Why Choose the WAGO 750-677/040-000 PWM Output Module?
The WAGO 750-677/040-000 is a rugged 4-channel pulse width modulation (PWM) output module designed for integration within the WAGO I/O System 750 XTR. It generates precisely adjustable PWM signals that allow automation controllers to regulate devices such as proportional valves, heating elements, lighting systems and motor drives.
Each of the four channels produces a configurable PWM signal operating at up to 20 kHz switching frequency with a 24 V DC output and up to 0.2 A load current. The outputs can be individually configured as high-side or low-side switching channels, providing flexibility when controlling industrial loads. :contentReference
