2.4 UDL500: Control digital output via hardware triggerInstallation notes: We recommend professional grounding of the device (see 2.1Installation note). Output OUT and Input IN are potential-free. Take care that thegrounding will be sufficient (use second tab connector)!The potential-free input IN may be used to control the reader by a hardware trigger (e.g.tip switch). The control of the potential-free output OUT can be configured within thesoftware. For this the reader has to be operated in trigger mode.In the following example of circuits, the output OUT has not been potential isolated:UDL500 housingV17/01/08 deister electronic GmbH 30890 Barsinghausen Germany 7Wiring & Installation Instructions UDL500
