New Temperature Converters for Railway Vehicles

We are presenting new temperature converters – the KSTID and KSTUD converters designed to convert resistance signal to the unified signal of 4 to 20 mA (KSTID) or 0 to 10 V (KSTUD).

Products for this segment must meet specific properties defined in the so-called railway standards (EN 50 155, EN 61 373, EN 50 121-3-2, and EN 45 545). They include especially resistance to vibration, electrical safety, they have to meet fire standards, and electronic components have to meet the conditions for electromagnetic compatibility (EMC).

The KSTID and KSTUD converters have successfully passed:

• Shock and vibration test, category 1, class B according to the EN 61 373 standard
• Electromagnetic compatibility test according to the EN 50 121-3-2 standard
• Insulation test according to the EN 50 155 standard
• PCB and a plastic box are made of the material that meets requirements of the fire standard no. EN 45 545-2

Input signal could be Pt 100 or Pt 1000. Output signal is 4 to 20 mA or 0 to 10 V. Standard temperature ranges could be:

• -30 to 60 °C
• 0 to 35 °C
• 0 to 100 °C
• 0 to 150 °C
• 0 to 200 °C; others as requested
