Siemens 3RS7005-2FE00 Amplifier

Siemens 3RS7005-2FE00 is a single-channel separation amplifier (signal isolator) designed for DIN-rail mounting in 24 V AC/DC control cabinets. It provides a 3-way input: 0–10 V or 0/4–20 mA, and a matched isolated output of 0–10 V or 0/4–20 mA, enabling galvanic isolation between the sensor and the controller. The unit runs from 24 V AC/DC, uses spring-type push-in terminals, and features a LED display for local readout; it consumes about 0.29 W and supports an input signal up to 30 V with a rise time around 6 ms. This Siemens device is typically used to interface analog sensors to PLCs or automation controllers, delivering signal conversion and isolation in 24 V environments.
