Could someone help. Im using a mydaq. I have built a home alarm system for a school project. The PIR sensor works fine. However, I am using a magnetic switch for the door. It works fine when the switch is made, but when the switch is low ( the door is open) it gives an error 201381 saying--- One or more connections to external power rails are drawing too much power. The operation has been aborted to prevent the device from using too much power. Remove the connection(s) to the external power rails and restart your task.---.
Does anyone have any ideas.

It sounds like the switch is drawing more power than the myDAQ can supply. I'd check the specifications/datasheet of the switch and the myDAQ to ensure that the myDAQ is capable supplying the amount of power that the switch requires.
