Normalizing amplifier – LCA X amplifier
Amplifiers and weighing terminals of the LCA-X model are mainly used in weighing systems that have the possibility of remote control and reading of information from a remote PC, since the device does not have a display.
Control using the Modbus protocol is the main advantage of the amplifier. The use of this protocol allows you to read all weighing data and manage all software parameters. It is possible to control several terminals at once if they are connected to one communication line.
Programs for the Windows ™ OS were developed specifically for the connection between the computer and the terminal. One of them, DLMS_VP, is designed to connect a PC with only one device and control it, the other – DLMS_NW, can connect a PC with several devices at the same time, as well as with devices connected to another PC located in the local network.
The body is completely wet and dustproof, resistant to corrosion, the material is cast aluminum.
Features of the LCA X amplifier:
- Dust- and moisture-proof housing made of cast aluminum
- Tare input in the entire weighing range
- Determination of the output range according to the connected sensors
- Digital linearization
- Digital temperature compensation
- Remote control of all parameters (Modbus)
- DLMS_VP program for communication with one device
- Serial port RS232 / RS485>
