Zener Diode Barrier MTL7787+

The MTL7787+ barrier contains two stages of pulse-tested Zener or forward-connected diodes and an ‘infallible’ terminating resistor. In the event of an electrical fault in the safe area, the diodes limit the voltage that can reach the hazardous area and the resistor limits the current. A fuse protects the diodes, and the two stages of voltage limitation ensure continued safety if either stage should fail. No active output-current limiting circuits are employed. The MTL7787+ is certified ‘ia’ for all zones and ‘IIC’ for all explosive atmospheres.

A Zener-Diode Barrier which is intrinsically safe and zone-powered, for use in conventional fire detection systems for protection within hazardous areas. Certified ‘ia’ for all zones and ‘IIC’ for all explosive atmospheres.

Features:

  • Easy instalation on DIN rail
  • Certifiet Ia and IIc, for all explosive places
  • Removable colour-coded terminals for easy connection, accommodate conductors up to 2.5 mm2
  • Supports up to two zones of I.S. products
  • Input circuitry protected against reverse polarity
  • Can use with the IFD-E(IS) industrial IR3 flame detector
  • Removeable Colour Coded Terminals For Easy Connection
