FUNCTIONS & FEATURES

The R7LWTU is a Multi Power Module for LonWorks.
The R7LWTU 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.
A ‘basic’ module can be attached with an ‘extension’ module (except R7LWTU-211-AD4)because of this, it is able to use it as 2-circuit power and 8 discrete inputs module.

RELATED PRODUCTS

• PC configurator software (model: PMCFG)
• XIF File (Device Interface File)
XIF file is used to define a LonWorks device when programmed on LonMaker.
The XIF files and Software are downloadable at our web site.
To connect the module to a PC a dedicated cable is required (refer to our web site or instruction manual).
• 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.
