Can this model be used for over-temperature protection?
I would like to speak with a technical rep regarding the operation of the CN74-3 temp controller. I am Working from Home (WFH). I do not have controller in front of me (located 34 miles from here).
I'm confused what the "relay" output means. Does that mean that I do not need a separate solid state relay? My understanding was to use this and connect the output to a SSR, however I am now now sure
For the CN745, I did not see an "Output" option in the Communication Parameters List. Does this exist?
Is the relay output just a simple on/off signal? Is the DC Pulse a PWM signal, and, if so, what is the duty cycle and frequency range?
for CN745, the product does require any solid state relay? I am not sure that in case of current output control any solid state relay is required. Could you recommend any solid state relay or items which are required to be purchased with the CN745?
