Description
The National Instruments sbRIO-9870 C Series Serial Interface Module, with part number 780922-01, provides four RJ-50 receptacles/ports for RS232 communications, each backed by a dedicated 64-byte buffer to streamline programming. It operates with standard communication protocols including start bit, stop bit, and flow control settings.
An external power supply, denoted as Vsup, is essential for the operation of the RS232 transceiver, and the module supports an RS232 signal voltage range of ±8 V. The sbRIO-9870 is capable of handling baud rates of up to 921.6 kbps, ensuring rapid data transmission.
This module can function in two different modes: an active mode, where it consumes 0.5 W of power, and a sleep mode, which greatly reduces the power consumption to a mere 50 µW. It is designed with robust safety features, being able to withstand voltages of ±25 V for receive signals and ±13.2 V for transmit signals relative to COM. Furthermore, it offers a significant isolation overvoltage protection of 1000 Vrms between any port and earth ground, ensuring operational security and longevity.
