    The SRW01 is a low-voltage electric motor management system with state-of-the-art technology and network communication capabilities. Additionally, its modular concept allows to be used in various applications.

    The SRW01 supports the following communication networks protocols: DeviceNet, Modbus-RTU, and ProfiBus-DP. The communication modules can be easily exchanged due to plug-and-play capabilities. A HMI also can be used for quick system monitoring and relay parameterization. Additionally, the SRW01 provides a USB port for relay monitoring and programming through PC when using WLP software. The SRW01 includes a thermal memory circuit in order to maintain a motor thermal image, even if power
