WAGO Kontakttechnik
The Pro 2 line of power-supply units (PSU; photo), with units ranging from 120 to 960 W, can connect to various gateways via a snap-on communication module (currently, IO-Link; Ethernet-based protocols such as Modbus TCP, Ethernet IP, ProfiNet in the future). This selection of standardized protocols ensures convenient and reliable integration into the respective infrastructure. Data from the Pro 2 PSU can be saved and analyzed for energy optimization; the central PLC can switch off distributed PSUs in parts of the system via a hardware signal or bus command in order to activate standby mode to save energy — and with the unit’s monitoring functions, provide information about current power supply or connected load data, and signal errors for seamless application monitoring. This status information, which can be retrieved by the controller at any time, eliminates the need to check the output voltage manually and allows on-time maintenance of the power supply and all connected loads. — WAGO Kontakttechnik GmbH & Co.
