EM500 Series Motor-protective Device

Smart Motor-protective Device EM500 series inteliligent motor control,designed by shanghai SAILFAR Electric Technology Co.,Ltd,is used for the contactor(AC50HZ-60HZ,690V,upto 820A) to protection,measurement,display,diagnosis,electrical control, and communication of low-voltage motors.as it appears such faults as overheat,overload,currentjam,undercurrent, phase imbalance,ground fault,residual current,under voltage,over voltage etc. 

Applition:
In the fields of power,steel making,petrochemical,cement,gas industry and papermaking,EM500 series motor controller is widely used to provide reliable and effcient  control for protection of low-voltage motors.

Function:
1.Easy setting and powerful diagnosis
With user-friendly HMI interface,EM500 series motor-protective Device can
easily fullfill these function that display parameters,inquire faults,read
And set functional data and systermatical parameters,self-test.ect.
2.All-round protection integrated
Built-in all-round protection can easily push on/off all protections.
3.Over-load protection
Over-load protection is accessible to multiple release grades,(IEC standa-
rds) and meets the requirements of heavy-load re-starter.
4.Mulitiple fieldbus and industrial Ethernet supported
standard RS-232,RS-485 and USB communication interface,multiple bus
protocols(optional):MODBUS,CAN,Profibus-DP,Device NET field bus
protocol and industrial Ethernet.
5.9DI,4DO integrated in the basic unit
Flexible programmable I/O,9DI and 4DO inside,can meet most of applications
without any other expanded modules.
6.High-resolution wide-temperature LCD display
High-resolution wide-temperature LCD display can be used for operation
status monitoring and parameter setting,even the temperature is as low as
-20 centigrade.
7.High Clarity all-round Measurements
Electrical values such as current,voltage,power consumption,power factor,
electrical energy and frequency,etc,can be measured with high accuracy.
8.Convenient Maintenance and Management
Fault and alarm messages,operation status indication,operation records
and stastistics can be accessible for easy maintence and managment of
motors.
9.Flexible installation
It can be installed directly in low-valtage and motor control switchgears
such as MODAN6000,MODAQO-X,MODAQO-M,MCC3000 and other 1/4-module types of
switchgears.
