Description

ABB TC512V1 3BSE018059R1 Twisted Pair Modem

The NI 9361 is a high-performance, 8-channel counter input module designed for the CompactDAQ and CompactRIO platforms. It is widely used for measuring frequency, pulse width, and encoder signals in demanding industrial and research environments.

## Product Overview

The NI 9361 is a versatile differential counter module that provides a bridge between industrial sensors (like encoders, flow meters, and tachometers) and your data acquisition system. Its primary strength lies in its high-speed sampling and its ability to handle a wide range of signal types and voltage levels.

## Key Specifications (Parameters)

## Product Advantages

• Synchronized Measurements: Unlike standard counters, the NI 9361 can synchronize counter data with other analog or digital modules in the same chassis, ensuring perfectly aligned time-series data.

• Flexible Signal Routing: It supports a variety of sensor types, including encoders with index pulses and flow sensors with high-frequency outputs.

• Integrated Debounce Filters: Features programmable digital filters to eliminate mechanical switch bounce or high-frequency noise from your input signals.

• High Dynamic Range: With its 32-bit resolution, it can track very large counts or high frequencies without overflowing quickly.

• Rugged Design: Built to withstand harsh environments with a wide temperature range and high vibration/shock resistance.

## Important Considerations (Usage Notes)

1. Terminal Wiring: Ensure correct wiring for differential vs. single-ended signals. Differential signals (RS-422) offer much better noise immunity over long cable runs.

2. Power Supply: While the module is powered by the chassis, ensure your sensors are powered correctly, as the NI 9361 does not provide excitation voltage to external sensors.

3. Isolation Limits: While the module features 250 Vrms bank isolation, it does not have channel-to-channel isolation. All channels share a common ground reference within the module.

4. Software Requirements: Requires NI-DAQmx (for CDAQ) or NI-RIO (for CRIO) drivers. Ensure your software version supports the module revision.

## Common Applications

• Rotational Monitoring: Measuring RPM and position using quadrature encoders on motors or turbines.

• Flow Measurement: Interfacing with turbine flow meters that output a frequency proportional to the flow rate.

• Velocity Tracking: Used in automotive testing to track wheel speed or vehicle velocity.

• Pulse Width Modulation (PWM) Analysis: Measuring the duty cycle and frequency of control signals.

• Event Counting: High-speed counting for production lines or particle detection.
