D2000 temperature multiplexer has been designed specifically for temperature measurements in hazardous location; taking full advantage of the low power requirements inherent of temperature measurement. Field units do not require separate power supply nor certified enclosure.
The "D2000 Series" is a multiplexer system specially designed for temperature measurement in hazardous locations. It was developed with the aim of making full use of low power for temperature measurement. The field units installed in hazardous locations do not require explosion-proof certified power supplies. The same system can process both analog (temperature signals) and digital input signals, or a combination of both. Users can build a suitable system for their purposes, achieving significant cost reductions such as in cable installation expenses. 【Features】 ■Reduced foot print: high density, up to 256 channel ■Longer distances: up to 4/5 Km between sensor gateway. ■Higher reliability: certified -40° to + 60° C ■Avoid fault propagation: channel to channel isolation ■Resilience to surges: 500 V isolation ■Faster reaction time: from 0,4 sec for 64 Ch. to 1.6 sec for 256 Ch. ■Faster data collection: 112 KBaud communication speed ■Harsh environment resistance: G3 conformal coating ■Easier troubleshooting: status LED indication *For more details, please download the PDF or feel free to contact us.

basic information
【Other Features】 Multiplexer Advantages [Cost and Installation Savings] When a consistent number of variables is to be collected from a remote location, a simpler solution is to multiplex the signals using master and slave units transferring multiple variables onto the same two wires; this solution eliminates the need for individual wiring, transmitters, IS barriers and analog Input channels. The data is then sent through a single, or redundant, communication line to the gateway placed in safe area. Cable cost saving alone justifies the solution; additional savings are achieved given that 4-20 mA loop instrumentation is no longer required. The result is reduced and simplified wiring, lesser cabinet space and clutter free installation. ■Drastically reduces field wiring & installation costs ■Field units can be placed up to 5 km from gateway ■Eliminates the need of PLC - DCS AI cards ■Installation in Zone 1 without the need of external power source or certified enclosures ■Up to 256 signals per system; Maximum 7.936 ch. ■18 Bits resolution and fast communication speed ■Easy, robust & field proven reliability ■Redundant communication lines to hazardous area (proprietary protocol) ■Redundant communication to PLC/DCS/PC via Modbus RTU System Architecture D2000 Multiplexer accepts both analog and digital inputs in the same system allowing for a variety of potential configurations to fit any application. Configurations with only digital signals or only analog signal or combination of both are possible to suit the best solution in terms of cost and cabling. Following are just some examples of system architecture. Multiplexer: The Only Solution When revamping or expansions in the plant are required, the space for adding cables may be limited or the existing spare cables may be the only ones that can be used. Wireless solutions have several limitations, high implementation costs, and susceptible to cyber security risk. Multiplexing often becomes the only practical solution. Customized Solutions Available Pre-assembled, fully wired and custom engineered field enclosures are available in several configurations, size and materials. Special, custom designed, FISCO cable (CABF008) for connection between field units and gateway is also available. *For more details, please download the PDF or feel free to contact us.
