STAHL 9160/19-11-10S TRANSMITTER SUPPLY UNIT EX I FIELD CIRCUIT 214901

Product Code: 214901

The Stahl Series 9160 Transmitter Supply Unit is a versatile and precise solution for hazardous area automation interfaces. This single-channel unit operates in transmitter supply and repeater modes, supporting an auxiliary power range of 18 to 31.2 V AC/DC. It features an isolation amplifier and transmitter power unit with an input function capable of handling 0/4 to 20 mA signals with HART communication. The output functional range is equally robust, offering 0/4 to 20 mA with or without HART. Designed for reliability in extreme conditions, it operates within a temperature range of -20°C to +70°C and boasts an IP30 rating. Installation is simplified with screw terminals and compatibility with Zone 2 environments. The unit's universal design accommodates both two- and three-wire transmitters as well as mA sources including four-wire transmitters. Engineered for high accuracy, the standard model meets SIL 2 requirements, while a special version is available for applications requiring up to SIL3 compliance according to IEC/EN 61508 standards. This makes the Stahl Series 9160 an ideal choice for engineers seeking dependable performance in challenging industrial settings.
