The Siemens SIRIUS 3RS7003-1CE00 is an active single-range signal converter that takes a 4...20 mA input and outputs a 0...20 mA signal, isolated between input and output. It is part of the SIRIUS product brand, designed for control cabinet integration with snap-on mounting on a DIN rail. The active design means it provides its own output drive, not just a passive pass-through — the output can swing to 0 mA at the low end, which is useful for diagnostics or driving loads that need a true zero-scale signal. The 0.015 %/°C temperature drift keeps the loop stable across the -25 to +60 °C operating range, so the pressure curve or temperature zone you're tracking stays repeatable shot to shot.
At 6.2 mm wide, this converter occupies one slot on a DIN rail — useful when you're packing multiple signal-conditioning channels into a tight panel. Snap-on mounting with no additional fasteners, and it can be installed in any orientation. The IP20 protection class means it belongs inside a cabinet, not in a washdown zone. Clearance requirements are zero in all directions — upwards, forwards, backwards, downwards, and at the side — so you can butt it against other components without derating. The 72.5 mm depth fits standard 80 mm deep enclosures with room to spare for wiring.
