DISOMAT® Satus Weighing Transmitter % Digital Weighing Transmitter % Level Control % Single-Component Feed Control System % System-Compatible with Fieldbus, Serial Interface, Analog Output and Binary Inputs and Outputs % Ethernet Connection % Comfortable commissioning with the DISOPLAN Program % Four 230 V Relay Outputs % Three Binary Inputs % Optional Weight Display Model Designed for Connecting Scales in Hazardous Areas Application The DISOMAT® Satus weighing transmitter is a reasonably priced solution for many basic weighing tasks. Its fieldbus, serial interface and analog output make it suitable for scales not operated on-site which are connected to higher-order electronic data processing and PLC systems. The optional display also allows on-site monitoring of weight values. Typical Applications for the DISOMAT® Satus are: - Weight sensor for weight control and bin level measurement. Serial or analog transmission of data to an electronic data processing or PLC system - Monitoring of containers' fill levels, indicating MIN and MAX values via parallel contacts - Single-component feed process (GIW or LIW operation). Design The VSE 20900 basic board comprises the following functions: % Measuring circuit with A/D conversion % 4 relay outputs safety separated % 3 binary inputs, galvanically free % 1 analog output % 3 serial interfaces % Ethernet connection (10/100Mbaud) % Extension connector for fieldbus module (Profibus / DeviceNet / Ethernet IP) The following functions can be executed using expansion cards: • PROFIBUS coupling • DeviceNet coupling • Display, 3 1/2 digits, 10 mm digit height, for weight monitoring. • 3 push-buttons for controlling scales functions The basic board is slotted into a 19" sub-rack as a plug-in board. The device is powered either by 24 VDC or by optional 115 / 230 VAC power supply modules. Weighing sensors and display devices in category 2G (zone 1) are connected using the optional barrier sets. The barrier sets are inserted directly into the 19" slots. Alternatively, the DISOMAT® Satus may come fitted in a field housing. This version also comes with the option of 24V power supply and integrated power supply unit. The field housing comes in designs suitable for direct on-site assembly in potentially hazardous areas of the category 2D / 3G. BV-D2256 GB

Communication With up to three serial interfaces, the DISOMAT® Satus is fully equipped to exchange data with its environment. For example, - Configuration - Serial display - Data Processing may be connected in parallel. Two of the interfaces are RS-232 interfaces. The third (RS-485, 2/4-wired) is specially suited to communication within the bus and over longer distances. In control systems the Ethernet connector (10/100 MBaud) is operated using the MODBUS/TCP protocol. Alternatively, HTML pages stored in the device may be called up using a standard web browser. The device can also be...
