The Universal X1-NIS-UNI-01 module is a high integrity interface suitable for applications requiring SIL 3 or SIL 2 level (depending on applications) in safety related systems for high risk industries. Thanks to its high flexibility, it can interface 2-wire active/passive 4-20 mA (AI), smart positioners (AO), switches and proximity detectors (DI), as well as solenoid valves and other process control devices (DO). HART® communication is supported for both active and passive transmitters, and I/P. The module always sinks current and the Termination Board extends its use to source loops. Programmable line and load open/short circuit detection and out-of-range current fault is also provided. The module automatically matches the application, without reprogramming; if required, it can be re-calibrated through the configuration software. To ease maintenance operations, field devices can be disconnected through a two-position insertion/extraction mechanism. This product requires a dedicated Termination Board.SIL 3/2 depending on applications / SC 3Installation in Zone 2 / Division 2Loop disconnection to ease maintenance operationsSuitable for AI, AO, DI and DO applications without configurationHART® compatible (passive and active AI/AO loops)Line & Load short/open circuit programmable diagnosticsOut-of-range fault with programmable thresholdsDigital calibration available through configuration softwareInput and Output short circuit proofField fault mirroring to the DCS/PLC UNI CardHigh AccuracyThree port isolation, Input/Output/SupplyTechnical Specifications:AI Power dissipation: 0.8 W (pass.
