The Allen-Bradley 1771-HT is a Termination Panel Module engineered for the PLC 5 product line. This module serves as a simple controller interface specifically intended for use with IMC 12X series motion controllers. One termination panel is required for each servo controller module (SCM) when wiring the E-Stop string, feedback devices, drives, and fast inputs and outputs. Furthermore, the 1771-HT offers a convenient solution for connecting and troubleshooting IMC 120 systems. Its onboard D-shell connectors and pluggable screw-type terminals simplify field wiring and maintenance.
This section details the core technical capabilities of the 1771-HT module.
The 1771-HT provides fast I/O capabilities for motion control applications. Specifically, it features 4 fast inputs, labeled FI1 through FI4, and 4 fast outputs, labeled FO1 through FO4. Status LEDs on the board indicate the real-time state of these I/O points, simplifying troubleshooting. Additionally, the module includes an onboard socketed relay for E-Stop functions. This relay provides contacts that allow you to daisy-chain connect up to 3 servo controllers onto a single E-Stop string. Consequently, the 1771-HT streamlines safety wiring in multi-axis systems.
Inputs: 4 Fast Inputs (FI1-FI4)
Outputs: 4 Fast Outputs (FO1-FO4)
Indicators: I/O LED status indicators
Relay: Socketed onboard E-Stop relay
The 1771-HT offers flexible connection options for various system components. It features D-shell connectors for cables from the servo controller and resolver excitation modules. Additionally, pluggable screw-type connectors are provided for wiring to user devices. Separate pluggable connectors are available for encoders and resolvers, enabling you to use the termination panel in either resolver or encoder systems. Moreover, an RS-232 communication port is provided for serial connectivity. Therefore, the 1771-HT accommodates a wide range of field devices and system configurations.
Connector Type: D-shell, Pluggable Screw-type
Communication: RS-232
Connection Type: Onboard connections
The 1771-HT serves as a central wiring hub for the IMC 12X motion control system. When using this termination panel option, all user connections except for the RS-232 communication port and the user-side power are routed through the panel. This centralized wiring approach simplifies installation and reduces wiring errors. Furthermore, all connections are clearly designated on the board, facilitating easy identification during setup and troubleshooting. The 1771-HT also supports daisy-chaining of E-Stop strings across multiple servo controllers, enhancing system safety and reducing wiring complexity.
The 1771-HT incorporates essential safety features for motion control systems. Its onboard E-Stop relay provides reliable emergency stop functionality. Specifically, the relay contacts allow you to integrate the module into a safety circuit that can shut down drives when an emergency condition occurs. Furthermore, you can daisy-chain up to 3 servo controllers onto one E-Stop string using the relay contacts. This feature simplifies safety wiring in multi-axis systems while maintaining compliance with safety standards. Therefore, the 1771-HT contributes to a safer and more manageable control architecture.
The 1771-HT is specifically designed for the PLC 5 platform and IMC 12X series motion controllers. It interfaces seamlessly with servo controller modules (SCMs) and resolver excitation modules. Furthermore, the module supports both resolver and encoder feedback systems, offering flexibility for different motion control applications. The 1771-HT is part of a comprehensive PLC 5 system that supports various communication networks. This integration capability allows you to incorporate the 1771-HT into larger plant-wide automation architectures.
The 1771-HT is built for reliable operation in industrial environments. Its design ensures compatibility with standard PLC 5 chassis and mounting requirements.
Dimensions: Standard PLC 5 form factor
Operating Temperature: 32 to 140 °F (0 to 60 °C)
Relative Humidity: 5 to 95% (non-condensing)
Proper installation of the 1771-HT ensures reliable system operation. First, mount the termination panel in a suitable location near the servo controller. Next, connect the D-shell cables from the servo controller and resolver excitation modules to the appropriate ports. Then, wire your field devices to the pluggable screw-type connectors according to the designated labels. After wiring, install the E-Stop relay into its socket. Finally, connect the RS-232 communication port and user-side power as required. Additionally, always power down the system before installation or maintenance to protect personnel and equipment.
