Monicon - Multi Channel System - Brochure

• Fully independent operation per channel• Voltage free relay contacts (SPDT)• Open collector outputs• Advanced digital readout• Fully user-programmable• Low power consumption• Digital Signal Processing algorhythm• 4-20mA Analogue Output• RS485 serial data interface• Extensive fault detection circuitry• Up to 16 channels per “Eurorack”Digital 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 com-prehensive self-test routine, continually monitoring the system’s performance and functionality. The self-test routine checks 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 Multichannel Gas Monitor is an innovative, cost effective, rack mounted system. Two control cards are available. Part number C25005 is designed for use with the T100 detector head while Part number C55005 control card is designed for use with the CGS500 or similar thermocatalytic sensor.The Multichannel Gas Monitor is also compatible with a wide range of third party sensors and 4-20mA transmitters including temperature probes. The gas concentration is indicated on a 7-segment digital display while an alphanumeric display indicates instrument status.Simple to use and microprocessor controlled, the Multichannel 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 control cards may be mixed in any combination in a single Eurorack. Inadvertent card transposition may be prevented by the use of special coding strips.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 Multichannel Gas Monitor offers a robust, easy to use, cost effective approach to providing an effective gas monitoring system where safety matters.Multichannel Gas MonitorMechanical Speci?cationsHeight 112mm (4U version: 178mm)Width 25mmLength 222mm (4U version: 200mm)Weight 300g (4U version: 330g)No. of channels per “Eurorack” Up to 16Environmental 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 20-35VdcSupply current (per channel) Normal 80mA, Alarm 120mA @ 24VdcCircuit protection Electronic current limiter, 1A auto-resetRelay contacts SPDT, 230Vac, 3A each for A1, A2 and A3 on each control cardAnalogue output 4-20mA into maximum 500 Ohms (Current source default, current sink option)RS485 operating mode Slave mode, half duplex, polledMax. units on RS485 loop 100RS485 communications parameters 1200-N-8-1RS485 error checking 1 byte checksumUnit interrogation time 40mSCombustible gas sensor type Monicon CGS500 or compatible third-party thermocatalytic sensorToxic gas sensor type Monicon T100, IR100 or compatible third-party 4-20mA transmitterStabilisation time C25005 is variable 1-250 seconds; C55005 is ?xed at 30 secondsTransient protection PCB mounted Metal Oxide VaristorTerminations 32-way F-type connector to DIN41612 standardOption 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.
