Signal converters perform the coupling function for analog signals on both the input side and the output side. They are indispensable when processing analog values with electronic controls. Under harsh industrial conditions in particular, it is often necessary to transmit analog signals over long distances. Electrical separation is then needed as a result of the different power supplies. The resistance of the wiring causes potential differences and losses which must be prevented.

Electromagnetic disturbance and overvoltages can affect the signals on the input side in particular or even destroy the analog modules. All terminals of the 3RS70 signal converters are safe up to a voltage of 30 V DC and protected against reverse polarity. Short-circuit protection is an important function for the outputs above all.

The devices are EMC-tested according to

IEC 61000-6-4 (generic standard for emitted interference)
IEC 61000-6-2 (generic standard for interference immunity)

The analog signals comply with

IEC 60381-1/2.

Область применения

Signal converters are used in analog signal processing for

Electrical separation
Conversion of normalized and non-normalized signals
Amplification and impedance adaptation
Conversion to a frequency for processing by a digital input
Overvoltage and EMC protection
Short-circuit protection of the outputs

3RS7025 manual / automatic transformer

For special applications in which analog signals have to be simulated, or during plant commissioning when the actual process value is not yet available, the 3RS7025 devices feature an adjustable potentiometer for manual setpoint selection and a manual/automatic switch.

The potentiometer for the 3RS7025 devices is used to simulate analog output signals when the changeover switch is set to "Manual" and the control supply voltage is applied, without the need for an analog input signal, and the scale ranges from 0 % to 100 %.

Example: When it is set for an output of 4 mA to 20 mA, the 0 % scale value on the potentiometer represents an output current of 4 mA and the 100 % scale value represents an output current of 20 mA. In the "Auto" switch position, the output signal follows the input signal proportionally regardless of the potentiometer setting.

Application example: Analog signal processing
