Control Unit ELC500

The ELC500 Control Unit enables program-less Ethernet data logging, demand monitoring and control at short intervals of five seconds, and remote equipment monitoring using a Web server. This product allows the incorporation of IoT in your factories and equipment to help optimize energy use and improve productivity.

Notes :
1) Settings must be made using Configurator EL500.
2) Web content must be produced using Control Web Creator.

Notes :

Demand monitoring at intervals of several seconds allows prompt response to sudden load fluctuations

Monitoring intervals and control patterns to meet the demand monitoring needs of users

Constant-cycle demand
Demand time span is compatible with constant-cycle demand periods of 15 / 30 / 60 minutes.

IEC demand[Compliance with IEC 61557-12 standard]
Demand monitoring complies with the IEC 61557-12 international standard commonly used for energy-saving measures.

IEC demand (Sliding block interval and Fixed block interval)
Users set the time span for demand calculation to an arbitrary value between 1 to 60 minutes (in increments of one minute). The average power demand within the set span is calculated at the end of the span. [The demand values of active, reactive, apparent, active (export), and reactive (export) power are calculated.]

Sliding block interval method Sliding block interval method The next time span starts "n" minutes later. (Value "n" is arbitrarily set by users.)

Fixed block interval method The next time span starts after completion of the current span.

■Three types of control patterns

Alarm-linked control Controls loads in three steps according to conductions such as demand values to achieve peak-cut.

Cyclic control Controls a group of loads in a rotation manner to reduce overall power consumption.

Startup control Delays the startup timing to reduce inrush power and achieve peak-cut.

Collection and storage of operation data of existing equipment using add-on device

Settings must be made using Configurator EL500 (compatible units: Modbus TCP / RTU and MEWTOCOL units).
SD memory card (sold separately) is required for data storage.

PLC's communication program is used for serial communication and storage of equipment operation status data.

There is no need for a program for serial communication and storage of equipment operation status data.

■ Reduces engineering man-hours ■ Improves maintainability ■ Allows easy change of layout

Extension function for logging of I/O signals, analog data and temperature data

To use the extension function, it is necessary to create a program using Control FPWIN Pro7.

There is no means to obtain equipment operation status information through communication function.

FP7 Expansion Unit enables acquisition of equipment I/O signals, analog signals and temperature information.

Note: To use the extension function, it is necessary to create a program using Control FPWIN Pro7.

■Connectable units

Realizes demand monitoring in large plants

There are certain restrictions such as the maximum number of connectable units.

For use in small stores or for partial demand monitoring

Our previous product featured a small number of control points, and its applications were limited to use in small stores or monitoring of partial demand in factories.

Small- / medium-size factories and large plants

By sharing receivingpoint demand information through the network, entire factory loads can be optimally controlled.

Use of the program function enables collection of data from other manufacturers' units that use different protocols

To use the program function, it is necessary to create a program using Control FPWIN Pro7.

Data cannot be obtained from other manufacturers’ power meters, so receivingpoint data cannot be acquired. Therefore, demand monitoring / control is not possible.

Data can be obtained from other manufacturers’ power meters, so demand monitoring / control is possible.
