Appendix — Specifications (cont.)Page 33Channel Expansion ModuleDatataker EnclosuresThe Channel Expansion Module (CEM) connects to the Datataker 500, 505, 600, 605 and Geologger 515, 615 to increasethe number of analog and digital channels. One or two Channel Expansion Modules can be connected to these loggers.All input signal types and sensors supported by the Datataker are also supported by the Channel Expansion Module.Analog Inputs• 10 differential or 30 single-ended, can be used in any mix.• Relay multiplexer.• Common mode range is dependent on the Datataker model.• Input withstanding voltage is dependent on the Datataker model.• Sensor excitation of 4.5V, 250.0µA, 2.500mA each channel.• Provision for externally-supplied sensor excitation.• Sensor support is dependent on the Datataker model.• Local internal temperature sensor monitors CEM temperature for thermocouple reference junction compensation.Digital ChannelsDigital Inputs• 20 TTL/CMOS-compatible digital inputs for digital state and digital byte (the digital inputs do not count).• Accept voltage-free contact closure inputs.Digital Outputs• 5 normally-open relay outputs, rated to 110VAC/DC at 5A.• 5 open collector outputs, rated to 30VDC @ 200mA.Power Supply• Powered directly from the Datataker power supply.• Enters low power mode (sleeps) when Datataker sleeps.• Current draw 100µA when asleep, 60mA when scanning, 175mA when all output relays activated.Connection to the Datataker• One or two modules can be daisy-chained to a single Datataker.• Interconnection by screened cable, 500mm (20 inches) length• Maximum total cable length 2 metres (6 feet).Mechanical Specification• Robust modular construction using powder-coated steel.• Can be used directly, or housed in fixed or portable enclosures.• Length 270mm (10.5 inches), width 110mm (4.3 inches), height 50mm (2.0 inches), weight 1.0kg.• Signal input/output connection by screw terminals.• Operating temperature –20 to 70 Deg C, humidity 95%.Four standard enclosures are available for housing Datataker data loggers and/or Channel Expansion Modules. Theenclosures are suitable for industrial, weatherproof and portable applications.Industrial Enclosures• The industrial enclosures are constructed of powder-coated sheet steel, have a polyurethane door seal, and are ratedto IP-65 or NEMA 5.• The capacity of each enclosure isSIE - 1 Datataker or 1 CEM.LIE - 1 Datataker plus 1 CEM, or two Datatakers.SIC - 1 Datataker plus 2 CEMs, or three Datatakers.• Each enclosure also houses a 4Ah gel cell or 17Ah alkaline battery.• Panel-Mount Display modules can be factory installed into the door of any enclosure by special order.• Cable entry is completed by the user by drilling holes and fitting cable glands.• Three sizes of industrial enclosures are availableDimensions (mm) Height Width Depth WeightSmall Indust Enclosure (SIE) 400 200 120 4.5kgLarge Indust Enclosure (LIE) 300 380 155 7.0kgSmall Indust Cabinet (SIC) 600 380 210 15.0kgPortable Enclosure• Allows Datataker to be used in a portable mode, and protects the logger from water, dust and mechanical damage.Rated to IP-67 or NEMA 6, and can be submersed for short periods.• Clamshell design, constructed of black ABS plastic with stainless steel hinge. The lid has a neoprene seal, and can bepadlocked.• Withstands 800kg stacking loads, and does not dent or warp.• Houses one Datataker, and a 4Ah gel cell or 17Ah alkaline battery. The logger and battery are mounted into asupporting frame which locates in the base of the enclosure. The frame can be lifted out for easy access to the screwterminals and connectors of the logger.• Optional subassembly to also install a CEM.• A Panel-Mount Display module can be factory installed into the lid of the enclosure by special order.• Normally used with the lid open, however cable for cable entry can be installed by the user.• Size of portable enclosure isDimensions (mm) Length Width Depth WeightPortable Enclosure (PE) 355 260 155 3.5kg

This ROM is mounted insidethe Datataker, on the lower circuit board, and is socketed for easilyreplacement. Please contact your dealer for more information aboutROM upgrades.Note: When operating Datatakers in a network, it is advisable thatall loggers in the network be running the same firmware version.Page 34
