KH501 Intelligent Tachometer & Frequency Meter

Model:KH501

Product details:

　　KH501 intelligent tachometer or frequency meter is high-precision measurement and data acquisition compatible. The meter can measure kinds of physical parameters such as speed, wire-speed, frequency, length etc. The meter adopts omnipotent input with kinds of input signals. It also adopts modern advanced modular structure output functions such as relay alarm, communication, transmission and feed etc, can be configured flexibly. The alarm output function can be configured flexibly as high limit, low limit, higher limit, lower limit. Pulse input can be maximum 30KHZ. Modern universal MODBUS communication protocol is available, with maximum baud rate 19200 bit/s
