The Allen Bradley 1797-TPR serves as a right-angle T-Tap intended for efficient integration into ControlNet Ex networks. It accepts 75 Ω coaxial connections and is compatible with a variety of FLEX Ex accessories, enhancing its versatility in mission-critical installations. The device mandates a 75 Ω termination on the coax trunk to ensure signal integrity.
Engineered to cater to industrial applications, this T-Tap features a right-angle configuration that minimizes space consumption within panels. It is generally installed as a branch connection from the main coax trunk cable in ControlNet architectures, facilitating the addition of a single node.
Construction of the 1797-TPR accommodates operational settings in environments rated for -20 to 70 °C. It primarily serves indoor applications and requires careful grounding, specifically equipotential bonding, for areas classified as hazardous. This module is designed for use in spaces devoid of corrosive gases, ensuring longevity and reliability in industrial conditions.
For cable connections, RG-6 quad-shield coax is recommended as the trunk cable, contributing to robust performance when paired with this T-Tap. Its compatibility with hazardous location ratings makes it a reliable choice for both Zone and Division installations when deployed alongside properly certified equipment.
