Frequently Asked Questions (FAQ)

Q1: Is this 1746-NLB module an original Allen-Bradley product or a compatible replacement?

A: The 1746-NLB module we supply is a compatible replacement designed to meet or exceed original specifications. It is manufactured by a third-party vendor with strict quality control, ensuring reliable performance. We also offer genuine Allen-Bradley parts upon request (please inquire for availability).

Q2: Which SLC500 chassis models are compatible with this module?

A: This module is compatible with all standard SLC500 chassis, including 1746-A4, 1746-A7, 1746-A10, 1746-A13, and 1746-A17. It fits into any open slot and draws power from the backplane.

Q3: What do the LED colors indicate?

A: The two LEDs are user-configurable via the SLC500 processor programming. Typically, one LED can be assigned to indicate processor run/stop, while the other can signal a fault condition. The red and green colors are interchangeable based on your ladder logic.

Q4: Does the module require any external wiring or power supply?

A: No external wiring is needed. The module receives 5V DC power directly from the SLC500 backplane. Just insert it into the chassis and it is ready to use.

Q7: Can I use this module in a 1746-NB?

A: No, the 1746-NLB is specifically designed for the SLC500 system. It is not compatible with the 1746-NB (which is for ControlNet communication). Please verify your system model before ordering.

Q8: Do you provide technical support for programming the LED functions?

A: Yes, our technical team can assist with basic programming guidance. However, for detailed application support, we recommend consulting the SLC500 programming manual or contacting Rockwell Automation.
