Long-life, bright, and large 7-segment LED indicator This LED indicator has longer service life compared to LCD, and indicated values can be read clearly both in bright and dark places. The 6-digit-display helps you recognize at a glance which item is being set. Lenses which enable clear and easy view from any direction were adopted. Operation indicator lamps can be seen from above, below, left and right. Compatible with old-type models Protection, control and monitoring of motors are managed by a PC. Also energy-saving and failure analysis are supported. As this model is compatible with old-type motor multi-relays, it is possible to renew them and enhance their monitoring functions. The unit can be connected to a PC using a commercially available USB-cable. Security function Switch operation can be locked by setting the lock-function. The lock will be released by inserting the unlock key. *Unlock key (optional) Type CCR-RKEY Easily understandable trip indicator When a trip occurs, the orange lamp will light. The 7- segment LED will indicate the cause of the failure and blink. In addition to power and power consumption, power factor is also measured. It is possible to measure power, power consumption and power factor. These measurements serve for energy-saving. *Pulse output (insulated) for power consumption can be output as standard. Protection against corrosive gases Switch contacts and connector contacts on the circuit board are gold-plated and thus resistant to corrosive gases.
