XJP-18C Intelligent speedometerDetailed product description：

XJP-18C intelligent speedometer, equipped with a 7-bit 0.56-inch digital display, RS-485/232 communication (MODBUS protocol), one current output, three relay outputs, and alarm indicator lights; It can be matched with NPN-OC output switch type speed sensors and magneto electric speed sensors. In addition to detecting general speed, linear velocity, flow rate, and frequency, it can also measure ultra-low and ultra-high speeds. It is an intelligent speed display control instrument.
XJP-18C intelligent speedometer has 10 sets of user parameters, which can be queried/modified by the operation keys on the panel or computer. The confirmed parameters can be saved for a long time. Satisfying various engineering needs, it has become a truly intelligent instrument.
The manufacturer has combined more than 20 years of professional design and manufacturing experience, applied new design concepts and electronic technologies, and adopted the independently designed dedicated chip TM-090301 as the main chip of the intelligent speedometer. Through module optimization and combination, it covers various specifications of the original XJP-48 series products, and has new expansion and extension in composite functions. This not only improves the quality control level of standardized production, but also facilitates user selection. At present, it has been widely used in industries such as shipbuilding, metallurgy, energy, chemical engineering, electronics, machinery, and automobile manufacturing.
