The pulse output of the N20K48 can be set for on/off control or time proportioning control. Time proportioning control is form of Pulse Width Modulation(PWM) but the pulse output is typically used for heating control applications. The output of the pulse is 5 Vdc maximum. / 20 mA and designed to drive a solid state relay(SSR). The controller will adjust the duty cycle according to the PID control algorithm( you can also set the output manually). The cycle period time is adjustable between 0.5 and 100 seconds which is suitable for heating control but may not be a good choice for other applications. Since your injectors have a 12V input and the voltage output of the pulse is 5V maximum, the pulse may not be not directly compatible with your injectors. You could use some form of amplifier or even an SSR between the pulse output and injector to resolved that issue. You would also have to determine if the cycle period of the pulse output is appropriate for your injectors.
