Current monitoring relay MRI25T

This range of current monitoring relays are used for the control of AC current signal in various industrial and domestic applications. The measuring part of the instrument is galvanic separated from the current connection terminals. The monitoring relays MRI range have one double-throw output contact up to 16 A.

  • measuring range 2.5 ... 25 A
  • output relay contact 16 A
  • universal supply input 89 ... 264 VAC
  • small dimensions 1-module on DIN rail
  • optical status LED signalization
MRI25T

Function

If the set current level is exceeded, output relay will make connection. If the measured current level goes under the set level minus fix hysteresis 10%, output relay will disconnect. Hysteresis reduces relay bouncing at threshold limit of current values. Position OFF disables current measurement, output is closed and yellow LED is off. Contact no. 16 – 15 is closed.
