FUNCTIONS & FEATURES

The R7CWTU is a Multi Power Monitoring Module for CC-Link.
The R7CWTU uses clamp-on current sensors, there is no need of current transformers.
Current sensors are easy to install in existing systems. Wide input range of 5 to 600 A is availabe.
All measured values, counter values, display mode, setting data are stored in the non-volatile memory when power is off.

RELATED PRODUCTS

• PC configurator software (model: PMCFG)
Downloadable at our web site.
A dedicated cable is required to connect the module to the PC.  Please refer to the internet software download site or the users manual for the PC configurator for applicable cable types.
• Clamp-on current sensor (model: CLSE)
The clamp-on current sensors, not included in this product package, must be ordered separately. Required number depends upon the system configuration.
