Frequently Asked Questions (FAQ)

• Q: What does “sinking output” mean for this module?
  A: Sinking configuration means the module provides a path to ground (-) when active, requiring positive (+) power to be supplied externally to the load.
• Q: Can I mix different output voltages within the same module?
  A: No, all 16 outputs share a common power supply and must operate at the same voltage within the 10-50VDC range.
• Q: How often can the surge current capability be used?
  A: At 30°C, you can use the 3A surge current for 10ms once every second; at 60°C, limit it to once every two seconds.
• Q: What wire size should I use for connections?
  A: We recommend using appropriate wire gauges for your current requirements, typically between 22-14 AWG for most applications.
• Q: Does this module provide short-circuit protection?
  A: No, you must provide external protection for short circuits and overload conditions to prevent damage to the module.
