SIRIUS 3RS70 signal converter. The Siemens Sirius 3RS70 signal converters perform the coupling function for analog signals on the input and output side. They are essential when processing analog values with electronic controllers. Especially under harsh industrial conditions, it is often necessary to transmit analog signals over long distances. Due to the different power supplies, electrical isolation is required in the process. The resistance of the wiring causes potential differences and losses that must be avoided. Electromagnetic disturbances and overvoltages can influence the signals especially on the input side or even destroy the analog modules. All terminals of the 3R70 signal converters are safe up to a voltage of 30 V dc and protected against pole reversal. Short circuit protection is a particularly important feature for the outputs. Features and benefits. Small width. Easy to configure universal converter. Converter with frequency output. All series are fully calibrated. Integrated manual/automatic switches with a setpoint generator. Outputs are short circuit protected. Up to 30 V - protected against damage due to wiring faults.
