The 5094-MB base is an Allen-Bradley manufactured mounting base. It is a FLEX 5000-compatible base. It takes in 100 milliamps of backplane current and runs with a a voltage rating of 15 Volts DC. The terminal base consists of a mounting base and a removable terminal block. It can be easily mounted by using a DIN rail that is made of zinc plate and chromate steel. It has a small form factor and dimensions of 3.35 inches in height, 3.70 inches in width, and 1.48 inches in depth. It weighs around 0.16 pounds. The 5094-MB mounting base has an open enclosure and it meets the T4 North American Temperature code. The terminal base assemblies are made to be used in an environment with a temperature not exceeding 70 degrees Celsius.

The 5094-MB mounting base is able to withstand vibrations of up to 5 G between 10 and 500 Hertz and shocks of 30 G when operating and when not operating. The mounting base has been certified with the c-UL-us, CE, and RCM standards. The 5094-MB base is used with the FLEX 5000 I/O modules that are used with the Logix 5000 controllers. The mounting base can accommodate different components of the I/O modules. During the installation of different components of the I/O, enough space should be left free for airflow. The module temperature is maintained by using the natural convection cooling method. The 5094-MB base should be placed on a firm and stable surface during the mounting or installation process. All the power sources should be disconnected during installation.
