7.1 Input Wiring
Each input is optically isolated from the logic circuit. Each input is independent of the other inputs and
can be wired different. Each input has two connections at the IP I/O connector, Input x + and Input x -.
However the TIP670 has AC optocoupler at the input side. Therefore the polarity of the input signal
may be either way.
