Isolated digital I/O expansion card The 5624 card accepts switch closures, PLC and 12V logic inputs and other voltages that can not be used with standard TTL logic. The card supports 16 input channels and eight output channels. The inputs have 500V of isolation to ground and 100V between chan- nels. The eight output channels will drive relays, lamps, small motors, and solenoids. Each channel can switch loads up to 200 mA and 50V. Signals may be AC or DC. Each output is isolated from each other and the system. As shipped, the 5624 will accept signals from 2.7–14V DC. Plug–in resistor packs allows the user to accommo- Octagon products are designed and date ranges from 3V to 84V. manufactured under the supervision of an ISO 9001–2000 certified quality management system. Micro PC cards plug into any ISA expansion slot or Micro PC card cage. The Octagon family of Micro PC controllers, expansion cards, and card cages provide a complete solution for applications in transportation, security, military, communications, distributed control, Features point–of–sale, ticketing machines, weighing equipment, DIGITAL I/O: and other similar applications. � 24 high–voltage I/O lines; 16 input lines, 8 output lines The 5624 will withstand high shock and vibration, and � Protected from accidental reverse polarity operates in temperature ranges from –40° to +85° C.
