Hardware Specifications

Backplane Bus Communication and Parallel Operation

The 1606-XLP72E integrates with the 1606-XLP series backplane and supports parallel operation for load distribution. I/O density scaling allows multiple modules to provide higher aggregate current while maintaining stable DC output. Firmware flash compatibility ensures consistent module behavior during system updates.

Frequently Asked Questions (FAQ)

Q: What is the maximum continuous output current?
A: The module supports up to 3 A continuous output at 24–28 V DC.

Q: Can multiple 1606-XLP72E modules be operated in parallel?
A: Yes, parallel operation is supported for higher load requirements.

Q: What type of mounting is required?
A: DIN-35 rail mounting with adequate airflow for convection cooling is required.

Field Installation Guidelines

• Confirm input voltage range before applying power (AC or DC).

• Maintain spacing between modules to allow proper convection cooling.

• Ensure all chassis and signal grounds are connected per industrial standards.

• Route input power lines separately from signal or communication lines to minimize noise.

• During parallel operation, use identical wiring and conductor lengths to prevent voltage imbalance.

• Verify DC-OK LED status after power-up to confirm output availability.

• Periodically check terminal connections to prevent loosening under vibration.
