CBX ELECTRICAL CONNECTIONS

INPUTS

NOTE
There are two opto-isolated polarity insensitive inputs available when the reader is con-
nected to the CBX: Input 1 (External Trigger) and Input 2, a generic input:
The External Trigger can be used in One Shot Mode or in Phase Mode. Its main functions
are:
•
•
The main functions of the general purpose Input 2 are:
•
•
The electrical features of both inputs are:
V = 30 Vdc max.
AB
I = 12 mA (CAB-1011) + 12 mA (CBX) max.
IN
The active state of these inputs are selected in software.
An anti-disturbance filter, by default, is implemented in software on both inputs. The
value can be changed through the software parameter Debounce Filter. See the Help On
Line page of the Reading Phase step (Inputs) in DL.CODE for further details on these
parameters.

When Inputs 1 and 2 are connected through the CBX connection box,
they become opto-isolated and polarity insensitive and acquire the elec-
trical characteristics listed below. To function correctly, they require
setting the Input Line Type configuration parameters to NPN for the
respective input. The hardware connection to the CBX can be either NPN
or PNP.
