SICK CDB650 - Connecting an External Illumination Unit for the Lector65 X

6.6 Connecting an external illumination unit for the Lector65x
An external illumination unit with a suitable supply voltage range for the Lector65x can
be connected to the connection module, triggered and activated for this purpose in the
Lector65x as follows

Figure 6: Illumination unit without trigger input
Connecting an illumination unit with trigger input
The illumination unit (e.g. ICLxxx) must provide flying leads with 3 wires for connection:
•
Supply voltage
•
GND
•
Trigger input
The trigger input of the illumination unit is connected directly to the switching output
Res 2 or Res 4 of the Lector65x in the connection module (see figure 5, page 18). The
illumination unit is supplied either via a separate external voltage V
S
relative to GND
of the connection module, or via the supply voltage applied to the connection module.
If the illumination unit is supplied via the terminal Uin* of the connection module
(internally protected with a 2 A fuse), the total current for all loads (internal connection
module, Lector65x incl. switching output Res 2 or Res 4, and illumination unit) must not
exceed 1.5 A.
Example: Lector65x consumes 1.05 A at DC 19.2 V with no load at its switching out‐
puts. 1.5 A minus 1.05 A equals a max. available current of 0.45 A for the illumination
unit. If, on the other hand, the non-fused terminal U
in
of the connection module is
used, the customer must protect the supply cables of the illumination unit using a fuse
suitable for the wire cross-section.
