National Instruments 778241-01 Terminal Block 

National Instruments part number 778241-01 is an identifying part number for the TB-2705, a Terminal Block. This Terminal Block is an accessory for 68-pin PXI E Series and S Series devices by National Instruments. It provides easy access to analog signal inputs and supports digital input/output signals. The 778241-01 also includes triggering capabilities and can be accessed with counter/timer signals. The National Instruments 778241-01 Terminal Block is designed for connecting to PXI data acquisition modules. It can be directly attached to the front panels of PXI E Series devices. It is also suitable for connecting waveform generation devices, enabling connections for analog I/O signals, counter/timer signals, and digital input/output signals without the need for additional cables. 

The part number 778241-01 is a terminal block assembly with a printed circuit board, 62 screw terminals, and a plastic enclosure featuring a strain relief. It connects directly to the front panel of National Instruments E Series and waveform generation devices, eliminating the need for an external cable. Moreover, this terminal block allows for easy connection of analog input, analog output, counter-timer, and digital I/O signals to your National Instruments device. The 62 screw terminals provide access to every pin on the device, except for some common digital ground signals. It also includes a shielded strain-relief to secure your I/O wires and ensure a proper chassis-ground connection. 

The NI 778241-01 is not intended for input voltages above 42 V. Even with a voltage divider that reduces the voltage to within the input range of the DAQ device, input voltages over 42 V can damage the Terminal Block, connected devices, and the host computer. Overvoltage can also pose an electric shock hazard to the operator. National Instruments has declared obsolete status for the part number 778241-01, however, it is still available for purchase and repairs at the Apex Waves Website.
