EasyMon Gas Monitoring System

EasyMon is microcontroller based multichannel gas monitoring, alarm annunciation and data logging system for any Toxic, Combustible, Oxygen detectors. Every channel has independent 3 digit 7 segment display, keyboard, LED indications, Relay O/P, Analog O/P and optional standard MODBUS output over RS485/RS232 serial port for PLC/SCADA systems.

Features:
  • Universal 1 Channel variable inputs per card, rack expandable to 4, 8, 12, 16… etc.
  • 8 Cards fit into 3U/19” standard rack.
  • Input can be in current (4 - 20mA) or voltage (1 - 5V) form.
  • Card hot swap feature is available.
  • Configurable 2 Alarm levels, relay output type energized/de-energized & Inhibit channel (alarm relays get bypassed at the time of maintenance).
  • Software Zero and Calibration of Analog input can be done through provided keypad (no trim pots).
  • 4 to 20mA retransmission output for PLC, DCS, any recorder.
  • LED indications: 6 LEDs (Red, Green & Yellow) for indicating Power ON, channel Low alarm, High alarm, Over Range, channel fault & channel Isolation.
  • Potential free Relay outputs for Low alarm, High alarm, fault and common (for panel hooter).
  • 3 Digit 7 Segment display to View LEL value.
  • Optional RS-485/RS232 standard MODBUS output to connect with PC/PLC/DCS/SCADA software.
