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.
• Extension module: R7LWTU-EA8[1]
Specify a code from below for [1].
(e.g. R7LWTU-EA8/Q)
Current sensors are easy to install in existing systems. Wide
input range of 5 to 600 A is availabe.
• Specify the specification for option code /Q
(e.g. /C01)
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.

CONFIGURATION
2: Single phase / 2-wire and 3-wire,
RELATED PRODUCTS
• PC configurator software (model: PMCFG)
3-phase / 3-wire and 4-wire
• XIF File (Device Interface File)
[1] NO. OF SYSTEMS
1: 1 system, Di / Pi x 4 (internal power 5 V)
(no connection with extension module)
2: 2 systems
XIF file is used to define a LonWorks device when
programmed on LonMaker.
The XIF files and Software are downloadable at M-System’s
web site.
To connect the module to a PC a dedicated cable is required
(refer to M-System's 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.
