RIS SC-1302-INV Industrial Isolated Transmitter

RIS SC-1302-INV Industrial Isolated Transmitter is an AMETEK Rochester Instrument Systems isolated transmitter that converts a signal from a voltage or current input into a 4–20 mA isolated loop output, ensuring galvanic isolation between the input and the output. Designed for process control and factory automation, it accepts either voltage or current inputs and translates them to a standard 4–20 mA signal suitable for PLCs and DCS instrumentation. The unit can be powered from either 115 V AC or 24 V DC, with isolation options between the power path and the signal path; the SC-1302 family supports both isolated and non-isolated power configurations. Key performance figures include a 130 dB common-mode rejection at 60 Hz and a power-supply effect of ±0.15% for ±20% power variation with an 800 Ω load and a 4–20 mA output. Operation spans 0 to 140°F (-18 to 60°C) ambient temperature, making it suitable for harsh industrial environments. Enclosures range from a single-unit surface-mount option to 19" rack-mount configurations, with NEMA 4/12 protection and FM-approved explosion-proof variants for Class I, Division 1 locations. This transmitter is ideal for sending field sensor signals to control systems while preserving signal integrity in electrically noisy environments.
