9162 series Ex i transmitter power supply units with limit values can be used for the intrinsically safe operation of two- and three-conductor transmitters or for connecting to intrinsically safe mA sources. Two limit values can be easily set using the ISpac Wizard software. If the value exceeds or falls below these limit values, these units will issue an alert. A wire-breakage and short-circuit monitoring system provides increased availability.
- Compact limit value switch with two configurable limit values and output of 4 to 20 mA
- bidirectional HART transmission
- can be used up to SIL 2 (IEC/EN 61508)
