Description
The NI-9426 is a C Series Digital I/O module designed to meet the needs of a wide range of digital input applications. It comes in two versions: the Conformal Coated version with a part number of 780030-01, and the Non-Conformal Coated version with a part number of 780030-02. This module is specifically designed for sourcing digital input signals, as indicated by its full description, the NI 9426 w/DSub Sourcing Digital Input Module, Conformal Coat.
The module features 32 digital input channels, accommodating a variety of signal types. The input voltage threshold is greater than 1.9 V, with an input current requirement of over 65 μA. It boasts an input impedance of 30 kΩ (±5%), ensuring reliable signal detection and processing. The NI-9426 is capable of a maximum update time of just 7 μs, allowing for high-speed data acquisition and control applications.
Regarding electrical specifications, the Vsup-to-Channel Voltage must not exceed 30 VDC maximum, ensuring the module’s protection against higher voltages. Power consumption is optimized for efficiency, consuming 615 mW during active operation and dropping to a mere 5 mW in sleep mode. This module utilizes a 37-pin D-SUB connector, providing a robust and reliable connection for data transmission.
The NI-9426 is built to operate in demanding environments, with an operating temperature range of -40 °C to 70 °C and a storage temperature range of -40 °C to 85 °C. It can function within an operating humidity range of 10% RH to 90% RH (non-condensing) and a storage humidity range of 5% RH to 95% RH (non-condensing). The module can withstand operating vibrations, both random and sinusoidal, up to 5 grms and 5 g respectively, in the frequency range
