The DT1102 IP… galvanic isolators with passive current output are necessary in cases where signal sources with active (voltage, current) output must be connected to a signal processor with active input.
Active input signal processors are used to receive 4-20 mA two-wire (passive) transmitters, their input powers the transmitter connected to them. The passive current output of the DT1102 IP matches the input of this type of signal processor, solving the connection of active output signal sources.
The DT 1102 IP has three-way isolation, i.e. the input, output and power supply are galvanically isolated from each other. Continuous isolation voltage is 250 VAC
The input ranges are selectable with front panel switches:
- 0-20 mA / 4-20 mA / 0-10 V / 2-10 V
A 20 VDC / 24 mA transmitter power supply is available at the input for powering passive 4-20 mA two-wire transmitters.
The device has two inputs:
- current: 0 (4) mA – 20 mA*
- voltage: 0(2) V – 10 V*
* only one input can be used at the same time
The transmission characteristics are exceptionally good: non-linearity < 0.01%, temperature factor < 25 ppm / °C typically.
The LED indicators on the front panel provide information on the presence of power supply and possible error conditions.
The device can be ordered with two types of power supply:
- DT1102 IP: 24 V ± 10% DC,
- DT1102 IP PS: 230 V ± 10% AC/DC
The device has a 12.5 mm wide terminal box design and can be snapped onto a TS-35 rail.
