2.3 ABOUT THE SRW 01
The SRW 01 is a low voltage electric motor management system that presents cutting edge technology and has
network communication capabilities. For being modular, its functionalities can be extended, making it a versatile
product, and prepared for several applications.
The SRW 01 has a modular design that allows the expansion of the relay functionalities. The Control Unit (UC)
can be mounted together with the Current Measurement Unit (UMC), forming a single unit, or separated (up to 2
meters [6.56 ft]) from it.
By using the Expansion Digital Unit (EDU), it is possible to increase the number of digital inputs and outputs in the
Control Unit (SRW01-UC), in a total of 12 digital inputs and 8 outputs.
It is possible to use a Current/Voltage Measurement Unit (UMCT) in place of a Current Measurement Unit (UMC).
Besides measuring the motor currents (like the UMC), it is possible to monitor the voltages up to 690 V, phase
sequence, power factor (cos
ϕ
) and all motor powers.
In order to exchange information via Ethernet communication network, the SRW 01 features two RJ45 ports with
integral switch, which enables the execution of different network topologies of the fieldbus technique.
The SRW 01 has an USB port that makes the parameterization, monitoring and programming of the relay easier
by using a PC with the WLP software. Because of the thermal memory, the relay is able to keep the motor thermal
image even when it is not energized.
