Load Cell Transmitter
MODEL SST-HV
-
The SST-HV 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-HV 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-HV may be powered from 95-240 Vac ±10%. 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.

CAS Modbus Scanner
-
CAS Modbus Scanner is a utility to retrieve coils, inputs, holding registers, and input registers from a Modbus enabled device. Values retrieved from the device can be viewed in many different formats including Binary, HEX, Uint16, Int16, Uint32, Int32, and Float32. This utility can also discover Modbus devices on your network if you do not know their address. It works by testing every address, function, length, offset to check for exceptions or responses.
