compact MTUs are 58 mm (2.3”) wide and extended MTUs are 120 mm (4.72”) wide. The two
MTU types can be mixed and matched within an I/O-station to fit a user’s needs. Choice of
compact MTU or extended MTU can be made freely trading space versus termination needs.
Compact and extended MTUs are available with rated isolation voltages 50 V and 250 V.
The 50 V types can be used with all 24 V or 48 V discrete I/O and analog I/O modules.
The MTUs with 250 V rated isolation voltage are used with all 120 V and 250 V rated I/O
modules. There is also one compact MTU for modules with Intrinsically safe interface.
