Control unit 2404 is a component of series F&G/ESD 2000, is designed for detection of toxic gas such as: Carbon Monoxide, Ammonia, Hydrogen Sulphide, etc... .
Control unit 2404 interfaces directly with transmitters-sensors with 0-22 mA current output or with Smart Sensors in any configuration, including Intrinsically Safe configuration. This exclusive feature allows the user to connect a wide variety of two, three or 4-wire transmitters available on the market.
Using a single chip microprocessor, present in the entire 2400 family, gives more reliability and accuracy. The microprocessor allows the setting of alarm set points through software commands, instead of using potentiometers.
A two-digit display indicates the detected toxic gas ppm (part per million) on a 00-99 ppm scale and any error codes.
The indicated concentration becomes flashing for ppm values over 99. The operating conditions (Alarm, Warning, Ready, Fault) can also be monitored through double LED indicators on front panel.
The control unit sends both the analogue values and the status of the two input channels to the CPU (CPU Facility 2401) through a high-speed redundant RS 485 serial port.
A complete self diagnosis, made possible by the microprocessor, allows supervision and control of board components functionality, correct operation of internal power supplies triggering, and in the case of failure activates the relevant malfunction outputs or Watchdogs.
To increase the operational safety of the control unit, the logical section (including microprocessor, serial interfaces and internal power supplies) is galvanically isolated from the input/output section from/to the field by opto-isolators.
The control unit makes available, on the connector, open collector outputs for warning, alarm and failure, configurable through DIP switches for FLASHING and NON-FLASHING modes.

The board is fitted with a 32-pin DIN 41612 I/O connector.
