I. Overview
SZC-04 intelligent tachometer, with 5-digit 0.8-inch digital display, one current output, three relay alarm outputs and alarm indicator lights, and RS485 communication; It can be matched with NPN-OC output switch type speed sensors and magneto electric speed sensors. In addition to detecting general speeds, it can also measure ultra-low and ultra-high speeds. It is an intelligent speed display control instrument.
SZC-04 intelligent tachometer 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 specification diagram is as follows

Ordering instructions:
The basic functions of SZC-04 intelligent tachometer include 5-digit 0.8-inch digital display, one current output, three relay outputs, alarm indicator lights, and RS485 communication; The power supply is determined by the specifications. If there is no specification number at the time of ordering, the corresponding commonly used specification is SZC-04- AC. In addition to basic functions, the power supply is 85-250V, AC;
Example of ordering specifications: Specification SZC-04- DC, in addition to basic functions, the power supply is 18-32V, DC.
