FAQ

Q: When should I use 4-channel vs. 8-channel or 16-channel modules?
A: Use FS-SDOL-0424 for applications with 1-4 actuators where cost optimization is important. Use higher-density modules for larger actuator counts.

Q: Can this module be mixed with other output types in the same chassis?
A: Yes, different output modules can be installed in the same I/O chassis as long as slot assignments are properly configured in the engineering software.

Selection Tips

• Use for small actuator groups or distributed I/O points
• Verify total current requirements against module rating
• Consider spare channels for future expansion
