Task

Integration of three L2000 (L27) family single-beam photoelectric safety switches in a UE410-8DI input expansion unit.

Function

The sensors switch when the light beam is clear. When sensor 1 and sensor 2 switch, the input condition for input A is met. When

sensor 3 has switched, the input condition for input B is met. If a light beam is interrupted, the related input condition (input A or in-

put B) shuts down the UE410-8DI.
