Cable Length Capabilities with External Power

When external power is provided, the 1771-HTE supports cable runs up to 90 feet for various encoder types. This includes +5V DC encoders, +15V DC encoders, and resolvers. This extended length offers greater flexibility for large system layouts.

Cable Length Without External Power

In configurations without external power, the module limits cable distance. It supports a maximum cable length of 40 feet specifically for +5V DC encoders. This ensures reliable signal transmission even in power-limited scenarios.

Installation and Mounting Details

The physical design of the Allen-Bradley 1771-HTE facilitates easy integration. Its dimensions are 6.25 x 3 inches (15.8 cm x 7.5 cm). This compact footprint allows it to fit into densely packed control panels.

DIN-Type Rail Mounting

The module installs quickly using the built-in DIN-type rail mechanism. This method secures the unit firmly and simplifies the installation process. Furthermore, it allows for easy removal during maintenance activities.

Cable Management and Connectivity

All field wiring connects to the module via pluggable connectors. This design reduces wiring errors and speeds up installation. Additionally, all user connections are conveniently routed through termination panels for an organized setup.

Environmental and Mechanical Characteristics

This termination module is built for industrial environments. It adheres to Allen-Bradley's rigorous quality standards for the PLC 5 series. Its robust construction ensures reliable performance in typical factory floor conditions. Meanwhile, the unit's design minimizes electromagnetic interference from other equipment.
