Input and module current ratings are with all inputs or s on. te that the figures listed are requirements, t typical. Load requirements for other Series 90-30 PLC components installed in a baseplate must be included in the total load calculations. Load requirements for all Series 90-30 PLC components can be found in GFK-0356, the Series 90-30 Installation nual. Three voltages are listed in the table: +5 provides priry power to operate most interl s +24 Relay Power provides power for s that drive the relays on Relay modules +24 Isolated provides power to operate a number of input s (input modules only).

I/O Installation and Wiring For infortion on installation, remol, and recommended wiring practices for Series 90-30 I/O modules, refer to Chapter 1. Alog Termilogy There are several terms relating to measurements at alog I/O termils that you should be familiar with. Refer to Appendix A for a list of these terms and their definitions. Additiolly, the following pages describe how alog infortion is handled in the Series 90-30 PLC. Specific infortion for individual modules can be found in the description of that module. Hardware Description of Alog Modules Alog modules provide inputs and s with continuous lues, as compared with digital input and modules which have discrete lues of ON or OFF. Alog modules convert digital words to alog sigls, or alog sigls to digital words, depending on whether the module is an module or an input module. Differential Inputs The %AI data table is a storage location within the Series 90-30 where the input infortion is stored. The Series 90-30 PLC has current and voltage alog input modules ailable; however, the Series 90-30 does t recognize a difference between the two types of alog modules. The Series 90-30 PLC system must be configured by the user as described in the Series 90-30 Programble Controller Installation nual, GFK-0356 and the Logicster 90-30/20/Micro Programming Software User’s nual, GFK-0467. After configuration, the four alog input s will correspond to 64 bits in the data table (256 bits for the high-density 16 alog input modules).
