X1-IS-AI-01-S
I.S. SIL3 2-Wire Passive/Active HART® Tx Current Repeater

The Current Repeater Power Supply X1-IS-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 located in Hazardous Area, 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.
