Description

ST500Ex-10-5, Intrinsically Safe Universal Isolating Signal Converter, 24VAC/DC

Properties:
The ST500Ex isolating signal converters can be used to isolate and convert field signals 0/4...20mA or 0/2...10VDC out of the intrinsically area.
Isolating signal converter for application in zone 0 or zone 20 (constant explosion risk) with integrated transmitter supply. It allows the direct connection of active 2-wire sensors (4 ... 20 mA) and 3-wire sensors in the Ex-area.
The ST500Ex provides a fully floating isolated transmitter supply.

  • Input intrinsically safe ATEX II (1) G [Ex ia] IIC, II (1) D [Ex iaD]
  • 2 power-supply-designs with wide range of allowed supply voltage:
  • 10 ... 30 V DC / AC oder 85 ... 253 V AC
  • Electrically isolated: between input / output / supply voltage
  • 22.5 mm standard case for rail mounting TS35
  • Universal inputs/outputs for (0)4 ... 20 mA and 0(2) ... 10 V
