Isolated and SELF-POWERED converter, current-voltage: 4 to 20mA into isolated 0 to 10V

Current-voltage converter, self-powered, no noise interference, isolated – 4 to 20mA into 0 to 10V 

This self-powered current-voltage converter is fully powered on the input current loop and drops less than 3.4V.

Not generating any noise interference, this “passive” quadripole converts, isolates and outputs within 0 to 10V analog signals from 4 to 20mA applied to its input.

Description

Input:

  • applied signal: 4 to 20 mA (accidental maximum: 80 mA)
  • ΔV between C and D in the current loop: < 3.4V

Output:

  • output signal: 0 to 10V
  • load: ≥ 220 kΩ

Full-scale accuracy: better than 0.2%

Response time:

  • regular: 20 ms
  • upon request: your choice from 1 ms to 10 seconds

Isolation: 2500 V~

Consumption:  only 4 to 20mA of the input current loop

Protections:

  • against reversal of connections on the input
  • against accidental overvoltage on input: up to 80 mA
  • against overloads and short-circuits
  • isolation: ≥ 5000 V~
  • increased reliability because of no external power supply
  • against vibrations; tropicalisation with moulding
  • sealing iP67, except connections
  • elimination of the faulty-contact risk (no DIL switch)
  • negligible temperature rise (high performance conversion)
  • total absence of noise interference
  • electromagnetic compatibility CEM 89 / 336 / CE

Temperatures:

  • coefficient: < 2.10-4 / °C
  • operation: -20°C to +60°C
  • storage: – 40°C to + 90°C

Three modules:

  • DIN rail mounting (RD)
  • wall mounting
  • mounting on printed circuit

Upon request:

  • Two channels completely isolated in a box for DIN rail (66 x 53 x 12.5 mm or 50.8 x 50.8 x 11 mm).
  • Both inputs can be connected in series.
