Extended Feature Option Cards
The MSC-3 may be tted with 1 or 2 extended features cards. Each card provides additional analogue
and digital inputs and outputs. The cards may be tted in either the left or right option card sockets.
The MSC-3 will detect the presence of the option cards and commence exchanging I/O status data.
Additional options will appear in the selection lists and accesses to additional menus are available for
extended feature set up.
Extended Feature Analogue Output

following features:
• Congurable voltage (V) or current (mA) input conguration.
• Signal source selection
• Easy to congure spanning and translation.
