HR2B, HR2C High Resolution Interpolators

Product catalog summary

Specifications:
The HR2B and HR2C are high-resolution interpolators designed for use with Gurley Model 9710 and 9717 modular incremental encoders. They require an input power of +5.0 ± 0.25V at a maximum of 125 mA, excluding transmission line termination requirements. The output signals are quadrature square waves with an interpolation factor (INT) of 20, 1, 2, 5, or 10, depending on the model. The maximum input frequency is 25 kHz, while the output frequency varies with the interpolation factor, reaching up to 500 kHz for INT = 20.

Procedures:
The devices include a watchdog circuit that outputs a low signal when analog encoder waveforms are faulty. The output device is an RS-422 differential line driver. The interpolators operate within a temperature range of 0° to 70°C and can be stored between -18° to 71°C. They are designed to handle up to 98% relative humidity in non-condensing conditions.

Norms and Standards:
The HR2B and HR2C are ISO 9001 certified, ensuring quality and reliability in their design and manufacturing processes.

Recommendations:
For optimal performance, it is recommended to consult the encoder data sheet for specific power requirements and to ensure proper termination of transmission lines. The devices are available in different configurations, including PC board assembly for user enclosure or mounted in an aluminum enclosure with IP 40 rating.

Special Capabilities:
Gurley Precision Instruments offers customization options for encoders to meet specific user requirements, such as higher frequency response, greater accuracy, and wider temperature ranges.

Warranty:
A limited warranty is provided against defects in material and workmanship for one year from the date of shipment.
