Expert FAQs
- How are the output channels grouped?
- The eight outputs divide into two groups of four channels. Each group shares a common connection point.
- What happens at higher temperatures?
- The output current reduces to 0.5A per point at 60°C. This protects the module from overheating.
- Can it handle motor startup surges?
- Yes, each point handles 10A surge current for 25ms. This covers most motor starting loads.
- What is the response speed?
- It turns on in 1ms and off in 11ms. This provides fast control for most applications.
- Are status indicators available?
- Yes, each channel has an LED. It lights when the output is active.
