ISOLATED analog signal CONVERTER voltage to current: 0 to bipolar 100mV into 0 to bipolar 20mA

Voltage to current converter, isolated.

Conversion of low bipolar voltage into proportional bipolar current. Multiple protections, easy set-up, economical.

This mini-module with triple isolation (2000V) proportionally converts “0 to ±100mV” applied on its input into “0 to ±20mA”, rapidly and precisely.

Description

Input: 0 to ±100mV ; impedance > 100 kΩ

Output: 0 to ±20mA, on load ≤ 500 Ω

Accuracy: better than 0.2%

Regulation: < 5.10-4, with load varying from 0 to 500 Ω

Ripple: < 300 μA

Response time: < 2.5 ms (can be increased upon request)

Isolation: triple, with input/output, input/supply and output/supply: 2 kV

Power supply voltage:

  • standard, 24V DC ± 10% / < 45 mA
  • optional power supply:
    • 24V~ or 110V~ or 230V~ ±10% / 48Hz to 400Hz
    • 5V or 12V or 48V DC

Possible load: ≤ 500 Ω

Protections:

  • against inverted connections on the input and power supply
  • against accidental overvoltage on input: ±5V
  • against overloads and short-circuits
  • against bipolar overvoltages on the output
  • isolations 2000V
  • 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 Ø 1mm (CI)

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