AMETEK SC-1302-H3-A12 Transmitter

AMETEK SC-1302-H3-A12 is an isolator transmitter from Rochester Instrument Systems that converts a 1–5 V DC input into a 4–20 mA output while maintaining galvanic isolation between the input and output circuits. Powered from 115 VAC (50/60 Hz) via an on‑board transformer, it supports standard industrial control loops and can drive loads up to 800 Ω at 4–20 mA. The model SC-1302-H3-A12 carries the stock number 263141. This transmitter interfaces low‑level voltage signals with 4–20 mA process controllers or automation controllers, enabling reliable signal transmission over distances and preventing inter‑circuit interference. It is part of AMETEK Rochester Instrument Systems’ SC‑1300/SC‑1302 family of signal conditioners and transmitters, designed for rugged industrial environments with a compact form factor suitable for panel mounting in control cabinets.
