a pulse-width modulated (PWM) output. Its rugged design is
optimized for driving electromechanical devices such as
valves, solenoids, relays, actuators, and positioners. It is also
ideal for driving thermal devices such as heaters, coolers,
and lamps. PWM operation conserves power and reduces
heat rise, resulting in higher reliability. In addition, adjustable
PWM allows fine control of the power delivered to the load.
Time from dc-to-PWM output and oscillator frequency are
externally adjustable. …
