Description
The NI-9870 model, bearing the part number 198850D-02L, falls under the category of Industrial Communication Interfaces. This device is specifically designed for serial communication, featuring 4 RS232 ports, enabling it to handle multiple connections simultaneously. The NI 9870E is available as a board-only configuration, tailored for applications requiring serial, RS232 connectivity across four ports.
To power the device, an external power supply ranging from 8 to 28 VDC is necessary. Each of the serial ports on the NI-9870 is isolated from other modules in the system, ensuring secure and reliable communication. In terms of environmental protection, there are two versions available with regard to conformal coating: those being 779891-02 (No) and 779891-03 (Yes), providing options based on operational requirements.
The device boasts individual 64 B buffers per port, optimizing data handling efficiency. Furthermore, it supports baud rates up to 921.6 kbit/s per port, with a maximum data rate of 2 Mbit/s between modules and CompactRIO, ensuring rapid data transfer capabilities. Despite its high performance, the NI-9870 maintains low power consumption, with a maximum of 0.5 W in active mode and as little as 50 µW during sleep mode.
As for accessories, the product includes a PC-MF4-PT link, facilitating easy integration. The maximum cable length supported is equivalent to 250 pF, which accommodates a range of installation needs. Lastly, the NI-9870 is designed to be compatible with NI software, ensuring seamless operation within NI ecosystems.
