General Mach Discussion / Spindle On Off Setup No 5VDC at relay.
« on: April 27, 2011, 12:15:07 PM »
I am trying to set up Spindle on/off. I have Setup output #1 to pin
16 and Spindle on/off to output #1. Checked voltage on Pin 16 and GND
and I get 5VDC. But when I hook up my relay to to it, the voltage
drops down to 0.24VDC. I am using a MDFLY breakout board (generic board) and the relay
has a nominal coil current of 89.3mA. and coil resistance of 56ohms. I
tested relay on computer 5V power supply and it works fine. Do I need
a different relay? Do you know what the problem might be?
