Description
The National Instruments NI-9753 C Series Differential Digital I/O Module, part number 782133-02, features eight separately controlled I/O channels compatible with RS485/422 and operates across a voltage range of 0 V to 5 V. Users can control the outputs through either user-customized Boolean logic or specialized fuel and spark Vis, which require an Engine Position Tracking (EPT) VI. As inputs, these channels serve as general-purpose Boolean Trigger signals within the LabVIEW FPGA application.
This module requires power from two sources: the CompactRIO backplane via an HD15 connector and an external DB-37 connector. For connections, the NI-9923 Connector Kit is recommended to ensure proper strain relief and secure connections. The NI-9753 also boasts overvoltage protection, allowing the RS485 input/output pins to be shorted to ground, to each other, or to voltages ranging from -7 V to +12 V without sustaining damage. Furthermore, it can tolerate pulses of ±50 V, 15 µs wide, at a 1% duty cycle with a minimum resistance of 100 Ω.
