RIS AMETEK XSC-1326-89093C Isolated Millivolt Transmitter

The AMETEK RIS XSC-1326-89093C Isolated Millivolt Transmitter is a dedicated signal conditioning device designed to interface very low-level millivolt signals with standard control and monitoring systems. It accepts a DC input in the 0–50 mV range and provides galvanically isolated transmission to a higher-level interface, enabling safer, more reliable data transfer from sensitive sensors in industrial environments. The unit is powered from a 230 VAC supply at 50/60 Hz, simplifying integration into typical plant electrical infrastructures. Encased in a compact enclosure measuring 3 x 9 x 6 inches, the transmitter is sized for installation alongside other field devices in control panels or trunk lines. This particular part number, XSC-1326-89093C, is a variant of the SC-1326 family and is listed as discontinued by the manufacturer, which is important to consider for long-term maintenance or replacement planning. In practice, it serves applications where small sensor outputs—such as those from precision millivolt sensors or low-level transducers—must be electrically isolated from the control system to minimize ground loops and noise, while delivering a reliable, scalable signal suitable for acquisition, display, or process control. When selecting this model, engineers typically pair it with instrumentation that requires robust isolation and compatibility with 230 VAC power, ensuring a straightforward retrofit for legacy systems or new installations that rely on precise millivolt-level measurements.
