SEA 9210 Multifunction I/O Module

The SEA 9210 Multifunction I/O module for NI CompactRIO is an universal, compact and cost-effective solution for applications that require only few channels, but different channel types. The combination of analog inputs, binary in- and outputs and direct FPGA lines makes the SEA 9210 suitable for a wide range of applications, for example:

• Diagnosis and monitoring of autonomous CompactRIO systems (System status, supply status...)
• Supervision of environment parameter (temperature, pressure, humidity, air quality...)
• Supervision of mechanical stress (shock, vibration...)

The module offers 3 analog channels for voltage measurements and 2 analog channels for current measurements (over an external shunt resistor). Two voltage channels and two current channels share a common Analog-Digital converter (ADC) respectively, enabling el. power measurements on two independent channels. The basic function of the analog channels is shown in the image SEA 9210 Analog Input above. The 4 digital inputs can be used to monitor binary system states (e.g. 'Door Open!'). The wide input range offers a great tolerance with respect to the system signal levels. The 4 digital outputs can be used to control system components (e.g. switches, lamps, etc.).
The SEA 9210 Multifunction I/O Module offers direct FPGA lines along with an integrated power source to incorporate devices with digital interfaces. Typically, these devices are digital sensors with a digital SPI, I2C or similar communication interface. These sensors often require an external power supply, which can be provided by the integrated power source of the module. All I/O channels are insulated against the backplane. The principle of function is shown in the image SEA 9210 Block Diagram above.
