Wago 750-677/040-000 4 pulse width outputs

This module outputs separately adjustable PWM signals at four channels. The channels can be individually configured as LSS (low-side switching) or HSS (high-side switching) and are short-circuit protected. The PWM signals are each 16 bits wide. The module supports five operating modes. In both “PWM DC” and “PWM Frq” operating modes, all four channels may be used independently. The bridge mode can also be activated if the same operating mode is set on each channel pair (1 and 2 or 3 and 4). Both channels work synchronously and can be connected in parallel. In the other three complex operating modes, two channels functionally correlate with each other. The first channel outputs the PWM signal and the second channel a static signal (“0” or “1”). Refer to the manual (“Operating Modes” section) for all setting options and the bit signification in the process image. The “PWM DC” operating mode is set by default. The device is ideal for operation in extreme environments thanks to: • An extended temperature range • Greater immunity to impulse voltages and electromagnetic interference • Higher vibration and shock resistance
