The ABB 1SVR011700R0000 is an interface relay — a signal-conditioning module that takes a low-level analog input and reproduces it as an isolated analog output. The unit accepts either a 0-5 V or 0-10 V input signal and outputs the same range, making it a straightforward 1:1 signal repeater or buffer for PLC analog cards, transmitters, or remote I/O.
The 24 V DC supply rail is the only power needed — no separate loop supply for the output. The input impedance is high enough that it won't load a typical 0-10 V sensor or controller output. The output drives into a standard analog input card without additional amplification. Because the input and output ranges are identical (0-5 V or 0-10 V), this part is a buffer or isolator, not a converter. If you need to translate 0-10 V to 4-20 mA, this is the wrong module.
Allow a few millimeters of clearance above and below for terminal access — no forced-air cooling required at the low power levels involved.
