ISOLATED analog signal CONVERTER voltage-current: 0 to 500mV into 0 to 20mA proportionally

This mini isolated converter with triple isolation (3000V~) proportionally converts “0 to 500mV” input signals into “0 to 20 mA”.

Advantages: triple isolation, multiple protections, easy set-up, economical.

Description

Input: 0 to 500mV; iin max = 500µA

Output: 0 to 20mA, on load ≤ 500 Ω

Accuracy: better than 0.2%

Regulation: < 10-4, with load varying from 0 to 500 Ω

Ripple: < 300 μA

Response time: < 2 ms (can be increased upon request)

Isolation: triple, with input/output, input/supply and output/supply: 3kV~

Power supply voltage:

  • standard, 24V DC ± 5% / ≤ 28mA / 500Ω loaded and ≤ 15mA unloaded
  • optional power supply:
    • 24V~ or 110V~ or 230V~ ±10% / 48Hz to 400Hz
    • 5V or 12V or 48V DC

Possible load: 0 to maximum 500 Ω

Protections:

  • against inverted connections on the input and power supply
  • against accidental overvoltage on input: 2V
  • against overloads and short-circuits
  • against bipolar overvoltages on the output
  • isolations 3000V~
  • against vibrations, and tropicalisation: with moulding
  • sealing iP67, except connections
  • elimination of the faulty-contact risk (no DIL switch)
  • negligible temperature rise (high performance conversion)
  • 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 with external connector and 2 M3 screws (P)
  • mounting on printed circuit, connecting pins ∅ 1mm (CI)

Optional: all-aluminum case, 89 x 35 x thickness 16 or 30mm, with three mounting possibilities (M)
