5.7 INPUTS
There are two optocoupled polarity insensitive inputs available on the SC4000: Input 1
(External Trigger Input) and Input 2, a generic input. These inputs are typically used when
SC4000 is an ID-NET Master in a Synchronized network.
These inputs are optocoupled and can be driven by both NPN and PNP type commands.
NOTE
Polarity insensitive inputs assure full functionality even if pins A and B are
exchanged.
