OCM-01 Over Current Protection Relay (0.5A - 5A)
OCM-01 Over Current Monitoring Device protects motors and the system they are connected.
If the measured current of a motor or a system less than adjusted over-current value, "relay indicator" turns on. When the measured current exceeds adjusted over-current value, relay indicator turns off and relay contact would be open circuit after delay time.
Over-Current Adjustment : Over current value could be set between 0,5 and 5A. It is the desired over current value for protection of a motor or a system. The hysteresis value is %3.
Start Delay Time Adjustment T(s) : Start delay time could be set between 1 and 6 seconds. After the motors start to run, they draw high current within a short time and the measured current value could exceed the adjusted over current value. To avoid the operation failure during this time, the device would not energize the relay. After start delay time the current would be measured.
Delay Time Adjustment T(d) : Delay time could be set between 0,5 and 3 seconds. When the measured current exceeds adjusted over current value, relay contact would be open circuit after delay time and motor would be deenergized. If the measured current value falls below the limit during this time, delay time would be reset.
ON (Power) : Turns on, if the device is powered.
OUT (Relay) : Turns on, if the relay contact is short circuit.
I>Iset : When the measured current exceeds adjusted over-current value, LED flashes during delay time. At the end of the delay time it turns on continuously.
