Good morning folks!,
I need to drive two relays connected to both DIOs at my TS-7200. Due to the
sink at these lines are 4mA ( 3,3V ), will need to drive them by using
optocouplers. Any idea of which PN I Could use?, FYI, the Ic at the output
stage, would have to drive a 260R coil ( around 40mA )
The second part of the question ( or the other question ) is:
Need to connect a 16x2 display at the Display port. I TS port has direct
connection to the display ( based on a HD44780 ). My question is related to the
contrast adjustment pin, which in the TS is biased to ground thru a 620R
resistor. How should I connect this pin to the display one?
Thank you very much for your help...
Marcos
