Description
The National Instruments NI-9870 C Series Serial Interface Module, part number 195926B-01L, falls under the category of Industrial Communication Interfaces. This module is designed to provide a robust solution for applications requiring serial communication.
It features a 4-port RS-232 interface, allowing for multiple serial connections to be managed simultaneously. The NI-9870 is notable for its efficient power consumption, requiring a maximum of 0.5 W during active use and as little as up to 50 μW in sleep mode. It operates with an external power supply within the voltage range of 8 to 28 VDC.
Each of the four ports on the NI-9870 is equipped with an individual 64 B UART FIFO, facilitating smooth data transfer. The module supports a baud rate of up to 921.6 kbit/s per port, with a maximum data rate of up to 2 Mbit/s between modules and CompactRIO systems, ensuring rapid communication for industrial applications.
Designed to withstand challenging environments, the NI-9870 operates within a temperature range of -40 °C to 70 °C and can be stored in temperatures ranging from -40 °C to 85 °C. Its robust build is further evidenced by its ability to handle vibration of 5 grms (random) and 5g (sinusoidal) at 10 to 500 Hz, making it suitable for use in demanding industrial settings.
The module weighs 5.4 oz, making it a compact yet durable option for integrating serial communications into a variety of projects. Its compatibility with National Instruments software ensures a seamless integration into existing systems, highlighting its flexibility and ease of use for professionals in the field.
