Extended Feature Option Cards - Zener MSC-3 Instruction Manual

Extended Feature Option Cards

The MSC-3 may be fitted with 1 or 2 extended features cards. Each card provides additional analogue
and digital inputs and outputs. The cards may be fitted 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
Each extended feature card for the MSC-3 makes available a single analogue output for those
applications that require feedback of an internal signal. The analogue output is designed with the
following features:
• Configurable voltage (V) or current (mA) input configuration.
• Signal source selection
• Easy to configure spanning and translation.
