Product description
The DT1102 (PS) Switch Selectable Input-Output Galvanic Isolator provides signal transmission and conversion between DC current or DC voltage signal source and signal processing units.
The instruments feature complete 3-way isolation: the input, the output and the power supply are isolated from each other.
Continuous isolation voltage is 250 VACeff, between the input, the output and the power supply.
The instrument provides 20 VDC / 24 mA on the input for supplying passive two wire transmitters.
The DT1102 is particularly advantageous in industrial plants where different signal levels are in use.
The input/output ranges are selectable with front panel switches:

• 0-20 mA / 4-20 mA / 0-10 V / 2-10 V input
• 0-20 mA / 4-20 mA / 0-10 V / 2-10 V output

The instruments has two inputs:

• current: 0 (4) mA – 20 mA*
• voltage: 0 (2 ) V – 10 V*

The instruments has two outputs:

• current: 0 (4) mA – 20 mA*
• voltage: 0 (2) V – 10 V*

* it may be use only one input and one output at a time.
There are two power supply version: DT1102: 24 V ± 10% DC, DT1102 PS: 230 V ± 10% AC/DC.
The transmission parameters are outstandingly good: the non-linearity is < 0.01%, and the temperature coefficient is < 25 ppm / °C TYP.
Front panel LED’s indicate the power on state and the error states (input / output overrange, internal errors, etc.).
