Description
Chapter 1.General introductionIt is used to measure and disaply the direct reading of frequency values in the electrical line.It can support the analog output,alarm,RS485 communication function by the installation of different function modules. And it can also select the multiple functional modules at the same time to make it with the functions of measurement,alarm,transmission and communication.
Chapter 2.Model and defintionChapter 3.General parametesMeasuring range | 10.00HZ~300.0Hz |
Input voltage | AC 30V~500V |
Accuracy | ±0.1HZ |
Resolution | 0.01Hz |
Alarm output | relay contact output,contact capacity AC 250V/1A;DC 30V/1A,resistive load |
Communication interface | RS485 serial communication,MODBUS-RTU communication protocol |
Transmitting output | linearity 0.5%,load resistance:output current≤300Ω,output voltage≥1KΩ,which are electrical isolated with the input signal and the auxiliary power supply |
