Abstract: Present embodiments include an automation control system that includes an input/output device module with a device bus therein. The input/output module also includes a first bus contact on a first side of the input/output device module and communicatively coupled with a first end of the device bus, and a second bus contact on a second side of the input/output device module and communicatively coupled with a second end of the device bus. The second side generally faces an opposite direction from the first side and the input/output device module is configured to be coupled with additional input/output device modules positioned on the first and second sides of the input/output device module via the first and second bus contacts.

Abstract: An electronics module includes a base and a cover connected to the base. The base includes a recess adapted to receive an associated mounting rail. At least one fixed rail constraining tab is located adjacent a first edge of the recess and is adapted to engage a first flange of the associated mounting rail. First and/or second latch arms are located adjacent a second edge of the recess that is opposite the first edge of the recess. The first and second latch arms are connected to a fixed portion of the second edge and project outwardly relative to opposite lateral sides of the fixed portion. Each of the first and second latch arms includes a rail capture tab.

Abstract: A serial optical data transmission system is provided. The serial optical data transmission system includes a displaceable optical pathway disposed adjacent to a slot configured to receive a first monitoring and/or control module. The optical pathway is biased towards a serial optical data bus position for transmission of optical data to or from at least one second monitoring and/or control module when the first monitoring and/or control module is removed from the slot. Further, the optical pathway is displaced from the serial optical data bus position when the first monitoring and/or control module is in the slot.

Abstract: An electronics module includes a base including a recess adapted to receive an associated mounting rail such as a DIN rail. At least one rail constraining tab is located adjacent a first side of the recess and is adapted to capture a first flange of the associated mounting rail in the recess. First and second flexible resilient latch arms are located adjacent a second side of the recess. The first and second flexible latch arms include respective first and second locking tabs connected thereto, wherein the first and second locking tabs project into the recess and are located to capture a second flange of the associated mounting rail in the recess when the first and second latch arms are in respective latched positions, and wherein the first and second locking tabs are withdrawn from the recess when the first and second latch arms are in respective unlatched positions.
