Area of application
The DT1315 xx xx Intrinsically Safe Output Isolator 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 potentially explosive area.
The instruments 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.
Operating principle
The instruments are powered from a 19-29 VDC supply
trough a dual output high frequency DC-DC converter. One
output supplies power for the input (safe) side, the other
supplies power for the output (Ex) side. The DC isolation
and intrinsically-safe segregation are provided by high
isolation optocoupler. The DC signal transmission based on
a high precision pulse modulation-demodulation principle.
Power supply
The instrument works from a 19-29 VDC supply voltage.
The power consumption is 1.6W.
