Description
The sbRIO-9870 is a notable product from National Instruments, identified by its part number 198850B-02L. This device falls under the category of Single-Board RIO Modules and is specifically designed as a C Series Serial Interface Module. It is engineered to be compatible with NI CompactRIO systems, making it a versatile option for a wide range of applications.
The module features 4 RJ-50 receptacles for RS232, each with a buffer size of 64 B per port, allowing for efficient data transfer and management. The power supply required for the RS232 transceiver is external, ensuring the module can be tailored to various power setups. It supports an RS232 signal voltage range of ±8 V, making it robust for industrial applications.
The baud rate capability of this module is impressive, with support for speeds up to 921.6 kbps, allowing for high-speed data communications. Regarding power consumption, it operates efficiently, consuming only 0.5 W in active mode and a mere 50 µW in sleep mode, highlighting its energy efficiency.
In terms of electrical robustness, the voltage tolerance specifications are comprehensive, with ±25 V receive to COM, ±13.2 V transmit to COM, and ±28 V between Vsup and COM. This level of tolerance ensures the module’s reliability and longevity in challenging electrical environments. Furthermore, it offers isolation overvoltage protection of 1000 Vrms, providing an additional layer of safety and security for both the module and its connected components.
