• Analog outputs are available for standard voltage and current signals.
• There are both isolated and non-isolated outputs.
• Optional redundancy is featured, where one type of board can be duplicated to achieve
increased availability.
• A board is offered which combines analog inputs and analog outputs (loop dedicated I/O).
• An output is read out each time new values are entered into the data base.
• Optional software limitations can be selected.
