I have a 30 year old Symax PLC. Lately two of the outputs are putting out approx. 8vac continuously without the output being energized. All the outputs operate are indicator lights, which are glowing real dim (it's 120vac indicator lights, very low wattage).
What can I use to draw the voltage down to zero when the output is not in use?
I've replace the output card 3 times without any change to the output voltage.
Is it possible that the rack may be going bad and causing this low voltage output continuously? All the other outputs on the same card are reading zero volts.
Thanks for any help,
Dave
