FAQ

Q: Can I power this supply from a 24 VDC plant bulk source?
A: Yes. The KJ1501X1-BC4 accepts either 12 VDC or 24 VDC input and automatically regulates the output bus.

Q: Is this module hot-swappable?
A: No. Power must be de-energized before removing or inserting the supply to prevent arcing and bus damage.

Q: What is the difference between BC4 and BB1/BA1?
A: The BC4 is a dual DC power supply with similar form factor to the BB1/BA1 series. Verify your carrier power budget and keying before selecting.

Installation Guidelines

1. Mount the Power/Controller carrier on a T-type DIN rail.
2. Connect bulk 12 VDC or 24 VDC to the carrier field terminals.
3. Align the KJ1501X1-BC4 with the carrier slot and press firmly until seated.
4. Do not remove or insert while system power is energized.

Selection Tips

• Use KJ1501X1-BC4 when your bulk power is 12 VDC or 24 VDC and you need a dual-input supply for M-series controllers.
• For dual-redundant power architectures, install two supplies on a redundant-capable carrier.
• Confirm carrier width (2-wide vs. 4-wide) before ordering.
