LTMR

  • Over Temperature detection
  • Used in conjunction with PTC thermistors to DIN 44081
  • Auto-resetting
  • Isolated Auxiliary Supply
  • SPDT Relay output
  • 17.5mm wide, DIN Rail mount

The product is used in conjunction with an external PTC thermistor which are typically embedded in motors. It will monitor the resistance of the thermistor and if this increases above the fixed threshold (due to an increase in measured temperature), the relay will de-energise. The resistance must decrease below the “release” threshold before the relay re-energises again.

  • Monitoring function: Over temperature
  • Operate resistance: 3100 ohms
  • Release resistance: 1650 ohms
  • Aux. supply voltage: 100 – 230VAC/DC (Order Code: 99-3201)
  • Output: SPDT 5A @ 250V (AC1)
  • Dimensions (mm): W:17.5 x H:89 x D:66.5
