GK409 is a highly precise, modular and high-speed A/D conversion device concerting the output signal of a resistance strain sensor into a digital signal with a unit of mV/V. It is mainly used as a part for electric signal measurement and digital conversion in various weighing scales, force (such as tensile force, pressure, shear and torque) testing equipment and automatic pressure control equipment.

The product has a supply voltage of DC24V and provides 5V/60mA sensor excitation power supply and a reference voltage input end. The measurement signal input is a differential input. It provides continuous data latching function and configurable moving average digital filters for easy application.

View times:
● Designed for widely used resistance strain bridges, mainly used in devices in which resistance strain sensors are used as primary elements.
● With a digital output of unit of mV/V, which is the same as resistance strain sensor. Realize no-real-object calibration for systems.
● High accuracy interchangeability because of internal highly precise and high speed A/D conversion circuit, based on ratio measurement principle.
● With multiple digital filters
● Configure operating parameters through the read and write operations of register to choose the most appropriate performance.
● Configure readout instructions for kinds of measurement data for higher communication efficiency.
● With a standard guide rail type horizontal module housing for easy installation in electric control cabinet
