FLAME CONTROL CARD 2408
Control unit 2408, a component of series F&G/ESD 2000, interfaces directly to UV, UV + IR, IR + IR flame detectors with 4-20 mA current outputs in any configuration, including Intrinsic Safety. This exclusive feature allows the user to connect the wide variety of 4-20 mA transmitters available on the market. This card, as do all the cards of the 2400 series, uses a SINGLE CHIP microprocessor, which assures a high reliability and accuracy.The microprocessor allows the setting of the minimum time of flame persistence to generate an alarm, (timing confirms the presence of a genuine flame in order not to create a false alarm). This value is programmable from immediate to a maximum of 99 seconds of delay time to generate the alarm.The card is designed with the configuration of the alarm signal in LATCHING mode and the warning signal in the NON LATCHING mode. The card has a 32-pin DIN 41612 connector for link to/from the field (I/O Connector).
Supervised Digital Input 2409
Control unit 2409, a component of series F&G/ESD 2000, is designed for the management of 8 supervised input channels. It is possible to connect to each channel : * Smoke/temperature detection loop * Thermal sensitive cable * Voltage free contacts from devices such as pushbuttons, relays, etc. Main functions can be resumed a follow: * Management of the signals from input channels * Supervision of the line between detectors and the card * Self-diagnostics and functional control. The card monitors the current from the channels and it shows their status, using front panel LED’s: * RED – Alarm activation (ON); normal functioning (OFF) * YELLOW – Fault (ON); Inhibition (FLASHING) The board is fitted with a 32-pin DIN 41612 I/O rear connector
DIGITAL INPUT 2411
Control unit 2411, a component of series F&G/ESD 2000, is designed for the management of 16 digital input lines. A single chip microprocessor controls the acquisition of signals from the field and displays, through redundant LED’s, the operating status of each channel and any malfunction, activating the cumulative input Fault indication; these LED’s are installed on the board front panel. Input signals can be configured in two modes, i.e. Normally Open or Normally Closed in groups of 8 channels, LATCHING and NON LATCHING and, depending on their configuration, when activated, the front panel indications will be respectively FLASHING and NON FLASHING. Board 2411 communicates the status of each connected channel to the CPU Facility (2401) through a redundant high-speed RS-485 serial line. To increase the operating safety of the control unit, the logical section (including microprocessor, serial interfaces and internal power supplies) is galvanically isolated from the input circuits from the field.
DIGITAL OUTPUT 2422
Control unit 2422, a component of the F&G/ESD 2000 series, is designed for management and control of 16 digital output lines (24V dc negative logic, 0.1 Amp for each output line) The output card is designed to have negative logic characteristic in that it sinks current from the load to the user common power bus. The output devices are connected between the positive power bus (24V dc I/O) and the card outputs on the I/O connector.The output characteristics are compatible with a wide range of user-supplied field devices, such as: relays, LED’s, lamps, etc. The single-chip microprocessor present on the 2422 card and in the entire 2400 series receives output command signals (On or OFF value) from the main processor mod. 2401 Facility Module which execute the dedicated logic output (Application Program) and places the updated values in the output table of the 2422 card via a serial line command. The board is fitted with a 32-pin DIN 41612 I/O connector.
SUPERVISED DIGITAL OUTPUT 2420
The 2420 Logic Controller, for F&G/ESD 2400 System, provides eight (8) Opto-isolated Supervised open Collectors Output for the direct activation’s of solenoids, relays, status lamps, xenon beacons, sounder, etc. with maximum load of 2A @ 24VDC. The Output Card is designed to have the positive logic characteristics in that are source current from the positive power bus and the loads. The output devices are connected between the common power bus (OV of the 24VDC I/O) and the card output on the I/O connector. Each Output channel (based on Smart device), has a voltage loop back circuit which verifies the correct operation of the output channel and also detects and indicates the open and short circuit of the load. The output channel will be deactivated when a short circuit is detected (i.e. high temperature or high current >2A). The card, based 8 microprocessor receives output command signal(ON or OFF)from the 2401-CPU Facility Card which executed the dedicated logic output (application program) and places the update data in the Output table of the 2420 Card.
