Description
The product with the part number 198850C-02L falls under the category of Single-Board RIO Modules. Specifically, it is the sbRIO-9870 model, which is an NI 9870E 4-PORT RS232 Serial Module Board-Only. This module is designed to facilitate communication with RS232 devices, featuring 4 RJ-50 receptacles/ports for such connections.
Each port on this module is equipped with a 64 B buffer, ensuring efficient data handling and transmission. To operate the RS232 transceiver, an external power supply is required. The RS232 signal voltage range supported by this module is ±8 V, and it can handle baud rates of up to 921.6 kbps, offering high-speed data transmission capabilities.
When it comes to power consumption, the sbRIO-9870 is highly efficient. In active mode, it consumes only 0.5 W of power, while in sleep mode, the power consumption drops significantly to just 50 µW. This makes it an energy-efficient choice for many applications.
The module exhibits excellent voltage tolerance, with the ability to withstand ±25 V receive signal-to-COM, ±13.2 V transmit signal-to-COM, and ±28 V between Vsup and COM. Furthermore, it offers a high level of safety, featuring an isolation overvoltage protection of 1000 Vrms between port and earth ground, ensuring the module’s integrity and protecting the connected devices from electrical surges.
