An optional IS barrier allows “hot” sensor replacement in rated locations. This allows the user to install pre-calibrated/pre-configured sensor boards without removing unit power while maintain EX rating. Removable circuit board stack and detachable connectors facilitate field wiring installation. Features Dual sensor interfacing to enable like-sensor redundancy or control or dissimilar sensor types back lighted LCD for gas level/unit parameter display Four alarm/fault relays configurable for alarm set points, latching and multi sensor relay logic An isolated RS485 Modbus interface provides reliable communication in noisy environments and eliminates “ground Loop” problems Three magnetic switches for local configuration and calibration without compromising explosion proof protections Time stamped date logging using a removable non-volatile memory module. Module can be removed from the unit to allow remote data downloading and data archiving. Dual sensor interface capability Explosion proof Back lighted LCD display Low cost Plug and play toxic, oxygen and combustible gas sensors Self check system 4-20 mA output RS-485 interface (isolated) Alarm and fault relays Non intrusive configuration Non intrusive calibration Removable, non volatile, time stamped data logging memory stick Optional IS barrier Digital communication link to SEC 3000, SEC 3300, SEC 5000 and Millenium gas detectors Multi port housing for easy installation Applications Petrochemical refineries Compost facilities Semi conductor Mining Pulp and paper mills Oil rig platforms Buildings Automotive industry Engine test rooms Sewage Parking garages Specifications Outputs Digital: RS-485 LAN Analog: 4-20 mA source type, max 1000 ohm load at 24 VDC supply voltage Relays: 3 alarm & 1 fault Display Back lighted LCD, LEDs for relay indication Detection Method Toxic: Electrochemical Combustible: Infrared Operating Voltage 18 to 32 VDC Operating Current 314 mA Max @ 24 VDC Power Consumption Nominal: 1.2 W Relays: Add 1 W Heater: Add 5.9 W Temperature Rating -40 to +40°C Humidity 0-99% rH non condensing RFI Built in filter reject RFI/EMI Housing Epoxy coated aluminum Certification CSA/NRTL CI I, Div 1, Groups B, C, D T5 Dimensions 5.25″ W x 5.3″ L x 4.95″ H Weight 6 pounds Gases & Ranges Gas Range Ammonia 0-200 ppm Arsine 0-1,000 ppb Bromine 0-2 ppm Carbon Monoxide 0-100 ppm Chlorine 0-10 ppm Chlorine Dioxide 0-2 ppm Diborane 0-1,000 ppb Ethylene Oxide 0-20 ppm Fluorine 0-2 ppm Formaldehyde 0-20 ppm Germane 0-1,000 ppb Hydrogen 0-1,000 ppm Hydrogen Chloride 0-20 ppm Hydrogen Cyanide 0-20 ppm Hydrogen Fluoride 0-10 ppm Hydrogen Peroxide Call Hydrogen Selenide 0-1,000 ppb Hydrogen Sulfide 0-100 ppm Nitric Oxide 0-100 ppm Nitrogen Dioxide 0-15 ppm Oxygen 0-40% Vol Ozone 0-2 ppm Phosgene 0-2 ppm Phosphine 0-1,000 ppb Silane 0-20 ppm Sulfur Dioxide 0-20 ppm Unit Status Chart Current Output Status 4-20 mA Normal measuring mode 0.0 mA Unit fault 0.8 mA Unit warm up 1.2 mA Zero drift fault 1.6 mA Calibration fault 2.0 mA Unit spanning 2.2 mA Unit zeroing 4.0 mA Zero gas level 5.6 mA 10% of full scale 8.0 mA 25% of full scale 12 mA 50% of full scale 16 mA 75% of full scale 20 mA 100% of full scale >20 mA Over range (>100%) Ordering Information For pricing, please call AFC International at 1-800-952-3293, 219-987-6825 or fax 219-987-6826 or email firstname.lastname@example.org.
