Product Process Transmitter RMA421

Multifunctional 1 channel top hat DIN rail mounted unit with universal input, loop power supply, limit monitor and analogue output.

• Multi functional:
  All normal measurement signals can be directly connected (bipolar voltage and current, thermo-couple, RTD, resistance)
• Operational:
  LC-display with push buttons for front end operation
• Alarm:
  Flexible set point monitorwith 2 changeover contacts
• Active:
  Scaleable current or voltage analogue output
• Power:
  Integrated loop power supply for connected sensors
• Communicative:
  RS232 interface for setting up and measured value output
  HART communication sockets for setting up sensors

The presettable universal input enables direct connection of various sensors, whether current, voltage, RTD or thermocouple. Using the built-in loop power supply the unit can also power the connected sensors and then evaluate the signal returning from the sensor to the input of the unit. Two presettable set points monitor the measured value for any deviation from the preset conditions. This opens up a number of possibilities for direct process control. The scaleable analogue output offers an instrument from which a matched signal for further analysis equipment can be obtained. Simple setting up using an interface and PC programme as well as manual on site setting up are available.
