Hello folks,
I have an old Omega CN-9121 PID Controller and a 105Watts 115V Fibre heater mantle with an inbuilt K-type CHromel-Alumel temperature thermocouple also attached into it. I plan to use the PID controller to control the temperature of the heater. Looking at the manual below:
Manual for PID
I decided that I wanted to use the inbuilt SP2 relay in the PID controller. From the wattage of the heater, I know it would draw a maximum of only 1A and is going to be below that. The SP2 output from the PID has a small 5V energized relay with 3A load capacity. I would like to know if it is safe to use the heater directly with the SP2 relay terminals of should I use the SP2 relay to run another AC relay for the heater?
Thanks in advance,
R
