Description
The NI-9425 is a part of the C Series Digital I/O category and comes under the specific part numbers 779139-01, 785044-01, 780176-01. This module is designed to be a 32-CH 24VDC Sinking Digital Input Module, catering to applications requiring high-density digital inputs. The NI-9425 supports digital I/O logic levels of 12 V/24 V, making it versatile for various industrial applications.
The module features 32 channels that are sinking inputs, providing flexibility in connecting different types of sensors and switches. It boasts a maximum update rate of 7 µs, ensuring quick response times for time-sensitive applications. For connectivity, the NI-9425 offers two types of connectors: spring terminal and D-SUB, which allows for easy and secure connections.
The weight of the module varies slightly depending on the connector type, with the spring terminal version weighing 5.7 oz and the D-SUB version weighing 5.2 oz. This module is built to withstand harsh conditions, operating in temperatures ranging from -40 to 70 °C and storage temperatures ranging from -40 to 85 °C.
Humidity is another factor that the NI-9425 can handle, operating in 10 to 90% RH non-condensing environments, and can be stored in 5 to 95% RH non-condensing conditions. When it comes to durability, the module is designed to withstand vibrations, supporting operating vibrations of 5 grms (random) and 5 g (sinusoidal) in the frequency range of 10 to 500 Hz. This makes the NI-9425 a robust choice for industrial environments where reliability and performance are critical.
