We successfully developed AC drives as SY6600 series, SY7000 series, SY8000 Series and SY8600 series, soft starter as SJR2-2000 series economical type, SJR2-5000 intelligent type, SJR2-3000 built-in bypass type 3phase motor starter.
Product Description
“SJR2-3000” series online micro-power consumption 3 phase motor starter of Shanghai SANYU. The company has made further technical improvement in both the software and the structure of the 3 phase motor starter according to the market demand. With inbuilt bypass contactor the soft starter provides complete motor protection functions including start control, running and overloading, phase failure, three-phase unbalance, over-voltage, under-voltage protection and so on with no need to further install bypass contactor and thermal relay, therefore, as another great achievement in the intelligentization of motor protection and networked technology application, it simplifies the circuit, reduces the volume, cuts the cost, makes installation and using more convenient.

Function description
Connection point output
01, 02
Power input
01, 02 are AC220V power input to the control panel
03, 04
Running output (delay)
03, 04 are programmable relay output, the delay time is set by the code F4 while the output function time is set by code FE.
05, 06
Fault output
005, 06 are fault relay output, they will be on when there’s fault with the soft starter or the power is cut off and be off when the power is on. (capacity of the connection point AC250V/3A)
Connection point input
07
Instantaneous stop input
The motor will stop immediately when 07 and 10 are disconnected (or be tandemly connected to the normally closed point of the thermal relay)
08
Soft stop input
The motor will slow down for soft stop when 08 and 10 are disconnected (or automatically stop).
09
Start input
The motor will start for running when 09 and 10 are connected.
10
Common terminal
Common terminal for signal input of the connection points
Analog output
11, 12
Analog output
11 and 12 are 4~20Ma DC analog output which are used to monitor the current of the motor in real time. The maximum value 20mA indicates the current of the motor is four times of the nominal current of the soft starter.4~20Ma DC meter can be connected for observation. Maximum load resistance of this output is 300Ω.
Communication
DB
RS485communication input/output
Input and output signal terminal of RS485 communication, can be used to connect several soft starters.
