M-7088 has 8 PWM output channels and 8 counter inputs. It can be used to
develop powerful and cost effective analog control system. PWM (Pulse width
modulation) is a powerful technique for controlling analog circuits. It uses
digital outputs to generate a waveform with variant duty cycle and frequency to
control analog circuits. It can be used to Controlling the position/speed of
motors, Dimming the brightness of lamps, Controlling the speed of fans… etc.
Features
- Automatic generation of PWM outputs by hardware, without software
intervention.
- 10Hz ~ 500KHz PWM output frequency with 0.1%~99.9% duty cycle
- Software and hardware trigger mode for PWM output
- Individual and synchronous PWM output
- Using software trigger mode, you can set configuration for all PWM channels then
trigger them one by one or all of them at the same time.
- Burst mode PWM operation for standby
- DI channel can be configured as simple digital input channel or hardware trigger
source of the PWM output.
