SPECTEC's Model 4029 digital opto-isolated current loop signal conditioner prevents ground loops and interrupts any galvanic signals riding on magnetic speed sensor's output signal.. This signal conditioner converts magnetic, variable reluctance and inductive sensors' sinusoidal signals into a 4-20 mA output suitable for interfacing with process control units, dataloggers, flow controllers, and computers.
The power supply input on the pulse amplifier signal conditioner covers the entire range of commonly used DC power, 7.5 to 30 Vdc regulated, with no selection or adjustment necessary. All inputs and outputs are fully protected against short circuits to supply or ground and reverse polarity supply leads. The circuitry is protected against higher voltages to 50 Vdc.
