Key issues (3, with different focuses)

Question 1: What are the core hardware differences between sbRIO-9612 and the same series 9611? Why is 9612 more suitable for high-performance embedded scenarios?

answer:

9612: 400MHz processor, 2M gate FPGA, 128MB DRAM, 256MB storage

9611:266MHz, 1M gate, 64MB DRAM, 128MB storage

9612 doubles its computing power and memory, making it more suitable for high-speed data acquisition, complex algorithms, and real-time multitasking control.

Question 2: What are the electrical restrictions on the 24V industrial DI/DO of sbRIO-9612? What is the maximum output current of DO?

answer:

DI: ≤ 5V=off, ≥ 10V=on, current filled type

DO: Source current type, external power supply 6-35VDC

Single channel maximum current: 250mA (without heat dissipation); 1.5A (with heat dissipation)

Maximum total output: 20A

Question 3: sbRIO-9612 does not have built-in AI/AO. How can analog acquisition and output be achieved? What scenarios are applicable?

Answer: AI/AO/thermocouple/IEPE/relay and other functions can be achieved by external connection of 3 C-series I/O expansion slots to the onboard C-series module. Suitable for embedded scenarios such as OEM equipment, vehicles, robots, distributed data collection, etc. that require small volume and customizable I/O.
