DT1315 intrinsically safe output isolator type designation

Product description

The DT1315 … Intrinsically Safe Output Isolators provide signal transmission between the control equipment and signal sources located in the safe area and actuators, current-to-pressure converters, field process indicators, operate in zone 0, zone 1 potentionally explosive area. The units galvanically isolate the input, the output and the power supply.
The input signal may be 0-20 mA, 4-20 mA, 0-10 V, the intrinsically safe output signal also may be 0-20 mA, 4-20 mA, 0-10 V.
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.
