DESCRIPTION
The following is a description of the faceplate LED, field termination
connectors, and electrical characteristics of the field connections.
2.1 Mechanical Description
The Voltage Input module is a MultibusĆcompatible printed circuit
board assembly that plugs into the backplane of the DCS
5000/AutoMax or AutoMate rack.
It consists of a printed circuit board, a faceplate, and a protective
enclosure. The faceplate contains tabs at the top and bottom to
simplify removing the module from the rack. On the back of the
module are two edge connectors that attach to the system
backplane. Module dimensions are given in Appendix A.
The faceplate of the module contains one 37Ćpin female DĆshell
connector socket labeled Ch.0Ć15". See figure 2.1.
Analog input signals are brought into the module via a 5Ćfoot
multiĆconductor cable assembly. The 37Ćpin male DĆshell connector
end of the cable attaches to the faceplate connector, while the 37Ćpin
female DĆshell connector end of the cable attaches to the male
connector on the terminal board assembly (M/N 61C547 or M/N
61C548). ScrewĆtype connectors on the terminal board assembly
provide for easy field wiring.
The module faceplate also contains a green LED labeled OK". This
LED is on when the module has passed its powerĆup diagnostics and
is operating properly.
