Load Cell Transmitter
MODEL SST-LV
-
The SST-LV is a Plug & Play Smart TEDS IEEE 1451.4 compliant Transmitter. Just plug in a TEDS compatible Load Cell or Torque Sensor and the SST-LV will automatically self-calibrate. When used with a non-TEDS Load Cell or Torque Sensor, the SST-LV Transmitter is easily programmed using a PC with an RS232 port and Instrument Setup (IS) software, which provides a graphical user interface. The SST-LV may be powered from 12-30 Vac or 10-48 Vdc. The SST-HV Has an Isolated transducer excitation output that is selectable between 5Vdc or 10Vdc. There are Dual solid state relays and an Isolated 4-20 mA, 0-20 mA or 0-10V analog output. There are three Isolated serial data transmitter output ( RS232 , Half-duplex RS485, full-duplex RS485 ) and three serial protocols that are software selectable (Modbus RTU, Modbus ASCII and Custom ASCII). Isolation to 250V rms is provided for power, signal input, analog output, relay outputs, and communications. Isolation adds safety and avoids possible ground loops. The transducer excitation output is isolated to 50V from signal ground.
