## Abstract

This disclosure provides a field termination assembly (FTA) providing for ease of mounting to a support rail. The FTA is easily mounted to a base which is secured to a support rail. The housing includes one or more slots each configured to receive a respective adaptor module configured to be inserted into the slot. Each adaptor module may be configured to perform at least one function related to an associated input or output signal.

## Claims

### Claim 1

An apparatus comprising a field termination assembly (FTA), the apparatus comprising:
a housing including one or more slots, each slot of the one or more slots configured to receive an adaptor module for one or more input/output (I/O) channels associated with an industrial process control and automation system, said adaptor module configured to perform at least one I/O function in the industrial process control and automation system; and
a base coupled to said housing, said base configured to be secured to a support rail, said base includes an opening through which a pin extends to engage a plate to cooperatively grip a flange on the support rail,
wherein said housing being configured to be mounted to said base.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein said housing is configured to be mounted to said base after said base is secured to said support rail.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein said base includes a loop and said housing includes a catch that engages said loop to hingeably couple said base to said housing.

### Claim 4 (depends on 3)

The apparatus of claim 3, wherein said housing includes a hitch and said base includes a latch that engages said hitch to mount said base to said housing.

### Claim 5 (depends on 4)

The apparatus of claim 4, wherein said catch engages said loop in a first coupled position and said housing and said base pivot with respect to each other into a second mounted position.

### Claim 6 (depends on 4)

The apparatus of claim 4, wherein said latch includes a beveled distal edge to facilitate engagement with said hitch.

### Claim 7 (depends on 4)

The apparatus of claim 4, wherein said latch includes a recess track along which said hitch rides into an opening to engage said latch.

### Claim 8 (depends on 1)

The apparatus of claim 1, wherein said base includes a recess for receiving said support rail, a groove on a first side of said recess accepts said flange, comprising a first flange, and a channel on a second side of said recess for receiving a second flange of said support rail.

### Claim 9 (depends on 8)

The apparatus of claim 8, wherein said channel receives said second flange in a first received position and said base and said support rail pivot with respect to each other such that said groove receives said first flange of said support rail in a secured position in which said pin can engage said plate to secure said base to said support rail.

### Claim 10 (depends on 9)

The apparatus of claim 9 in which said groove defines an acute angle with a plane defined by said recess.

### Claim 11 (depends on 1)

The apparatus of claim 1 wherein said support rail is located in a cabinet and a plurality of bases are secured to said support rail and said housing is one of a plurality of housings and respective ones of said plurality of housings are mounted on respective ones of said plurality of bases.
