The part number 777318-304 refers to the National Instruments cFP-DI-304, a 32-channel sinking Digital Input Module designed for Compact FieldPoint systems. This module is essential for monitoring voltage levels of signals in various applications such as limit switches, power circuits, and relay closures. The cFP-DI-304 offers isolation between modules to protect the system/controller from high voltages, with a continuous isolation of 250 Vrms between channels and backplane. It features 32 digital input channels with an impedance of 30 k⦠and a working range of 0~30 VDC. The module also includes 2 analog output channels and is compatible with TTL devices. Equipped with indication lights for each input channel, as well as POWER and READY status, the cFP-DI-304 is powered by the network module and can withstand transient voltages of up to 2300 Vrms for 5 seconds. With a current-limiting feature to prevent damage, the module can update all channels at a rate of 1 kHz and should be externally calibrated at least once a year. Operating within recommended temperature ranges of -40 to 70 °C and -40 to 65 °C when mounted upright or in other orientations, respectively, the cFP-DI-304 also has a storage temperature range of -55 to 85 °C and can withstand non-condensing humidity and various levels of vibrations.
