Main features and functions

Main features

This section describes the main features fro Model KM1.
• Models providing the following functions are lined up and are selectable according to intended
end-usage.
Power measurement
Detection of over or under current
Temperature measurement
Pulse input count
ON time of pulse input
CO emissions/conversion to electric power charge
2
3-STATE function (power, current, and voltage)
Reverse phase detection
Power measurements of two different systems insulated each other can be made using a unit.
The installed logging function allows the user to select eight cycles (5 min, 10 min, 30 min, 1
hour, 2 hours, 6 hours, 12 hours, 24 hours) available for saving data.
Two types of communication protocol, CompoWay/F (*1) and Modbus (RTU) (*2), can be
supported by one unit.
Conforms to the safety standard (EN/IEC).
[Connection of multiple units (PMU1A (electric power)/PMU2A (power two-system) + EMU8A
(pulse/temperature))]
・ According to the event input of EMU8A (pulse/temperature), the total power consumption
measured with PMU1A (electric power) and PMU2A (power two-system) can be classified to the
three states: HIGH state, MIDDLE state, and LOW state. (3-STATE function)
[Connection with Model KE1]
Connection with Model KE1-CTD8E can expand current CT, allowing the user to make
measurements at 36 points maximum.
After this, this manual also describes the expansion function of current CT when this product is
connected to KE1-CTD8E (CT expansion unit).
For Model KE1-CTD8E, refer to "Model KE1 User's Manual" (SGTE-717).
*1 CompoWay/F is a unified communication procedure within Omron's generic serial communication.
It has commands conforming to the time-proven FINS in the unified frame format and Omron's
programmable controller, making easy the communication between the personal computer and the
components.
*2 Communication control system conforming to RTU Mode of Modbus Protocol. Modbus is a
registered trademark of Schneider Electric.
