Connections/cables for the CDM490 Connection Module
The CDM490 Connection Module is suitable for connecting
one CLV490 without/with
heater
to peripherals (distribution function) and the power supply. The module can be used
to establish a connection to the host (point-to-point), to integrate the device in a SICK CAN
Scanner Network or in field bus systems. The module is available in one variant and can be
operated without optional modules (see below) with an operating temperature to –35
°
C
(–31
°
F). For technical data see
Chapter 10.13.3 Accessories: Hoods, Page 10-75
.
Optional modules for building-in into the CDM490:
•
CMP490 Power Supply Module in optional cover for supplying the CLV490 without
heater directly from an AC power line
•
CMC400 Connection Module Cloning for saving the parameters of the CLV490 exter-
nally
•
CMD400 Connection Display Module in optional cover for representation of reading
results and reading diagnosis data
•
CMF400 Bus Modules (field bus gateways) for connecting the CLV490 to Profibus DP,
DeviceNet or Ethernet TCP/IP
The CMP490 Power Supply Module can not be used if the CMD400 Display Module has
always been built-in (or vice versa).
For detailed description of function and installation see the corresponding Fitting/Operating
Instructions (see
).
shows the connection principle of the CDM490.
The procedures for connecting and configuring the connection module are described in the
"CDM490 Connection Module" Operating Instructions
(order no. 8010005, German/
English).
Note
Diagrams showing you how to connect the CDM490 Connection Module are also available
in the “CLV Connect“ PC program. This software is available on the “Manuals & Software“
CD-ROM, which is included in the scope of delivery of the CLV490. The software can also
