FAQ

Q: How to choose the output mode of a safety light curtain?

A：

The output mode of a safety light curtain refers to the form in which the safety light curtain converts the signal. There are typically multiple options available, and users can choose based on their specific needs. Here are some common output modes for safety light curtains.

Relay output. This is the most common output mode, where the safety light curtain has a built-in small relay with a set of normally open and normally closed passive output contacts that can be connected to any load.

1. NPN/PNP output: This output mode is commonly used for connecting to digital circuit controllers, where the signal is output in a pulsed manner. Users can select one of the output modes based on their specific needs, and it can be connected to PLCs, PCs, or external relays.

2. Dual NPN output/Dual PNP output: This output mode allows for two load connections, such as PLCs, PCs, or external relays, or can be connected to a safety relay output. It is suitable for various application scenarios.

3. Controller output: The controller can provide the necessary supply for the safety light curtain, and the safety light curtain can direct

to choose the appropriate output mode for a safety light curtain, it is important to consider the specific requirements of different application scenarios. DADISHENG safety light curtains remind you that for situations requiring long-distance signal transmission or remote control, relay output is recommended. For industrial automation applications, NPN/PNP output or controller output can be selected.

Furthermore, users should also consider factors such as safety, stability, and user-friendliness. Regardless of the chosen output, it is crucial to ensure reliability and stability to guarantee the normal operation and safety of the system.

In summary, there are several options for the output mode of a safety light curtain, including relay output, NPN/PNP output, dual NPN output, dual PNP output, and controller output. When selecting the output mode, users should consider the requirements of their specific application scenario and take into account factors such as safety, stability, and user-friendliness.
