  • Mounting bracket for a programmable logic controller control module
    Patent number: 5157590
    Abstract: A mounting bracket is used for holding a housing enclosing a control module assembly of the type used in programmable logic controllers. The bracket has a base or back side, a right side wall, a lower segment and an upper segment that cooperate to define a mounting bracket for a single control module. The base has mounting slots for attaching the mounting bracket to a panel. The side wall has clearance holes for attaching the mounting bracket to the side of a PLC rack assembly instead if desired. The lower segment contains a threaded insert that aligns with and accepts a mounting screw on the control module and the upper segment mates with a slotted opening on the control module. The control module is fastened to the mounting bracket by one mounting screw. This provides a quick and efficient method of attaching or removing the control module.
