NI CFP-DO-400 Módulo de salida digital de adquisición

Rango de voltaje de salida: 5–30V DC (lógica "1"), 0V DC (lógica "0"), adecuado para varios tipos de cargas.

Capacidad de carga: La corriente de salida máxima por canal es de 500mA, lo que permite la conducción directa de relés peque?os, válvulas solenoides y otros dispositivos.

El tiempo de respuesta de un solo canal es <1ms, meeting high-frequency control scenarios (such as fast start-stop equipment).

Built-in overcurrent and short-circuit protection circuits prevent module damage caused by abnormal loads.

Controls the start/stop of production line equipment (such as conveyor belts and robotic arm movements) and the on/off status of valves (such as pneumatic valves and hydraulic valves).

Drives alarm devices (such as audio-visual alarms and emergency stop indicators).

Outputs pulse signals to control the direction, start, and stop of stepper motors, or switches the drive power of servo motors through relays.

Works with encoder signals to achieve closed-loop motor control (such as speed and position adjustment).

Controls the switching logic of lighting systems and air conditioning equipment, or interlocks with sensors (such as temperature and humidity sensors) to achieve automatic adjustment.

Manages the start/stop status of energy equipment (such as frequency converters and charging piles) to optimize energy distribution.

Serves as the output terminal of a signal generator in laboratories to control the working modes of testing equipment (such as power on/off and signal switching).

The DI module collects equipment status (such as limit switch feedback), and the DO module outputs control signals (such as motor start/stop), realizing closed-loop control of "status monitoring–logic judgment–action execution".

The AI module collects analog signals from sensors (such as pressure and temperature), and the DO module outputs switching signals based on thresholds (such as triggering an alarm relay when the pressure exceeds the set value).

The output cables of the DO module are transferred through the screw terminals of CFP-CB-1 to simplify on-site wiring, while using its signal protection function to improve system stability.

Confirm that the output voltage is compatible with the load (5–30V DC), and check the channel configuration in NI MAX software.

Measure the load current. If it exceeds 500mA, external relays are required for capacity expansion.

Re-tighten the wiring terminals and check if the cable is open-circuited.

Add a shielding layer to the output cable and ground it at a single point, keeping it away from strong electromagnetic sources (such as frequency converters).

Check if the load is short-circuited or overloaded, and restart the module to clear the protection status.

Measure whether the chassis power supply (24V DC) is stable, and try replacing the power supply port.

If the fault persists, contact NI technical support for hardware detection or module replacement.
