Installation Guidelines

1. Install the Power/Controller carrier on a T-type DIN rail.
2. Connect bulk power (12 V or 24 V) to the carrier terminals.
3. Insert the KJ1501X1-BA1 into the power slot until fully seated.
4. Verify LED indicators for power-good status before energizing downstream modules.

Selection Tips

• Choose KJ1501X1-BA1 when you need a dual-input power supply for DeltaV M-series or S-series controllers.
• Calculate total I/O power draw to ensure the 13 A / 8 A output capacity is not exceeded.
• Pair with a redundant carrier if fault-tolerant power is required.
