I have two cfp-2220 that I want to connect with each other using the DIO's of 5V that they have.
The problem that I have is that I don't know the impedance to connect the CFP2220-1 Digital Output 1 to a relay for switching the CFP2220-2 Digital Input 1.
I am using a relay for interfacing the signal. This relay needs 34mA 5V to operate. I am not sure if the CFP2220 would have the needed power to turn the relay on and to close the contact that will operate the CFP2220-2 Digital Input 1. In the user manual of the CFP2220 does not mention anything about it.
