Product Overview

The Allen-Bradley 1719-IJ is a specialized Frequency Counter module within the Ex I/O platform, precision-engineered by Rockwell Automation. Designed for accurate signal counting and frequency measurement, this 1-channel module is optimized for integration into intrinsically safe systems. It operates on a stable 12V DC supply and is built to withstand industrial rigors, providing reliable performance in temperatures ranging from -20 to 60 °C. Its robust architecture is specifically tailored to minimize the impact of EMI/RFI, ensuring signal integrity in complex electrical environments.

Core Technical Advantages

High-Precision Signal Processing

The 1719-IJ is defined by its exceptional linearity. It provides highly accurate readings across its entire operational frequency range, making it suitable for critical applications such as flow measurement, turbine speed monitoring, and precise pulse counting.

Intrinsically Safe Ex I/O Design

As part of the 1719 series, this module is built for hazardous area connectivity. Its internal resistance of 1 KΩ and 12V DC operating profile are designed to meet the strict energy-limiting requirements of intrinsically safe circuits, allowing for safer deployment in potentially explosive atmospheres.

Industrial Durability

With a total weight of 1.02 kg and a wide operating temperature envelope, the module is built for longevity. It utilizes unshielded wire types with sizes up to 1.5 mm², providing flexible wiring options while maintaining a compact and secure form factor within the I/O chassis.

Installation & Wiring Notes

  • Terminal Torque: Ensure terminal screws are tightened between 0.22 and 0.25 N-m to maintain secure electrical contact without damaging the module connectors.
  • Noise Abatement: While the 1719-IJ is engineered to minimize noise susceptibility, always follow standard industrial wiring practices and separate signal wires from high-voltage AC cables.
  • Hazardous Areas: Verify that the installation complies with all local and international codes for intrinsically safe Ex I/O systems.

Technical FAQs

Q1: What are the primary applications for the 1719-IJ?

A1: It is primarily used for frequency measurement and pulse counting from field devices like flow meters, encoders, or tachometers located in hazardous industrial zones.

Q2: Can I use unshielded wire with this module?

A2: Yes, the module is specified for unshielded wire types; however, using proper wire sizes (0.14 to 1.5 mm²) is critical for meeting safety and performance specifications.

Q3: How does the 1719-IJ handle electrical interference?

A3: The module is designed with a robust input filter and high-quality circuitry to maintain linear, accurate signal processing even in the presence of common electrical noise found on factory floors.
