The Siemens 3RS7000-1CE00 is a SIRIUS single-range signal converter that takes a 0... 10 V input and outputs a proportional 0... 20 mA current loop signal. It is a 1-channel active device, meaning it generates its own loop current rather than relying on a passive external supply. Snap-on mounting to a DIN rail, IP20 finger-safe housing, and a 6.2 mm width let it fit into tight control panel rows alongside other SIRIUS modular components.
The 0.015 %/°C temperature drift means the output shifts less than 0.15 % over a 10 °C swing — fine for most process signals, but if your panel sits near a heat source or in direct sun, that drift adds up and may need a tighter-spec converter. The 20 mV maximum voltage ripple on the input side tells you the converter rejects supply noise down to that level; a noisier rail will pass through as output error. Active power consumption is 0.29 W, negligible in a multi-device panel but worth noting if you are counting watts on a 24 VDC supply budget.
Zero clearance needed on all sides — upwards, forwards, backwards, downwards, and at the side all read 0 mm — so you can pack modules tight without worrying about ventilation gaps. Mounting position is any orientation. The 72.5 mm depth and 6.2 mm width mean it occupies about one standard terminal-block slot on the rail. Wire termination accepts 1 x (20... 14) AWG solid conductor.
