6� Functions
KRN50 recorder is able to measure Thermocouple, RTD, voltage
(1VDC, 10VDC, 50mVDC, 200mVDC), current(DC 0 to 20mA, DC 4
to 20mA) signal by total 2 input channels. Measured signal records by
digital and graph type through setting a variety of recording speed.
● Alarm
Input 1 channel can have 2 alarm outputs. Alarm output is operating
by a kinds of modes (None, Latch, Stand-by, Latch+Stand-by)
through High-limit, Low-limit, Sensor break, Paper end function.
Alarm outputs by relay contact.
● Recording
Measured signal records by digital and graph type. Recording
speed is able to set by 5sec to 99min 59sec in case of digital mode
(Numerical record) and by 10 to 960mm/h in case of graph mode. It
has memo function recording data at the necessary time and is able
to output time, date, alarm information, error message, parameter list
and so on.
● Display
Measured value is indicated by number on LCD display and time,
alarm, error information, etc. are displayed.
● Communication function
It is able to use RS-485 communication and communication protocol
uses Modbus RTU and communicates with the upper devices, PC or
PLC.
● Data backup function (Record Back-up)
It is similar to data logger function. In case of graph mode and
10mm/h recording speed, approx. 10-day-data is able to be saved in
EEPROM memory. Therefore user can output the saved data from
the memory by graph or digital type. Also even though chart paper is
exhausted all, data is able to be saved to the saving space according
to recording speed.
● Other functions
Feeding function and recording run/stop function are able to be used
by front key or communication at the status of recording stop. Also
recording reservation function is able to start or stop recording at the
suitable time period user wants.
