RMC685 high accuracy transmitter for temperature
and process applications
• RTD, thermoelements, CU10 , 0/4...20 mA or 0...5/10V, mV, ohm
• Analog output 0/4...20 mA or 0...5/10V
• Serial output RS-485, Modbus RTU or Nokeval SCL protocol
• Mathematical functions
• 10-points linearization table
• Input sampling time up to 100 samples/s for serial output
• Two row text display can be shown user’s own messages
• Configuration by front keys or series bus from PC
• Free calibration certificate can be loaded from our website
• Voltage supply 15V for two wire transmitter
• Power supply supply 24 VDC

RMC685 has been designed for temperature sensors and process inputs in where high accuracy is
required. The display screen is useful for users in where process information is necessary. Further
it can be used for configurations or showing messages to users. Several message screens can be
created which are selected by front keys select them easily by front keys. The configuration can
be made without programming devices by using front panel keys or the MekuWin configuration
program via serial bus RS485 from PC. Mathematical functions and linearization can be created by
MekuWin configuration software.
The measuring speed can be as many as 100 measurings per second when the output is a serial bus RS485. The measuring
speed of the transmitter gives the opportunity to use transmitters in the applications where the simultaneous measuring with
the separate transmitters is important. It is simple to write the mathematical functions or operational conditions on the configuration programme MekuWin. Several different views or messages which the user can choose easily with buttons can be set
on the display screen.
