The Siemens 3RS7000-2CE00 is a SIRIUS single-range signal converter that takes a 0... 10 V input and provides an isolated output, powered by a 24 V AC/DC supply.
The 0.8... 1.1 range at DC and at AC 50/60 Hz defines the adjustable threshold window for the input signal — you set the switching point within that band relative to the 0-10 V input. The 30 V input voltage rating is the maximum continuous input the converter can tolerate. With a rise time of 6 ms, this converter is suited for monitoring applications where a few milliseconds of delay are acceptable, not for high-speed counting or fast fault detection. The 72.5 mm depth and 93 mm height are standard for this class of SIRIUS component, so it aligns with adjacent devices on the rail. It consumes 0.29 W active power, negligible for panel power budgeting. The LED display version gives a visual status indication on the front.
Signal converters like this one are used in control panels to translate a sensor or transmitter's voltage output (0-10 V) into an isolated signal for a PLC analog input, or to condition a signal for a display or recorder. The galvanic isolation between input and output breaks ground loops and protects the receiving device. The any mounting position flexibility simplifies panel layout.
