National Instruments NI-9967 Screw Terminal Strain Relief and Operator Protection Accessory (NI-9242 C Series Voltage Input Module accessory)

The NI-9967 (Part Numbers: 783094-01 and 156514A-01 [Rev A or higher]) is a screw terminal strain relief and operator protection accessory made to accommodate the National Instruments NI-9242 (Part Number: 783107-01) 3-Channel, 24-Bit Voltage Input Module. It is a useful and highly recommended accessory for high vibration and/or high voltage applications. The NI-9967 should be used for applications involving a voltage greater than 42.4 Vpk voltage or 60 VDC to earth ground. The NI-9967 connector back shell accessory ensures that the terminals are not accessible to operators.  

The National Instruments NI-9967 screw terminal strain relief and operator protection accessory is a back shell that attaches to the 4-terminal connector on the NI-9242. The NI-9967 assembly can connect single- or three-phase measurement configurations. 

To install the NI-9967 screw terminal strain relief and operator protection accessory, the following wires may be used: 12 AWG to 14 AWG, 16 AWG, and 18 AWG to 24 AWG. The selected wires determine the method of installation. To install the NI-9967 Using 12 AWG to 14 AWG Wire, Route wires under the smallest strain-relief piece. When installing the NI-9967 using the 16 AWG wire, Route wires between the two strain-relief pieces, with the small strain-relief piece on top of the wires and the large strain-relief piece underneath the wires. To install the NI-9967 using the 18 AWG to 24 AWG wire, Route wires under the largest strain-relief piece. Once wires have been properly routed within the assembly, secure the NI-9967 screw terminal strain relief and operator protection accessory pieces in place using screws. 

The NI-9967 is a terminal accessory that ensures potentially hazardous voltages of the NI-9242 are shielded from human contact. The NI-9967 corresponds to the C series analog input modules. The assembly including the NI-9967 offers several channels for measurements between the neutral and signal channels and between the neutral terminal and ground. The NI-9967 screw terminal strain relief and operator protection accessory for signal wire security and high-voltage protection enables safe operation of the NI-9242.
