Frequently Asked Questions

• Q: What is the maximum distance this module supports?
  • A: The maximum cable length is 1.5 meters between the first and last interface module.
• Q: Does this module require external power supply?
  • A: No, the module draws 85mA from the 5V backplane bus. No external power supply needed.
• Q: Can I use this module with any S7-400 rack?
  • A: Yes, it works with UR1, UR2, and CR3 racks. Install it in the central rack only.
• Q: What is the difference between Send IM and Receive IM?
  • A: Send IM (IM 460) goes in the central rack. Receive IM (IM 461) goes in the expansion rack.
• Q: Why does this module not have C bus?
  • A: C bus is for communication between CPUs in multi-processor systems. This module is for standard I/O rack expansion only.

Buyer’s Selection Guide
