Summarize
The frequency transducer, frequency signal will be set according to the user to
convert the linear range 4~20mA (or 0~20mA)output.The product has one relay
alarm output.This product need be supplied independently,and the power
supply,input and output are isolated from each other.

Input signal fault detection function:
If the input signal exceeds the top measuring range set,output current 22mA(or
output voltage 5.5V), the relay aets as the input, SPH LED ON, faceplate display "full".
If the input signal fallen below the measuring range set, output current 3mA (or
output voltage 0.75V), the relay aets as the input, SPL LED ON, faceplate display
"nfull".
If the input signal fault and input signal can't transmission,output current2mA(or
output voltage 0.5V),the relay aets as the input, SPH.SPL ON,faceplate display "no in".
input signal model is: in2.H/in2.r:
If the input loop-current I<0.1mA, proximity switch alarm(break line), output current
2mA,the relay aets as the input,SPH.SPL LED ON, faceplate display "inopn".
If the input loop-current I＞6mA, proximity switch alarm(shout circuit)output current
2mA, the relay aets as the input, SPH.SPL LED ON, faceplate display "insot".
Note: If input signal top limit overflows or lower limit overflows or input signal
faults, the output current can be configured to any value of 0~24mA (0~6V for
voltage) separately.
Start delay time: 0~9999s
When the output relay is set to alarm mode with under-speed, the instrument
will not output an alarm signal during the launch delay time after power on due to the
under speed of input signal.
Input fault response time: 0.1~999.9s
The input signal pattern choice:
in H:Frequency input for NAMUR(2、 3、 4-wire sensor, dry contact
switch,incremental encoders)at Hz.
in r: Frequency input for NAMUR(2、 3、 4-wire sensor, dry contact
switch,ncremental encoders) at min .
in2 H: Switching input for NAMUR,with input wirebreak and input short-circuit
recognition. at Hz.
in2 r: Switching input for NAMUR,switching input for NAMUR,with input wirebreak
and input short-circuit recognition.at min .
Not: If users need to switch measurement display unit, (Hz or min ), you need to
set measuring range、alarm、alarm hystersis and so on.
The LED indicator light instructions:
SPH: If the input signal exceeds the top alarm(contains dead band) LED ON.
SPL: If input signal fallen below the alarm(contains dead band) LED ON.
SPH、SPL ON: Input signal fault.
RAL ON: Output relay closure.
