National Instruments 777687-26 GBIB High-Voltage Terminal Block
National Instruments part number 777687-26 is an identifying part number for the SCXI-1326, a High-Voltage Terminal Block with 48 Screw Terminals. The NI 777687-26 is specially designed for high-voltage digital input or output applications, making it ideal for temperature or voltage scenarios with numerous channels. With its shielded Terminal Block, the 777687-26 enables quick and convenient signal connections. This model boasts a maximum voltage of 300 V, falling under Cat II classification. Featuring 48 screw terminals organized into eight groups of six, each group operates independently.
Within a group, terminals include VCC, GND, and four channels, with their functionality varying based on the module. For instance, while VCC terminals aren't utilized with SCXI-1162HV or SCXI-1163R modules, GND terminals remain inactive on SCXI-1162. The role of VCC terminals also differs: they serve as power/reference voltage for SCXI-1162 but function as the power supply (5 V ±0.5 V), referenced to GND, for SCXI-1163. GND serves as the ground reference for SCXI-1162HV, ground for SCXI-1163, and common pole for SCXI-1163.
To set up the 777687-26 system efficiently, you'll need the High-Voltage Terminal Block Installation Guide alongside the 777687-26 high-voltage terminal block, a compatible SCXI chassis, and one of the designated modules: SCXI-1162, SCXI-1163, SCXI-1162HV, or SCXI-1163R. Essential tools include a wire insulation stripper, wire cutter, needle-nose pliers, and flathead and Phillips-head screwdrivers in varying sizes, facilitating proper installation and wiring for seamless operation.
