Often expensive solutions with sufficiently high temperature stability and vibration resistance are needed for process automation in harsh environments. However, in the case of simple control and regulation tasks with few inputs and outputs, economic solutions are called for, above all.
The fully encapsulated logic units WCU 501 and WCU 650 reliably monitor, control and regulate processes – even under extreme environmental conditions. The graphics programming allows flexible switching of the analog and digital inputs, as well as the power outputs.
Whether in apparatus and panel building, for autonomous automation tasks, as a monitoring system or for signal processing for superordinate controllers: the WCU logic units are small, intelligent, flexible, extremely robust and can be deployed especially cost-effectively.
The WCU 501 logic unit is used in the „Tower Installation“ system for wind power installations to inform service technicians with a flashing signal about failure of the external power supply.
Intelligent, flexible and robust
Complete encapsulation of the PCB makes the electronics insensitive to humidity. The range of application lies between −40 and +70 °C. The WCU logic unit withstands vibrations up to 5 g and shocks up to 10 g.
The WCU logic units have a large number of predefined function blocks – from the basic arithmetic operations through to timers. This makes them into intelligent automation tool.
Thanks to the encapsulated PCB, the electronics are extremely insensitive to humidity, temperature fluctuations, vibrations and shocks.
All WCU logic units have several analog and digital inputs, several power outputs and a PWM output. The WCU 650 communicates via a CAN bus interface to other bus users or superordinate controllers.
Simple, graphic programming
For programming, the WCU logic units are connected via USB cable to a standard PC. The free software is intuitive to operate.
We combine consultation, application competence and industry expertise and offer comprehensive solutions for wind energy applications from a single source.
