Installation
3.5 DIN rail expansion modules
The sc1000 controller can be expanded with DIN rail expansion modules.
The following DIN rail module options can be installed:
•
Base module (for connecting power, sc1000 network and display module)–The base
module is required for the installation of expansion modules on the control cabinet.
•
Relay card with 4 relays
•
mA output card with 2 outputs
•
mA input card with 2 inputs (analog or digital)–One base module can provide up to
2000 mA of power to the other modules connected to it on the DIN rail.
The total number of modules that can be connected together is limited by the power
supply from the base module. Up to 13 communication modules can be attached to each
base module. When more than 13 communication modules are needed, a second base
module must be connected through the sc1000 network.
for more information about the DIN rail expansion
modules.
3.6 Expansion cards
The sc1000 controller can be expanded with internal plug-in expansion cards. Each
expansion component can be identified with its serial number on the sc1000 network and
programmed as required. The serial number is located on the card.
It may be necessary to remove an existing expansion card, if the expansion card is
blocking access to certain connectors. Refer to
for more
information.
When an instrument is ordered, it comes pre-installed with the appropriate plug-in
expansion cards. The following options can be connected:
•
Relay card with 4 relays
•
Digital field-bus cards (Modbus (RS485), Modbus (RS232), Profibus DP)
•
mA output card with 4 outputs
•
mA input card with 4 inputs (analog or digital)
•
sc-probe connectors

The expansion modules for control cabinet installation use the 24 VDC power supply in the
control cabinet. Make sure that the correct power supply is provided. Install a residual current
circuit breaker. The modules have an environmental rating of IP20 and must always be mounted
in an enclosure suitably rated for power and environment.
