DESCRIPTION
The following is a description of the faceplate LED, field termination
connectors, andelectrical characteristics of the fieldconnections.
2.1 Mechanical Description
The Current Input module is a MultibusĆcompatible printed circuit
boardassembly that plugs into the backplane of the DCS
5000/AutoMax or AutoMate rack.
It consists of a printedcircuit board, a faceplate, anda protective
enclosure. The faceplate contains tabs at the top andbottom 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 labeledCh.0Ć15". See figure 2.1.
Analog input signals are brought into the module via a 5Ćfoot
multiĆconductor cable assembly. The 37Ćpin male DĆshell connector
endof the cable attaches to the faceplate connector, while the 37Ćpin
female DĆshell connector endof the cable attaches to the male
connector on the terminal boardassembly (M/N 61C549 or
M/N 61C550). 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.
