Frequently Asked Questions
Q: What does ‘electronically fused’ mean?
A: Each output has its own electronic protection. This prevents damage from short circuits.
Q: Can I use this for PWM control?
A: Yes! The 1756-OB16IEF module is designed for PWM applications.
Q: What is the minimum load current?
A: The minimum load current is 1 mA per point.
Q: How do I set the fault mode?
A: You can configure the fault mode (Hold, Last State, On, Off) and its duration in the software.
Q: Is this module isolated?
A: Yes, it offers 250V of continuous isolation for safety and noise reduction.
