“With delay to energise on a rising current”. The output relay delays to energise for up to 10 secs when the monitored current rises above the set level as selected by the front potentiometer. It will de-energise when the current falls below the set level less a fixed hysteresis of 1% against the set level. De-energisation will also occur if the auxiliary supply is lost.

The MOD-I can be used to monitor a 3 phase motor by passing one phase into terminal A1 and out on the relevant I.. terminal to the load. The panel Neutral needs to be connected to terminal A2 even if the load does not have a Neutral connection. All terminal details and information along with the CE mark is clearly marked on the sides of the housing.

Single range versions of the above product are available product type YRI-41.
