Feature: 1. Copy function: When the pressure switch is energized, the set value of a main side sensor can be copied to the side sensor, and at most 10 pieces of them can be copied at the same time. The minimum transmission distance is 4M. Copying requires the use of a dedicated communications line. 2. Stable work: Practical anti-vibration function, and you can adjust the response time to avoid malfunctions caused by rapid pressure changes. 3. Safe to use: The working voltage is 12-24V DC and the rated working pressure is 0-101kPa, so the air pressure regulator ensures good working safety. 4. Good material: Adopting premium ABS material, the pressure switch with digital display and 1/8" RC thread has high precision and reliability. 5. Easy to install: Comes with light weight and compact size, the Convenient installation can be quickly completed in a few minutes Specification: Item Type: Digital Pressure Switch Operating Voltage: 12~24 VDC 10% Consumption Current: 40mA Switching Output: PNP Open Collector 1 Output Load Current maximum: 80 mA Maximum applied voltage: 28 V Response time: 2.5 ms Recommended rated pressure range: 0 ~ -101 kPa Setting pressure range: 10.0 ~ -105.0kPa Withstand voltage test voltage : 500kPa Minimum setting unit: 0.1kPa Suitable fluid: for air, non-corrosive gases, non-combustible gases Interface thread: RC 1/8in Package list: 1 x Digital pressure switch 1 x Connection cable 1 x Manual of the user
