Description
The NI-9977 is a C Series Slot Filler designed for use in CompactRIO and CompactDAQ Chassis, carrying the part number 151539A-03L. This product is also recognized under other part numbers, including 196917-01, 196917-51, 196917B-01L, and 196917C-01L. It falls under the category of C Series I/O Accessories.
The NI-9977 serves a critical function despite being a non-functional, blank C Series module. Its primary purpose is to fill empty slots in any C Series chassis model, such as the NI 9242 voltage input module, thereby protecting the system from debris and dirt. This not only helps in maintaining the system’s quality and performance but also shields potentially hazardous voltages of the NI-9242 from human contact, adding an important safety feature to the chassis.
For installation, it accommodates wires ranging from 12 AWG to 14 AWG, 16 AWG, and 18 AWG to 24 AWG. The NI-9977 weighs approximately 4.4 oz, making it a lightweight addition to enhance the functionality and safety of the CompactRIO and CompactDAQ systems.
