The Current 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 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.
