Frequently Asked Questions (FAQ)

• Q: What is the maximum inrush current this module can handle?
  A: It can handle a surge current of 4A for 10 milliseconds per point.
• Q: Does this module have built-in electronic protection like fuses?
  A: No, the 1746-OBP8 does not include electronic protection. You need to provide external protection.
• Q: Can I use this module to directly control an AC motor?
  A: No, you must use an interposing relay to isolate the DC output and control the AC load.
• Q: What do the LED indicators on the module show?
  A: The e-fuse LEDs show the current state of each output, helping with quick diagnostics.
• Q: How is the module grouped for wiring?
  A: The eight outputs are divided into two groups of four, each with a common terminal.
