SIL3 2-Wire Passive/Active HART® Tx Current RepeaterThe Current Repeater Power Supply X1-NIS-AI-01 module is a high integrity analog input interface suitable for applications requiring SIL 3 level in safety related systems for high risk industries. It provides an isolated supply for energizing conventional two-wire passive 4-20 mA transmitters, while repeating the current to the system card. Two-wire active transmitters are also supported. The circuit allows bi-directional HART® communication for both passive and active devices. The module always sinks current and the Termination Board extends its use to source loops. An out-of-range current fault according to IEC 60947-5-6 NAMUR NE 43 standard is available with limits configurable through the optional Gateway. To ease maintenance operations, field devices can be disconnected through a two-position insertion/extraction lever mechanism. This product requires a dedicated Termination Board.FEATURESSIL 3 / SC 3Installation in Zone 2 / Division 2Loop disconnection to ease maintenance operations4-20 mA 2-wire Active-Passive InputHART® compatibleOut-of-range fault according to IEC 60947-5-6 NAMUR NE 43Input and Output short circuit proofHigh AccuracyThree port isolation, Input/Output/SupplySTATUS: ACTIVECHANNELS: 1GeneralPower Dissipation0.55 W (passive Tx), 1.05 W (active Tx) @ 24 Vdc with 20 mA, 24 Vdc + 250 Ω output, typical.System SupplyVoltage24 Vdc nom (18 to 30 Vdc).Current Consumption23 mA @ 24 Vdc with 20 mA, typical.System OutTypeCurrent 4 to 20 mA.
