Option 050 - Digital lnput ModeSpecificationsSpecifications for the 16 Channel Isolated Digital Input/lnterrupt assembly follow.Specifications are performance standards, or limits, against which the assembly maybe tested.OPTION 05018 CHANNEL ISOLATED DIGITAL INPUTIINTERRUPT ASSEMBLYlnput Signal CharacteristicsInput Max. Input Min. InputLevel V&ax.I VMllmin.) Voltage Currant15 volt level is standard, 12 and 24 volt levels arejumper selectable. Other voltage levels can be acceptedusing customer supplied resistors).Maximum Isolation Voltage: 4 170V peak between any inputterminal and ground.Digital lnput Moda IBits 0.151Logic Polarity: Positive True(Negative True is jumper selectable)Handshaking: Gate and Flag Lines are optically isolated. Gateoutput is open collector. Flag input is identical to inputlines. Polarity of gatelflag is jumper selectable. The assemblymay be configured to operate with no handshaking.Interrupt Moda IBits 0.7)Minimum Pulse Width: 100 microsecondsTriggering: Each interrupt line is individually programmable forpositive or negative edge triggering.Masking: Each interupt line may be enabled or disabled using aprogrammable mask.Multipla Interrupts: Multiple interrupts are latched and are dealtwith at a computer dependent rate.Interrupt Timing: The Option 050 assembly will respond to aninterrupt within 1 millisecond of a programmed interruptcondition change.Five Volt Supply: Source up to 20 mA per assembly.Operating Consideration: Digital lnterrupt (SRQ) is notavailable in the 3498A Extender.Artisan Technology Group - Quality Instrumentation ...
