7.3.4.4 Equipment Description, Receiver Line-to-Rail Coupler 7A377-2-f
The 7A377-2-f coupler assembly consists of a tubular PVC plastic enclosure with mounting
plates extending across the base suitable for shelf mounting. It is similar to the 7A377-1-f, but
rather than having four wires protrude from the top of the assembly, the top of the 7A377-2-f has
four AREMA binding posts that provide terminal connections for interface wiring (see Figure
7-11). When ordering, specify part number 7002-7A377-ffff (ffff = the assigned frequency for the
coupler).
