The ABB 1SVR011701R2500 is a CC-E/RTD temperature signal converter that accepts a universal RTD input and provides a choice of analog output signals: 0-10 V, 0-20 mA, or 4-20 mA, powered by a 24 VDC supply. This is the part you spec into a control panel when you need to bring a resistance temperature detector back to a PLC analog input card as a linear voltage or current loop.
What the output options mean for the loop
The three output ranges cover the two common industrial signal standards: 0-10 V for voltage-input PLC cards and 0-20 mA or 4-20 mA for current-loop inputs. The 4-20 mA variant is the standard for long cable runs and live-zero fault detection — a broken wire drops the loop to 0 mA, which a properly configured input registers as a fault. The 0-20 mA range is less common but useful for legacy systems that lack the live-zero diagnostic.
