The Siemens 3RS7002-2CE00 is a SIRIUS single-range signal converter — a 1-channel device that accepts a 0... 20 mA analog input and provides an isolated output, powered by 24 V AC/DC. It's an active design, meaning it generates its own output signal rather than just passing through a loop-powered signal. The 0.29 W active power consumption is low enough to ignore in a crowded panel's thermal budget. Galvanic isolation between input and output is present, which prevents ground loops from coupling noise into the control signal — a common headache when routing analog signals across different panels or long cable runs.
The input accepts 0... 20 mA — the standard current loop for process transmitters (pressure, temperature, flow). The 24 V AC/DC supply is universal for most control panels; the 20 mV maximum voltage ripple spec tells you the internal regulation is tight enough that you don't need a separate DC buffer for this converter. The storage and transport range of -40... +80 °C means it can sit in a truck or shelf without issue. The 30 Hz limit frequency and 6 ms rise time indicate this is a DC-coupled signal conditioner, not a fast pulse or frequency converter. It's meant for steady-state analog values, not encoder or high-speed counter signals.
The 6.2 mm width — 0 mm clearance required on all sides — lets you pack converters tightly side-by-side without derating for heat buildup. Terminals accept 20... 14 AWG solid or stranded wire (1 conductor per clamp). The spring-cage style is typical for SIRIUS modules; strip length is standard 8-10 mm.
