Installation
3.6 Expansion Card Connections
The sc1000 controller system can be expanded with internal plug-in expansion cards.
Each expansion component has an address on the sc1000 network and can be
programmed as required. The address number is located on the card.
Refer to the Plug-in Expansion Card Instruction Sheet (Cat. No. 6179589) for installation
instructions.
It may be necessary to remove an existing expansion card, if the expansion card is
blocking access to certain connectors. Refer to
Removing an Expansion Card on page 30
for more information.
When an instrument is ordered, it comes pre-installed with the appropriate plug-in
expansion cards (
Figure 19 and Figure 20 ). The following options can be connected:
• Relay card with 4 relays
• Digital field-bus cards—Modbus (RS485), Profibus DP, etc.
• mA output card with 4 outputs
• mA input card with 4 inputs (analog or digital)
• sc-sensor connectors
