Notices
1.The ultra-thin design (7mm) saves space, but avoid installing in areas with strong mechanical impact.
2.Select the model based on the signal line's nominal operating voltage (5Vdc/12Vdc/24Vdc/48Vdc).
3.The module comes with guide rail ground contact; ensure the DIN Rail is properly grounded.
4.Use wiring with cross-sectional area 0.5mm²-2.5mm² and tighten screws to 1N·m torque.
5.Avoid installing in environments with strong electromagnetic interference to prevent signal distortion.
6.Regularly inspect the module for loose connections or physical damage; replace if faulty.
FAQ
Q1: What is the thickness of the product?
A1: The product thickness is only 7mm, featuring an ultra-thin design to save space in control cabinets.
Q2: What is the function of the guide rail ground contact?
A2: It enhances grounding reliability by utilizing the DIN Rail as a ground path, simplifying installation.
