• Input units are available for standard voltage or current signals, single-ended or
differential, with or without live zero.
• An isolation amplifier is available in the form of a connection unit. The isolation
voltage is 3 kV.
• Some board has reference channels for automatic calibration and testing.
• The data base is updated by scanning, with cycle times normally selected from the
range 100 ms to 600 s.
• Optional software filtering, square-root linearization and deadband limits for updating
can be selected.
• Optional redundancy. Two types of boards can be duplicated to achieve increased
availability.
• A board is offered which combines analog inputs and analog outputs (loop dedicated I/O).

• Different temperature ranges for optimization of measurement accuracy.
• A 13-bit resolution unit is available. This very high resolution requires special precautions
when it comes to cabling. The unit can optionally be used with 12-bit resolution.
