For all four inputs, the anodes and cathodes of the optocouple LEDs are accessible, just as the emitters

and collectors of the four output optocouplers.

There are no additional components on the I/Os besides the optocoupler pins. If, because of excessive

overvoltage and/or reversed voltage a coupler breaks, they can be easily replaced because they are sock-

eted.

8.3.1 Optocoupler technical data

8.3.2 Input wiring (e.g.: light barrier) with NPN-transistor

The following schematics shows the wiring:

OK1 is the optocoupler on Inspecta-5; R1 and the transistor (e.g.: the light barrier containing this tran-

sistor enthält) are external components.

R1 has to be calculated so that the LED current is between 10..16mA: R1 = (U-3V) / 16 mA

e.g.: U=24V: R1 = (24V - 3V) / 16 mA = 1,3125 kOhm (chosen: 1,5 kOhm)
