Industrial 9260 13-11-10S Transmitter Supply Unit

The STAHL 9260/13-11-10S Transmitter Supply Unit is a compact Ex i field-circuit power module designed to power intrinsically safe measurement devices, including two-wire transmitters and mA sources (with support for 4-wire transmitters) while enabling bidirectional HART communication. This slim device is 12.5 mm wide and available in single- or dual-channel configurations, mounts on DIN rail NS35 (vertical orientation), and uses screw-terminal connections for input/output. Its electrical footprint includes a 24 V DC auxiliary supply and 24 V DC output to field devices, with a nominal form factor of about 112.5 mm in length, 114.5 mm in height, and 12.5 mm in width, weighing roughly 185 g. The enclosure is polyamide rated for IP30, while the terminal block area is IP20, reflecting typical industrial protection levels. Certifications and safety specifications indicate suitability for hazardous locations with ATEX certification (BVS17ATEXE087X) and EU Declaration of Conformity, and it can support safety integrity up to SIL 2 under IEC/EN 61508. The unit is designed for industrial environments, with EMC performance in line with EN 61326-1 and immunity/emission compliance per EN 61000-6-2/EN 61000-6-4, and an operating footprint up to 2,000 m altitude. The 9260 family is intended to provide safe, galvanically isolated auxiliary power for field devices and to support the transmission of HART signals in both directions, making it suitable for hazardous-area instrumentation where compact DIN-rail powered supply and intrinsic safety are required.
