FAQ

Q: What is the maximum continuous output current per channel?
A: The maximum continuous output current per channel is 0.5 A.

Q: How is over-temperature protection handled?
A: When the temperature exceeds 135°C, the module enters a low-duty cycle PWM mode (selective thermal shutdown) to prevent critical chip temperatures.

Q: What happens if the process voltage drops below 12V?
A: If the process voltage drops below 12V, the process voltage supervision input will trigger an error signal that can be monitored through the ModuleBus.

Q: Can the DO818 module be used with all S800 I/O systems?
A: Yes, the DO818 module is compatible with all S800 I/O systems and can be used with different MTUs, such as TU830, TU818, and TU819.
