4-Channel C Series Current Output Module. The NI-9265 is ideal for interfacing and controlling industrial current-driven actuators at high rates. The module has built-in open-loop detection, which generates an interrupt in software when an open loop is detected as well as zeroing outputs to ensure safety and avoid driving actuators at system power on. The NI-9265 requires an external power supply and includes a channel-to-earth ground double isolation barrier for safety and noise immunity.
