An electronics module includes a latch with a first latch portion and a second latch portion. The latch portions move between a latched position and an unlatched position. A spring is located between the first and second latch portions and biases the first and second latch portions in first and second directions. The first latch portion comprises an actuation portion located externally from the housing and that is adapted to be manually engaged and moved linearly in the second direction to move the first latch portion from its latched position toward its unlatched position. The second latch portion includes a resilient tail with a locator tab that seats in either a first receiving location or a second receiving location of the first latch portion and that is selectively deflectable to disengage the locator tab from the second receiving location so that the spring moves the latch to the latched configuration.

A housing slice for forming a modular housing for mounting an electrical component on a grounding rail carries a grounding member for grounding the electrical component to the grounding rail. The grounding member extends outside of the housing slice but does not extend beyond the sides of the housing slice to permit side-by-side stacking of the housing slice carrying the grounding member with other housing slices with or without grounding members.

An assembly for attaching and detaching an electronics module from a base includes a feedback assembly that provides an operator with tactile feedback on the relative positioning of the module with the base during attachment or detachment of the module to or from the base. The feedback assembly includes cams on the electronics module and a follower attached to an end of a spring arm on the base. The spring arm forms a portion of a wall that guides movement of the module along the base during attachment or detachment of the module.

A housing slice for forming a modular housing for mounting an electrical component on a grounding rail carries a grounding member for grounding the electrical component to the grounding rail. The grounding member extends outside of the housing slice but does not extend beyond the sides of the housing slice to permit side-by-side stacking of the housing slice carrying the grounding member with other housing slices with or without grounding members.

There is described a peripheral post of railway field devices, comprising: a plurality of control modules operatively connected or connectable by electric cables to respective railway field devices; a rack housing said plurality of control modules, wherein said rack comprises: a wiring frame adapted to be permanently attached to a support surface or to an installation wall, comprising a front side and an opposite rear side and comprising on the rear side first connectors adapted to be electrically connected to end portions of said cables; a support and containment frame of the modules adapted to house said modules and adapted to be coupled to the wiring frame by drawing said support and containment frame near the wiring frame from said front side so as to reach a coupling position.

An electronic device includes a first circuit board and a second circuit board arranged to have their first main surfaces facing each other, and a casing containing the first and second circuit boards. The first circuit board has the first main surface having a first electronic component with a mounting height from the first main surface toward the second circuit board greater than a distance between the first and second circuit boards. The second circuit board has an opening or a cutout as a first hollow portion facing the first electronic component. The first hollow portion receives a part of the first electronic component.

An adaptive mounting rail includes a base element with a first side and a second side, a plurality of rails disposed on the first side of the base element for mounting an electronic device, and a first adaptive mounting element disposed on the second side of the base element allowing to removably mount the mounting rail to a support mounting rail. Further, mounting assemblies including the adaptive mounting rail are described.

A control system includes a module assembly with a base. The base can be configured for engagement with at least one module having electronic circuitry disposed therein or other electronic device. The base includes at least one latching assembly with a lever operable to move a shuttle coupled to the lever to releasably engage the base with an elongated mounting rail.

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.

A control system for mounting to a rail. The control system includes a control assembly and one or more I/O assemblies. The control assembly and each I/O assembly includes a module removably mounted to a base. The base has a body with a channel formed therein that is adapted to receive the rail. A latching assembly is mounted to the body and includes a lever movable between a latched position and an unlatched position, wherein the movement of the lever between the unlatched and latched positions moves latching members into and out of the channel, whereby when the rail is disposed in the channel and the lever is moved to the latched position, the latching members move into the channel, thereby trapping the rail in the channel and securing the base to the rail. When the module is mounted to the base, the module covers the lever of the latching assembly so as to be inaccessible.
