It is a FLEX XT 8-point DC output module used to control field devices such as relays, solenoids, and indicators in harsh environments.
Q2. What does “XT” mean in the model number?
“XT” stands for Extreme Temperature, meaning it is designed for wider operating conditions (-20 to 70°C).
Q3. What type of outputs does it provide?
It provides 24 VDC sourcing (PNP) digital outputs.
Q4. Does it have protection features?
Yes, it includes electronic fuse (e-fuse) protection that automatically limits or shuts down faulted outputs.
Q5. How many output channels are available?
It has 8 independent output channels.
Q6. What happens when an overload occurs?
The affected channel is electronically protected and can recover automatically once the fault is removed.
Q7. What environments is it suitable for?
It is suitable for industrial and harsh environments, including outdoor or high/low temperature installations.
Q8. What applications is it typically used for?
It is used in distributed automation systems requiring reliable outputs in harsh conditions, such as mining, oil & gas, outdoor machinery, and process control systems.
