I've encountered a problem that I can't seem to make any logical sense of. Hopefully someone here can help! I have a 24VDC motor with an attached electric brake to prevent back-driving. The motor is controlled with a 5V analog joystick. The joystick has a button that needs to be pressed to activate the motor circuit. I want the same button to also release the brake on the motor. I've installed a relay that has a 5-24VDC control voltage (Part #9938K53 from McMaster Carr). I have the relay wired such that pressing the button applies 5V across the control circuit. This closes a switch that applies 24V to the motor brake. The other wire on the brake ties back into ground (see attached diagram). When I connect the brake to the relay, the brake won't disengage. I've check the brake separately by connecting it to a 24V battery, and that works. I've checked the relay without the brake attached, and the output wires show 24V on my multimeter. However, when I attach the brake, the wires shows exactly 0V on my multimeter and when I press the button it only shows 3.3mV. I can't seem to figure out what the problem is, and appreciate any help or advice anyone can offer.
