LSI-16/LSI-16e REAR PANEL
General Purpose Inputs
These connections provide functionality of the option inputs on the LSI-16e or of the LSI-16 that has been upgraded with an Interface
Module (IM-16). On an LSI-16 without an option board, these connections will remain inactive.
Two connectors, labeled Option A and Option B, are located on the back of the LSI-16e. Each slot consists of 14 pins which are
labeled 1 to 14. Each connector bank allows for the following connection:
• Chassis Ground: One connection per connector bank.
• Isolated Ground: Four connections per connector bank.
• Control Inputs: Eight connections per connector bank.
24 Volts DC - One output per connector. Internally sourced, this will allow up to 60mA to be shared over all general purpose inputs.
