We have a linear actuator to control. This takes 12V, 2A to operate. The plan is to have the Roborio actuate a relay that controls 12V to the actuator. The Roborio relay output specs are 5V and 7.5mA. Digikey offers a million relays with a 5V control signal to the coil but have only a single relay with <7.5mA. It seems like the Roborio relay output is virtually unusable. Am I missing something?
I’m getting two of the TE (Axicom) PB1619-ND which has a 5V, 6.8mA coil that the Roborio can control. It can switch a 12V 1A load. I’ll wire up two in parallel to deliver 2A to the actuator. Its only going to actuate once as a release mechanism for a second so I’m not too afraid of anything overheating.
