The NI CB-37F-LP is an unshielded screw terminal block that provides direct signal access to National Instruments data acquisition devices equipped with 37-pin D-SUB connectors. It terminates analog input, analog output, counter/timer, and digital I/O signals through 40 screw terminals, including 3 shielded terminals for noise-sensitive applications. The terminal block mounts directly to compatible NI DAQ device front panels or connects via external 37-pin cable, eliminating intermediate cabling in laboratory, industrial, and educational measurement setups.
