Connections/cables for the CDM 490 Connection Module
The CDM 490 Connection Module is suitable for connecting
one CLV without/with heater
to peripherals (distribution function) and the power supply. The module can be used to es-
tablish a connection to the host (point-to-point), to integrate the device in a SICK CAN Scan-
ner 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 10.13.2 Connection modules, Page 10-75
Optional modules for building-in into the CDM 490:
•
CMP 490 Power Supply Module in optional cover for supplying the CLV without heater
directly from an AC power line
•
CMC 400 Connection Module Cloning for saving the parameters of the CLV externally
•
CMD 400 Connection Display Module in optional cover for representation of reading re-
sults and reading diagnosis data
•
CMF 400 Bus Modules (field bus gateways) for connecting the CLV to Profibus DP,
DeviceNet or Ethernet TCP/IP
The CMP 490 Power Supply Module can not be used if the CMD 400 Display Module has
always been built-in (or vice versa).
For detailed description of function and installation see the corresponding Fitting/Operating
Instructions (see
Chapter 10.15 Supplementary documentation, Page 10-82
shows the connection principle of the CDM 490.
The procedures for connecting and configuring the connection module are described in the
"CDM 490 Connection Module" Operating Instructions
(order no. 8 010 005, German/
English).

Diagrams showing you how to connect the CDM 490 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 CLV 490. The software can also
