Electronic Timer Relay

Timing starts as soon as supply is connected to terminals A1 and A2. At the end of set time, OUT signal gets ON and internal relay status changes (internal contact of terminal 15 to 18 is made). As long as supply voltage is connected and has not dropped more than 40%, output remains unchanged. After de-energization, OUT signal gets OFF and internal relay reverts to its primary status and is ready for retiming (internal contact of terminal 15 to 16 is made). Attention: In the case of de-energization during timing, no change happens at output. After re-energization, timing starts from zero. Ability : Start measuring the time after connecting the supply voltage Select time from 5% to 100% suffering time

Three phase monitor relay

Three-Phase-Monitor Relay Model KRP101 (specific for 3-phase 3-wire networks) This relay is used in three-phase circuits (three wires) that are not functional null, for detecting the following errors and circuit breakdown: Phase loss or asymmetry in network voltage ( ASY.V 5 – 20 %) Phase sequence (P.S) Network voltage under 20% ( UV<300V ) Network voltage over 15% ( OV>440V ) Input power supply connection ( PWR ) It has 6 LEDs for displaying faults (red), output relay connection (green) ,input power supply connection (yellow) Ability to set the connection time after correction error (DELAY) between 0.5 and 30 seconds Three Phase Monitor Relay Model KRP102 (With Null, 4-wire networks) This relay is used in three-phase circuits (four wires) that are functional null, for detecting the following errors and circuit breakdown: Phase loss or asymmetry in network voltage ( ASY.V ) Phase sequence ( SEQU ) Network voltage under ( VOLT ) It has 4 LEDs for displaying faults (red), output relay connection (green) Ability to set the connection time after correction error (DELAY)

Over load monitor relay

Electrokaveh Three-phase analog control relay with three separate channels for conducting three-phase wire. Flow measurement from three-phase wires and output relay is controlled by adjusting the value on the device. If the flow is less than the current, connec t the relay, and if the flow of the current is greater than the set value after a time, the amount of delay setting is interrupted if the error persists. This can be done in two ways, automatically and manually, to reboot the device if an error is resolved. Just connected K1 terminal to K2 for automatic startup and connect the relay after it is cleared. The device is powered by 220 volts and connected to the A1 and A2 inputs of the device and the relay is connected immediately and terminals 15 to 18 are connected.
