The ABB 1SVR011705R2100 is a DIN rail-mounted interface relay with a 110-240V AC supply, designed to bridge control signals between different voltage domains or signal types in an industrial panel. Its key feature is universal configurability: the input accepts either a 0-5V or 0-10V signal, and the output mirrors that same range, making it a straightforward signal repeater or isolation stage for PLC analog cards or sensor transmitters.
The 110-240V AC supply range covers standard single-phase control voltages across most regions — 120V in North America, 230V in Europe — without needing a separate transformer tap. Snaps onto standard 35mm DIN rail; allow at least 10mm clearance above and below for airflow and wiring access. Because the input and output ranges match (both 0-5V or both 0-10V), this relay acts as a galvanic isolation buffer rather than a signal converter. If you need a voltage-to-current or range-shifting function, this part won't do it — it passes the same signal type through.
