Monicon - 4 Channel Gas Monitor - Brochure

• Individual voltage free relay contacts• Advanced digital readout• User programmable• Low power consumption• Built-in battery backup circuit• Alarm inhibit during calibration• Individual 4-20mA analogue outputs• Extensive fault detection ?rmware• Sealed to IP65 rating• RS485 communications interface• Remote reset and accept terminalsDigital Signal ProcessingMonicon have pioneered a novel approach to signi?cantly reduce false alarms by processing the sensor signal through an advanced analysis program in the microprocessor. Monicon’s digital signal processing algorithms are an innovative approach to compensate for the undesirable effects of RFI, Humidity changes, EMI, pressure changes, vibration and electrical noise.Automatic self-testThe microprocessor implements a comprehensive self-test routine, continually monitoring the system’s performance and functionality. The self-test routine examines the integrity of the system’s electronic circuitry, system software, sensor cabling, sensor signal, ancillary cabling etc. In the unlikely event of a fault, the digital display will indicate the nature of the condition in a user-friendly diagnostic mode.The Monicon 4 Channel Gas Monitor is an innovative, cost effective, wall mounted unit. It is designed to operate in conjunction with the T100 toxic gas detector and the highly successful CGS500 combustible gas sensor to monitor a range of toxic gases, combustible gases and oxygen in a wide range of applications. It will also operate with an IR100 infrared gas detector.The 4 Channel Gas Monitor is also compatible with a wide range of third party 4-20mA transmitters including temperature probes. The gas concentration is indicated on a 4-digit, 7-segment display while another 2-character alphanumeric display indicates instrument status. A third display indicates the active channel.Simple to use and microprocessor controlled, the 4 Channel Gas Monitor is menu assisted and fully user programmable for alarm setpoints, relay options, range, sensor type, gas type and many other parameters in a user friendly manner offering unique ?exibility and control over the system.The Monicon 4 Channel Gas Monitor has a built-in battery trickle charger circuit and an optional 12V, 1.2AH rechargeable battery (sealed lead-acid type) may be ?tted inside the enclosure to ensure uninterrupted operation in the event of a mains power failure. Careful product design and rigorous product testing combined with a stringent ISO9002 quality assurance program at Monicon’s state-of-the-art manufacturing facility ensure ultimate reliability. The Monicon 4 Channel Gas Monitor offers a robust, easy to use, cost effective approach to providing an effective gas monitoring system where safety matters.4 Channel Gas MonitorMechanical Speci?cationsHeight 230mmWidth 300mmDepth 110mmWeight 3.5Kg (including optional 1.2AH battery, if ?tted)Mounting holes 4 holes, Ø4.2mm, spaced at 200mm (vert) 288mm (horz)Environmental Speci?cationsOperating temperature -18°C to +66°CStorage temperature -40°C to +66°CHumidity range 10%RH to 90%RH (Non-condensing)Electrical Speci?cationsSupply voltage 230Vac (115Vac optional)Power consumption 6WMains fuse 1A’T’Transformer secondary fuse 1A PCB mounted 5 x 20mm fuse Battery fuse 1.5A PCB mounted, auto reset, PTC fuseSensor cables 3 core, screened, 0.5mm2 to 1.5mm2Relay contacts SPDT, 250V, 3A each for A1, A2, Common A3 & FAULT (10 relays)Analogue outputs 4-20mA into maximum 250 O for each channelRS485 operating mode Slave mode, half duplex, polledMax. units on RS485 loop 25 controllers (100 channels)RS485 communications parameters 1200-N-8-1RS485 error checking 1 byte checksumUnit interrogation time 40mSBattery operation time 1.2AH battery: typically 2 hours with all 4 detectors ?ttedBattery voltage 12VBattery type Sealed lead-acidCombustible gas sensor type Monicon CGS500 or compatible third-party sensorToxic gas sensor type Monicon T100, or compatible 4-20mA transmitterStabilisation time User selectable between 1 and 255 secondsAnnunciator output 2.5kHz, 84dB(A) @ 1mTransient protection PCB mounted Metal Oxide VaristorTerminations PCB headers & detachable terminal blocks up to for 1.5mm2 cableOption setting Digital setting (all options ?tted as standard and user selectable)Alarm setting Digital setting (fully adjustable between 10% and 90% of full scale)Alarm types Energised/de-energised.
