National Instruments 777318-500 High-Speed Counter Module

Part number 777318-500 from National Instruments is the identifying part number for the cFP-CTR-500 High-Speed Counter Module. The 777318-500 is a highly adaptable high-speed counter module created for industrial and scientific applications that require accurate counting and timing. This module provides 8 counter inputs, each having a 16 bit resolution that can cascade up to a 128 bit resolution. The 777318-500 versatility makes it suitable for a variety of applications including simple event counting to complex measurements at high speeds. The module eatures a maximum isolation voltage of 250 Volts rms with no isolation between channels, thus with this, it can protect the module from potential damage.

Counter inputs for the 777318-500 are built to handle voltages from 10 through 30 Volts DC, and they are sinking input types. Additionally, this module includes 4 gate entries supporting maximum frequencies up to 50 kHz. Input current is limited at 5 mA thus ensuring its efficient operation as well as safe operation in these conditions. In terms of output, this device features 4 channels each capable of sourcing between 10 through 30 Volts DC allowing it to interface with different devices or systems within industrial automation or process control environments.

This model operates at ambient temperatures of -40 to +60 degrees Celsius making it robust enough for harsh environments. It is capable of being stored in temperatures ranging from -55 to +85 degrees Celsius with a relative humidity level ranging from 10% to 90 %, non-condensing. This high-speed counter module is both small and light weighing just 100 grams with dimensions of 10.7 cm by 10.9 cm by 9.1 cm only but still very compact and portable.

The high-speed 777318-500 is designed to withstand operating vibrations of 10 to 500 Hertz, 5 grams which are random under the (IEC 60068-2-64) standard while operating vibrations of 10 to 500 Hz, 5 g that is sinusoidal under the (IEC 60068-2-6) standard and operating shocks of 50 g, 3 ms half-sine,18 shocks at 6 orientations, 30 g, 11 ms half-sine, 18 shocks at 6 orientations.
