Overview

(1)Input signal:Speed sensor, level pulse(low level:-30V~+0.8V; High level:+4V~+30V)；

(2)External sensor: photoelectricSpeed sensors, magnetic speed sensors, encoders, etc;

(3)The instrument is supplied externally to the sensorDC12V/50mADC power supply;

(4)The instrument can set the magnification, display the decimal point, and meet the requirements of measurement accuracy and linear velocity measurement. display value=Number of pulses input per minute multiplied by magnification, range of magnification0.0001~9999；

(5) Two way relay alarm, which can be set as upper and lower limit, upper and upper limit, lower and lower limit alarm or remote control output;

(6)Instrument function parameter values and alarm parameter values will not be lost in case of power failure;

(7)Analog transmission output(DC4~20mATheDC0~20mATheDC0~5VTheDC0~10V)The measurement speed values corresponding to the transmission low limit and transmission high limit can be set.

(8) RS485Communication, standardsModbus-RTUProtocol, can be directly connected withPLCTheHMINetworking of industrial configuration software;

(9)Measurement display range:0~999999；6bit0.56Inch red digital display;

① Input signal type: N input interface is NPN type; The P input interface is PNP type.

② The output code for analog transmission is D, and if there is no such output, it is empty.

③ The RS485 digital interface code is R, and if there is no such output, it is empty.

④ Relay alarm output: One relay output code is A, the second relay output code is A2, and no relay output is empty.

Example: The input sensor isNPNtypeEquipped with RS485 communication, dual relay alarm, model: HY504N-R-A2.
