Abstract: An electronics module having a latch assembly including first and second reciprocating latch portions adapted to engage respective first and second opposite edges of a mounting rail. Each of the latch portions includes a locking tab, the locking tabs movable away from each other from a latched position to an unlatched position, the first and second latch portions being coupled together for reciprocating motion, at least one of said latch portions including an actuator portion extending from the housing for manual actuation of the latch assembly between the latch and unlatched positions.

Abstract: This disclosure regards a self-keying system for an input/output (I/O) device. An I/O module mountable on a terminal base exchanges I/O signals with external devices via the terminal base. The I/O module comprises a key, and the terminal base comprises a locking assembly to allow insertion of only compatible I/O modules into the terminal base. The locking assembly comprises parallel slots containing a plurality of lock pins movable in the slots between a biased position and a second position. A blocking member is actuated by the key to block each of the lock pins in their respective position to key the base. A maintaining member maintains the blocking member in the keyed position. After keying, a non-compatible key would be rejected from the locking assembly due to the blocked lock pins. A reset to the unkeyed configuration may be accomplished without the use of tools by actuating the maintaining member.

Abstract: A system including a support structure, a plurality of terminal bases mounted to the support structure, a plurality of migration adapters, each migration adapter mounted to a respective terminal base and having first and second adapter connector structures and including first and second backplane connectors for mating with corresponding backplane connectors of one or more adjacent migration adapters mounted to respective adjacent terminal bases for forming a backplane electrically coupling the plurality of migration adapters, and a plurality of I/O modules mounted to the plurality of migration adapters.

Abstract: A method of assembling a connector module is provided. The method of assembling includes abutting an engagement surface of a connector extending from a circuit board with corresponding engagement surfaces of first and second support members disposed within a housing. The method of assembling includes resisting movement of the connector towards a base of the housing at a first end of the connector through a substantially perpendicular extension from at least one of the first and second support members. The method of assembling includes constraining lateral movement of the connector through engaging a receptacle formed on a second end of the connector with a pin of the first support member.

Abstract: An input/output (I/O) device for an automation control system includes a device housing containing control circuitry, the device housing being mountable to a support, a control power input for receiving control power from a first adjacent I/O device when connected thereto, the control power input configured to supply control power to the control circuitry, a control power output for outputting control power to a second associated adjacent I/O device, a field power input for receiving field power from the first associated adjacent I/O device when connected thereto, and a field power output for transmitting field power to the second associated I/O device. The field power input is selectively removable to prevent field power from being received by the I/O device from the first associated adjacent I/O device when connected thereto.
