Weight controller LCA-D Aluminum case
Weighing terminals and amplifiers of the LCA-D model are intended for use in weighing systems with the possibility of remote control and information reading. Indicator information can be read both directly from the terminal display and from a remotely connected computer. The main capability of the LCA-D controller is control using the Modbus protocol. Using the Modbus protocol, remote control of all software parameters and reading of all terminal readings is possible. Also, using the Modbus protocol, it is possible to simultaneously control several terminals connected to one communication line. Thus, it becomes possible to solve tasks using a set of terminals controlled by a computer or PLC. Two programs for the Windows ™ operating system were developed to control and connect the terminal to a computer. The first (DLMS_VP) enables control and communication with only one device, the second (DLMS_NW) enables communication with several devices and with devices connected to another computer in the local network. The body of the controller is made of cast aluminum and is completely protected against dust and moisture, as well as resistant to corrosion.
