Product Procurement & Buyer Guide
Core Specifications for Selection
The 1771-HSARS operates with a 120 Volt fuse voltage rating. This module uses a 250 Kilohertz differential maximum input frequency. It delivers a +/- 10 Volt DC analog command output for precise servo control. Its update period is only 2 ms per axis.
Advanced Control Capabilities
This module includes an advanced ratioing capability for complex motion profiles. It contains a standard 1771-HMA plug-in memory cartridge. This setup simplifies programming and machine parameter storage. The 1771-HSARS supports large regulatory and sequential control applications.

Installation Requirements and Compatibility
You need only one chassis slot for installation. The backplane current load is just 1.7 Amperes. This module works seamlessly with PLC 5 controllers. It uses networks like DH+, ControlNet, and EtherNet/IP for communication.
Physical Dimensions and Environment
The 1771-HSARS measures 3.5 x 6.5 x 2.0 inches. Its weight is only 2.2 pounds. This module operates in temperatures from 0 to 60 degrees Celsius. It handles 5 to 95 percent noncondensing relative humidity.
Step-by-Step User & Installation Guide
Step 1: Chassis and Slot Preparation

Ensure your Bulletin 1771 I/O chassis has a free slot. Power down the entire chassis before beginning installation. Ground yourself to prevent electrostatic discharge damage. Verify the slot is clean and free of debris.
Step 2: Module Insertion and Mounting
Align the 1771-HSARS module with the chassis backplane connectors. Slide the module firmly into the single slot. Secure it using the top and bottom locking tabs. Check for a snug and stable fit within the rack.
Step 3: Wiring Arm Connection for I/O
Connect the provided 1771-WA wiring arm to the module. Secure the wiring arm by tightening its retaining screws. This arm allows module replacement without disconnecting field wiring. Ensure all connections are tight and properly seated.

Step 4: Power-Up and Initial Configuration
Apply power to the 1771 I/O chassis. Monitor the module’s status indicators for correct startup. Configure the module’s parameters through your PLC 5 programming software. Set the fuse voltage rating for proper circuit protection.
