DISOCONT® Measurement, Control and Supervisory System % Field housing electronics integration able into scale mechanics % New product line for ‘MechaTronic scales’ a synthesis of mechanics, electrics and software % Reduced engineering planning and wiring costs % Optimal communication structures because of modular fieldbus technology Application DISOCONT® is a modular electronics system applicable to any weighing and feeding system. It is used wherever bulk solids flow has to be measured, feeded or batched with the use of % Loss-in-weight feeders (measur-ing/feeding) % Weighfeeders % Mass flow meters and feeders % Solids flow meters and feeders % Belt weighers % Weighing hoppers The DISOCONT® electronics are prefer-rably integrated locally into the scale mechanics. So self-contained function units will be created - the MechaTronic scales - which offers numerous advan-tages: % Reduced engineering because of minimal number of interfaces; only one unit has to be planned in % No control cubicle % Reduced cabling; only power and data cables have to be run % At a glance - easy service because of the combination of mechanics and electronics DISOCONT® electronics may be conven-tionally installed in a control cubicle (e.g. for use with feeders in hazardous zones). The DISOCONT® equipped with appro-priate communication module optimally integrates into the automation structure via field bus. Equipment The DISOCONT® electronics consist of a system unit and multiple optional expan-sion units. Its modular design enables the requisite units to be combined for a spe-cific application, at a most cost effective price. % System unit for all measuring and control functions; equipped with service plug for connection of laptop or control unit, for configuration, calibration and service with an exchangeable memory module for system specific settings and operat-ing values % Fieldbus communication modules plugged into system unit for transfer of all relevant data to the user’s control and scale control system % Input/output unit for conventional connection to user’s control system and expanded control of the scale environment % EasyServe - PC-program for commissioning and service % Operator panel with clear graphic text display for local scale control and/or parametrization of standard applications. % Group control unit- operation, survey and control of scale groups, as shown in separate spec sheet The internal DISOCONT® communication bus permits a flexible arrangement of the I/O units, locally or in cabinets. All modules can be replaced with no need for recalibration and reconfiguration (Plug & Play). The program includes housing options for installation at site and in control cubicles. BV-D2051GB
