PRL_NZ Posted April 13, 2021 Report Share Posted April 13, 2021 Hi I am trying to drive a Gecko Stepper Drive from a UNISTREAM PLC I have the UID 0808-THS (PTO) module and the Gecko drive already so I am to some degree committed to these components. The issue is that the Gecko only works with a 5V input and my understanding is the PLC only outputs 24V? is this correct or when you configure the system to run as a PTO it switch to a NPN type contact with no Voltage? Does the OUTPUT O0 and O1 turn into a NPN type connection that can have its own power supply or will they still produce a 24V PTO signal when activated? I have looked at Transistors and MOSFETS but all seem to drive the other way Lower Voltage to Higher not Higher voltage to lower voltage. Any help would be greatly appreciated. Only other thought was a simple voltage divider of (O0) 360ohm ^ 90ohm (CM2) tapped in the middle to produce a 5V signal (metal oxide so I can dissipate 5W) but my raw electronics is a bit rusty to test on system. Any help, or advice would be greatly appreciated. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
