Hach Installation and Expansion Modules for SC 1000 Network Card

Installation

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 section 3.6.6 on page 37 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
