Setup & Operation 7.2 Protected Expansion I/O Board (Expansion I/O Board - Optional)RC420 Rev.9 517.2.2 Protected Expansion I/O Board : Input CircuitThe following diagrams illustrate cases where #48 through #79 (for the first ExpansionI/O Board) are assigned to the Protected Expansion I/O Board’s (or Expansion I/OBoard’s) inputs and outputs. The I/O number assignment depends on the controllersoftware settings.Input Voltage Range : + 12 V to 24 V ±10%ON Voltage : + 10.8 V (Min.)OFF Voltage : + 5 V (Max.)Input Current : 10 mA (TYP) at + 24 V inputCAUTION■ Use the PNP-type of wiring diagram for CE conformance. Be sure to wirecorrectly. Improper wiring may cause safety problems as it may make theManipulator move unusually.Protected Expansion I/O BoardTypical Input Circuit Application 1: NPN(Same)(Same)(Same)(Same)(Same)(Omit)GND +DC1 Input No.48 to 51 common3 Input No.484 Input No.495 Input No.506 Input No.5151 Input No.52 to 55 common53 Input No.5254 Input No.53~~~2.2 kΩ470 Ω
