FAQ

Q: How many I/O modules fit on this carrier?
A: The KJ4005X1-BE1 accepts up to eight I/O modules in a single horizontal row.

Q: What is the maximum local bus current?
A: 15 A at 12 VDC, sufficient for a fully loaded carrier.

Q: Can I mix analog and digital I/O on the same carrier?
A: Yes, provided each module is compatible with the S-Series local bus and keying system.

Installation Guidelines

1. Mount the carrier on a T-type DIN rail using the locking clips.
2. Install the carrier shield bar for grounding and EMI protection.
3. Insert power buss plugs into the field power slots.
4. Slide I/O modules into the slots from left to right, ensuring each latches securely.

Selection Tips

• Order KJ4005X1-BE1 for standard S-Series I/O expansion requiring eight slots.
• Verify total local bus current draw of all eight modules does not exceed 15 A.
• For redundant power architectures, use carriers with dual power feed points.
