2.0 Description and Documentation
Energy Monitoring Modules PWRM10-01 and PWRM20-01 are IoT, universal, high accuracy,
compact, self-powered, electrical energy measurement devices that interface to three-phase and
single-phase systems. The modules are specifically designed for heavy-duty industrial and
commercial installations and retrofit applications, providing a wide range of highly accurate power
and energy measurements over an operating temperature range of -40°C to +85°C.
The DIN rail mounted enclosures have pluggable terminal blocks for connecting to phase voltages
and phase currents which simplifies setup and maintenance. Both modules have a small form factor
which occupies less space in control cabinets than other measurement solutions. The PWRM10-01
module interfaces to phase voltages of 85 –265VAC, 50/60Hz and is self-powered from any of the
three phases. For higher voltage systems, the PWRM20-01 module interfaces to phase voltages of
85 –525VAC, 50/60Hz and is self-powered from any of the three phases. Both modules can interface
to higher phase voltages with the use of voltage transformers and scaling configured in the module.
Power consumption is low and does not affect measured power and energy.
Phase current inputs have an industry standard range of 0.333VAC full scale. The modules are
configurable to use an external shunt, current transformer, or Rogowski Coil to measure phase
currents directly or non-contact.
The PWRM10-01 and PWRM20-01 modules measure and report a wide range of electrical energy
parameters which include, but are not limited to:
•RMS Voltages and Currents
•Phase Angles
•Line Periods
•Instantaneous Total Active Power
•Instantaneous Total Apparent Power
•Fundamental Active Power
•Power Factors
•Total Active Energy
•Fundamental Active Energy
•Fundamental Reactive Energy
•Reactive Energy
•Harmonics
•Power Quality –Configurable Events Monitor and Post Notifications for:
▪Over-Voltage
▪Over-Current
▪Sag
Real-time data from the module is accessed via an Ethernet port using the HTTP API or a standard
web browser on a host computer, smart phone, or tablet. Data logging is user configurable and once
parameters and ranges are selected, the data is automatically downloaded and stored.
With the ease of use and many features of the PWRM10-01 and PWRM20-01 modules, measuring
power quality, monitoring energy consumption, determining machine health, and other powerful data
analyses become simple operations.
PWRM module literature and software is available for download from the
PWRM Software & User Manual Download Center. This includes, but is not limited to:

4.0 Installing the Module
Each PWRM10-01 and PWRM20-01 module is shipped in electro-static discharge (ESD) protective
packaging. Use appropriate ESD protection measures while unpacking. If physical damage is noted,
file a claim with the shipping carrier and contact the factory.
4.1 Mounting on a DIN Rail
ATTENTION
Read, understand, and follow all instructions in this manual and MA1068 PWRM10 & PWRM20-01
Hardware User Manual including all warnings, cautions, and precautions before installing and using
the product.
󰈼CAUTION –RISK OF ELECTRICAL SHOCK
When installing and operating the PWRM10-01 and PWRM20-01 modules, there is a potential shock
hazard from dangerous high voltage. Ensure systems are de-energized before installing the product
or removing the terminal blocks.
The PWRM10-01 and PWRM20-01 modules mount on 35mm DIN rails that are elevated or flush on
panels. They require no tools or hardware for insertion into a system and only a simple flat blade
screwdriver for removal.
To install a module:
1. Orient the module with the metal latch down and the Ethernet jack away from the DIN rail
2. Align the module DIN rail capture with the top edge of the rail
3. Slide the module down until the module engages the rail
4. Rotate the module and snap in place

Figure 2: PWRM20-01 Installation and Removal from a DIN Rail
To remove a module:
5. Insert a flat blade screwdriver into the slot in the metal clip
6. Lift the screwdriver to pull back the clip and release the module from the rail
4.2 Wiring to Phase Voltages and Phase Currents
The PWRM10-01 and PWRM20-01 modules have pluggable terminal blocks to connect to phase
voltages and phase currents. This allows modules to be easily added to or removed from a system.
The modules are powered by the phase voltages and an external power supply is not required.
󰈼DANGER –HAZARDOUS VOLTAGES
These wiring instructions are for use by qualified personnel only.
Only licensed electricians or qualified personnel should install and maintain the modules and wiring.
REFER TO MA1068 PWRM10-01 & PWRM20-01 Hardware User Manual FOR DETAILS ON
WIRING TO PHASE VOLTAGE AND FOR SENSORS AND WIRING TO PHASE CURRENTS.
PWRM10-01 and PWRM20-01 modules interface to phase currents with burden resistors, current
transformers, or Rogowski Coils with 0.333VAC output at rated current. This low voltage interface is
on the module top terminal blocks.
PWRM10-01 and PWRM20-01 modules interface to phase voltages using the bottom terminal blocks.
WARNING!
Mains voltages of 85VAC to 525VAC can be lethal!
