Control by data transfer.
When controlling is realized by data transfer, following possibilities can be choice:
- standard line RS 232 or bus RS 485 or CAN (also optically insulated – see specification)
- or RS 232 line with TTL level (advantage fr direct communication processor – processor). Controller cooperates with 3.3V systems, as well
as with 5V systems. In this case line is defined like this:
Controller sends data with 3.3V level.
Controller receives correctly data from control system with 3.3V level, as well as 5.0V level.
Control by input PWM.
Control signal definition:
Control information is Pulse width.
Controllers without galvanic isolation for input PWM:
Controllers with galvanic isolation for input PWM:
