1. Brief Introduction
EM113016-04 is a single-phase multi-functional din rail energy meter with built-in relay which support RS485 communication, can realize remote reading data, remote control, automatic cut off; with good reliability, compact size, light weight, beautiful appearance, convenient installation, etc; which also comply with IEC standards.
2. Technical Parameter
3. Function Description
3.1 Metering Function
3.1.1Can measure active and reactive power, voltage, current, power, frequency, power factor, demand;
3.2 Communication Function
3.2.1Supports RS485 communication, support MODBUS, DLT645-1997, DLT645-2007, three protocols compatible, can read or write power data through RS485 communication and set data.
3.3 Display Function
3.3.1LCD screen display, data wheel display, but also by pressing the external button to page up and down. Display parameters can be set(settable parameters are: voltage, current, active power, reactive power, active power, reactive power, power factor, default parameter: active power, current, voltage, power factor. And the number of pages displayed on the LCD screen, the order of display, and the interval between pages can be set.)
3.4 Warning instructions
3.4.1 Under normal conditions, the alarm indicator is dim.
3.4.2 When overload level 1 alarm occurs, the alarm indicator is red and flashing, and the flashing state is 1 second on and off for 1 second.
3.4.3 When the overload level 2 alarm occurs, the alarm indicator is long-time red, and the relay will automatically disconnect after the overload lasts for N minutes (default 10 minutes), and the power supply will be cut off. After 5 minutes, the relay will be closed automatically. If the current is still greater than the level 2 alarm value for 5 minutes, the relay will be opened again. After 5 minutes, the relay will be automatically closed again. If the current is still greater than the level 2 alarm value for 5 minutes, the relay will be disconnected again; after M minutes (settable), the relay will be closed automatically or through communication/manually.
