FAQ
FAQ
Q1. What is the main function of the 1794-OB16P?
It is a FLEX I/O digital output module used to control 16 DC field devices with built-in electronic protection.
Q2. How many output channels does it provide?
It provides 16 independent DC output channels.
Q3. What type of outputs does it use?
It provides 24 VDC sourcing (PNP) outputs suitable for relays, solenoids, and indicators.
Q4. What does the “P” (Protected) mean?
It indicates electronic fuse (e-fuse) protection on each output channel, which automatically protects against overload or short circuits.
Q5. What happens when a fault occurs?
The module limits or shuts down the affected channel and can automatically recover once the fault is cleared.
Q6. What is the maximum output current?
Each channel supports up to 0.5 A, with a total module current of 8 A.
Q7. Does it provide channel-to-channel isolation?
No, it only provides field-to-system isolation, not between individual channels.
Q8. What applications is it typically used for?
It is used in industrial automation systems where output protection is required, such as machine control, conveyor systems, and general-purpose PLC outputs.
