(C Series Engine-Synchronous TTL Output Module)

8-Channel C Series Engine-Synchronous TTL Output Module—The NI‑9754 provides individually controlled 5 V transistor‑to‑transistor logic (TTL) outputs. You can control channels with custom Boolean user logic for tasks such as fuel and ignition commands. The Powertrain Control Device Drivers software provides functions for engine position tracking and complex engine-synchronous fuel/spark commands. The TTL outputs do not produce sufficient current for driving fuel injectors or ignition coils, so you should use them for commands to external custom driver circuits or smart actuators with built‐in driver circuits.
