Speed Switch XLDH-F-III


● Adoption of high-strength A-alloy precise die-casting shell, with strong impact resistant capability.
● The surface of the shell is sprayed with plastic and has strong corrosion resistance.
● The shell has high protection level, good sealing, waterproof and dust-proof, and can be used in harsh environment.
● Using ARM MCU as control unit, it has fast response speed, high precision and small error.
● Non-contact, non-fragile components, long service life.
● Double-row digital tube display, LED indicator display, convenient for on-site observation and maintenance.
● Integral design, two bolts fixed, easy to install and use.
● Intelligent design without manual setting of initial parameters.
● High Precision 4-20mA Analog Output.
● Light and heavy alarm double switch output, light alarm with power off alarm function.
