Features
  • PNP-to-NPN output conversion: Converts a PNP open-collector sensor signal into an NPN open-collector output for equipment with different input requirements.
  • Ultra-compact inline design: The small housing can be installed directly between the sensor and input device, allowing it to be used much like part of the sensor cable.
  • 12–24 VDC operation: Supports a 12–24 VDC ±10% power supply for integration with common industrial sensors and automation equipment.
  • 80 mA NPN open-collector output: Provides NPN open-collector output rated for sink current up to 80 mA at 30 VDC or less.
  • Easy equipment interface integration: Useful for sensor replacement, equipment maintenance, control-interface standardization, and systems where PNP sensor outputs must connect to NPN inputs.

Specification notes

  • The NP-7398 is specifically designed to convert PNP output to NPN output. For NPN-to-PNP conversion, use the PN-7300.
  • The NPN open-collector output is rated for a sink current of up to 80 mA at 30 VDC or less. Connected loads and control inputs must remain within this rating.
  • Short-circuit protection is not provided. Short-circuiting the output may damage the output transistor, so wiring should be carefully checked before operation.
FAQ

Q1: What is the NP-7398?
A: The NP-7398 is a sensor output conversion unit that converts a PNP open-collector input signal into an NPN open-collector output.


Q2: Can the NP-7398 convert a PNP sensor to NPN output?
A: Yes. It is installed between a PNP-output sensor and the control input to convert the PNP signal to NPN.


Q3: Can the NP-7398 convert NPN output to PNP?
A: No. The NP-7398 is designed only for PNP-to-NPN conversion. Use the PN-7300 for NPN-to-PNP conversion.


Q4: What power supply does the NP-7398 require?
A: It operates on 12–24 VDC ±10% with ripple of 10% or less.


Q5: What is the NP-7398 output rating?
A: It provides NPN open-collector output rated for sink current up to 80 mA at 30 VDC or less.


Q6: What is the current consumption?
A: Current consumption is 5 mA or less.


Q7: What are the cable lengths?
A: The input-side cable is 500 mm long, and the output-side cable is 2000 mm long. Both use 0.15 mm² × 3-core cable.


Q8: What applications is the NP-7398 suitable for?
A: It is useful for sensor replacement, equipment maintenance, control-interface standardization, and connecting PNP-output sensors to equipment requiring NPN inputs.


Q9: Does the NP-7398 have short-circuit protection?
A: No. Short-circuit protection is not provided, and a short circuit may damage the output transistor.


Q10: What are the protection rating and operating temperature?
A: The NP-7398 is rated IP64 and operates from -25 to +55°C in non-freezing conditions.
