Macromatic's PMD Series, three-phase monitor relay for DIN-rail mounting

Macromatic Industrial Controls announced today its redesign of the PMD Series, a Three-Phase Monitor Relay for DIN-rail mounting. The PMD Series protects motors from premature failure due to phase loss, phase reversal, undervoltage, overvoltage and phase unbalance conditions along with rapid cycling.

PMD Series Three-Phase Monitor Relay

Macromatic redesigned the PMD Series Three-Phase Monitor Relay to offer a variety of options while keeping it easy to use:

  • Universal voltage range of 190-500V-greater range that covers more global applications (a separate 480-600V version is also available)
  • Full status LED retains fault indication and continues monitoring all voltages even with a phase loss
  • True RMS voltage measurement ensures accurate sensing across more applications
  • Bright LED provides clear indication and simplified troubleshooting
  • Manual Reset works with external switch allows unit to be easily reset from outside the enclosure
  • DPDT output contacts
  • Mounts on 35mm DIN-rail
  • Meets IEC/DIN enclosure design standards
