Remote Transmitter Protector


  • Three stage protection and fine over-voltage protection helps ensure lowest residual surge voltage reaches sensitive equipment
  • Flexible installation allows enclosure to be installed “dead ended”, “T” configured or in-line
  • Optimized for protection of 2-wire industrial 4-20mA loops and suitable for exposed locations
  • Supports line currents up to 145mA and protects 24VDC powered equipment
