The Siemens SIRIUS 3RS7003-2AE00 is a single-range signal converter that accepts a 4-20 mA analog input and provides an isolated output, powered by a 24 VAC/DC supply. It is designed for one channel of signal conditioning in a control panel, converting a process variable current loop into a usable signal for a PLC or indicator. Snap-on mounting to a DIN rail and IP20 protection mean it lives inside an enclosure, not on the machine frame. The 6.2 mm width packs tightly on the rail — useful when retrofitting a signal conditioner into a crowded panel without re-laying the whole terminal block. An LED on the face confirms the unit is powered and operating, which speeds troubleshooting on a live line without needing a meter.
The 4-20 mA input is the standard current loop for process transmitters (pressure, temperature, flow). This converter conditions that signal, so it is the right pick for any panel receiving a 4-20 mA field transmitter signal. Rated supply is 24 V at 50/60 Hz AC or DC, consuming 0.29 W. That is low enough to daisy-chain multiple units from a single 24 VDC power supply without exceeding its budget. Isolation between input and output (listed as 'Between Input And Output: Yes') means the field loop is galvanically separated from the control side, preventing ground loops that can drift a 4-20 mA signal. The 72.5 mm depth and 93 mm height fit standard DIN-rail enclosures; the 6.2 mm width is a single module width, so it takes up minimal space.
