Product description

The DT1300 … Intrinsically Safe Isolators / Power Supplies provide signal transmission between transmitters operate in zone 0, zone 1 potentially explosive area and the signal processing units operate in the safe area.
The DT1300 … family galvanically isolate the input, the output and the power supply.
The intrinsically safe input signal may be 0-20 mA, 4-20 mA, 0-10 V, the output signal also may be 0-20 mA, 4-20 mA, 0-10 V.
The isolators available with two different transmitter supplies (17 VDC or 18 VDC). The safety data these two types differ considerably from each other, thus they can be flexibly matched to the various transmitters. The transmission parameters of the isolators are outstandingly good: the non-linearity is < 0.01% and the temperature coefficient is < 50 ppm / °C.
The supply voltage range is 19-29 VDC, thus the isolators are insensitive to the supply voltage change.
