STAHL 9160/19-11-11S TRANSMITTER SUPPLY UNIT EX I FIELD CIRCUIT 220324

Product Code: 220324

The Stahl Series 9160 Transmitter Supply Unit is a versatile solution for hazardous area applications, designed to facilitate transmitter supply and repeater operations within a single channel. This unit operates with auxiliary power ranging from 18 to 31.2 V AC/DC and features an isolation amplifier and active transmitter power unit capable of handling 0/4 to 20 mA signals with HART communication. It delivers an active output in the same range, ensuring compatibility with both two- and three-wire transmitters as well as mA sources including four-wire transmitters. Engineered for precision, this device boasts a high degree of accuracy and operates reliably within a temperature range of -20°C to +70°C. With an IP30 rating, it is suitable for installation in Zone 2 environments. The standard model meets safety integrity level requirements up to SIL 2, while a special version is available for applications requiring up to SIL3 compliance according to IEC/EN 61508 standards. The Stahl Series 9160 is an ideal component for engineers seeking robust automation interfaces and solutions in challenging conditions.
