CBX800 INSTALLATION MANUAL
INPUTS
The two optocoupled polarity insensitive inputs, Input 1 (External Trigger Input) and Input 2, a generic input,
available on the CBX800 spring clamp terminal blocks, are managed by the reader connected to the 25-pin
connector.
These inputs are optocoupled and can be driven by both NPN and PNP type commands.
Polarity insensitive inputs assure full functionality even if pins A and B are exchanged.
NOTE
External Trigger Input (Input 1)
The connections are indicated in the following diagram:
