Can the Delta DVP08HN11T be used with AC loads?

No, this module features DC transistor outputs (NPN). It is strictly for controlling DC devices.

Connecting AC loads can lead to module damage and electrical hazards. Always verify the load's voltage and type before wiring.

Ensure compatibility; use relays or contactors if AC control is needed. These act as interfaces between the DC output and AC load.

What is the maximum current per output point for the DVP08HN11T?

Each individual output point on the DVP08HN11T can handle up to 0.5A. This rating is crucial for selecting appropriate loads.

Exceeding 0.5A per point may cause overheating and premature failure of the transistor. Always adhere to the specified current limits.

The total module current must also not exceed 2.0A. Consider the combined load current when designing your system.

How do I wire an NPN transistor output module?

For NPN outputs, the load is wired between the positive DC supply and the output terminal. The PLC then sinks current from the load to ground.

The common terminal of the output module should be connected to the negative DC supply (0V). This completes the circuit when the output is activated.

Ensure all connections are secure and that the DC power supply is correctly rated and filtered. Proper wiring prevents shorts and ensures reliable operation.
