Field Industrial Control & Monitoring Product Range:

5000 Series:

  • The Field 5000  series alarm monitor is designed to replace the now obsolete Thermo– Rosemount 4000, 4001, 4002 & 4400 alarm monitors.
  • A Highly versatile process condition monitor capable of the simultaneous reading of up to 24 analogue process signals.
  • The instrument is equipped to handle most process signal types from mA and mV to RTD and Thermocouples with software selectable scaling and linearization’s.
  • Each channel is equipped with software strategies for Alarming and Logging providing the user with an array of possibilities for process monitoring.
  • Dual Alarm outputs with independent set-points and triggering strategies, including; High, Low, Rate of Change and Early Indication.
  • Each Channel has a dedicated microprocessor for high speed data acquisition.
  • The dual channel I/O cards are built on the proven Field 1000PLUS platform and feature high quality analogue components and 24 bit ADC, giving the best accuracy and thermal stability.
  • Analogue Output repeat facility with user defined rescaling available with optional Analogue Output daughter board.
  • Touch-screen interface for Channel card monitoring, local interrogation, alarm acknowledgement and system configuration.
  • Auxillary communications options available for RS232, RS485 (MODBUS RTU/JBUS) allowing 5000 units to be networked and/or interfaced to DCS & SCADA systems.
  • Available in 6, 12 and 24 channel models
