ITC-7X-STX: Isolated Strain Gauge Signal Conditioner/Converter
Function:
The ITC-7X-STX provides high isolation from Input to Output to Power in a small, easy to
install package. The universal DIN rail mount often makes it possible to install the ITC-7X-STX
right next to other instruments that it is to be wired to. The many different input and output
configurations allow it to be used in a great variety of Strain Gauge applications ranging from
PLC front end conditioning to stand-alone operation of weight scales.
The high output drive (1000 Ohms @ 4-20 mA) allows the ITC-7X-STX to drive several other instruments
directly from its output.
Any standard Strain Gauge that has a minimum resistance of 100 ohms may be used. Standard input
ranges are readily available and custom ranges are available upon request.
