ICPDAS I-8088W
8-channel PWM Output And 8-Channel isolated DI Module
● Automatic generation of PWM outputs by hardware, without software intervention.
● 10Hz ~ 500kHz (non-continuous) 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.
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. I-8088W has 8 PWM output channels and 8 digital inputs. It can be used to develop powerful and cost effective analog control system.
With different communication interface, the I/O modules can be classified to high communication speed (Parallel bus) 8K series modules and low communication speed (serial interface) 87K series modules.
| There are two types of I/O modules, Parallel and Serial. The parallel modules (I-8 Series) are high-speed modules and support MCU (Main Control Unit) only. | |

High Profile VS Low Profile
With different form factor, I/O modules can be classified to high profile and low profile. Basically, high profile and low profile modules that with same item number also have same I/O channel number.
For example: I-8054 and I-8054W both has 8 DI and 8 DO.
Except I/O channel number, other specifications could be different. You have to double check whether the specifications suit your application.
For example: For I-8054W, its DI logic high level is +10 ~ +50V. But for I-8054, it is +3.5 ~ +30V
