National Instruments 781503-01 C Series Terminal Block.
The part number 781503-01 from National Instruments is the identifying part number for the NI-9923 C Series Terminal Block. For C Series modules that employ 37-pin DSUB connectors, this terminal block is especially helpful when making custom connections. Its ability to connect signals from the C Series module to other devices with simplicity is one of its primary advantages, which makes it a crucial part of test and measurement applications.
The 781503-01 adaptability and usefulness in a range of industrial and laboratory contexts are increased by its compatibility with NI Compact FieldPoint devices. The device is made to guarantee both safety and adherence to applicable laws. It specifically warns against taking the circuit board out of its enclosure or connecting dangerous voltages more than 30 Vrms/42 Vpk/60 VDC to the terminal block. The current rating is dependent on the pin and temperature, with certain pins supporting up to 5 A at temperatures up to 55 °C and others supporting 1 A per channel with a total aggregate of 16 A.
For connection of the C Series Terminal Block, users must follow some rules that includes stripping of insulation for the screw terminal wiring with stripped wire length of 4.5 mm (0.18 in.), then inserting the wire into appropriate terminal and then securing the connections by tightening the screw. The specified torque for screw terminals is a maximum of 0.4 N·m (3.4 lb·in), ensuring that connections are secure and stable, which is essential for reliable operation. This terminal block weighs 82 g (2.9 oz).
The C Series Terminal Block is designed to operate at temperatures of -40 degrees Celsius to 70 degrees Celsius with operating relative humidity of 10% to 90%, noncondensing while its optimum storage temperature is -40 degrees Celsius to 80 degrees Celsius with storage humidity of 5% to 95%, noncondensing. This terminal block does not feature ingress protection which means that it cannot be used where dust and moisture are common. It has a pollution degree of 2 and can installed at maximum height of 2000 meters above sea level at an ambient temperature of 25 degrees Celsius.
