Description
Product Name: 1771-OF04 Allen Bradley Programmable controller
Product details:
The 1771-PM is a microprocessor-based module essential for building a clutch/brake controller and press system that operates with a PLC Programmable Controller using 1771 Remote I/O Operation.
- Function: It is primarily used for monitoring and controlling a mechanical power press using a standard algorithm.
- Capacity: It can connect to up to 4 operator stations.
- Operation: It monitors operator inputs, monitors the shaft position via cam limit switch feedback, and controls the press using solenoid triac outputs.
- Redundancy: To provide press control from the remote I/O chassis, two of these modules, operating in parallel, are typically required for safety and redundant control.
- Diagnostics: It generates three types of 8-bit binary fault codes, including trip-condition, latched, and non-latched messages, for troubleshooting.

✨ Product Advantages (产品优势)
- Dedicated Control: Provides a specialized, high-reliability solution for critical press control and clutch/brake applications.
- Safety Features: Designed with press control in mind, often requiring parallel operation for redundancy and featuring fault code generation for rapid diagnostics and trips.
- Flexibility: Offers flexibility in selecting clutch/brake controller functions via switches on the I/O chassis, allowing for application-specific configuration.
- Integration: Seamlessly integrates with the established Allen-Bradley PLC-5 platform and 1771 Remote I/O system.
⚠️ Precautions (注意事项)
- Parallel Operation: For true press control, two 1771-PM modules operating in parallel are typically required for safety and redundancy in the remote I/O chassis.
- Configuration: The switches on the I/O chassis must be set correctly according to the specific application requirements.
- Environmental Protection: Follow standard industrial control practices, such as grouping analog and low-voltage DC modules away from AC or high-voltage DC modules to minimize electrical noise interference.
- Power Supply: Ensure the 1771 I/O chassis power supply meets the current draw requirements of the 1771-PM and all other installed modules.
- Discontinued Status: The 1771-PM is a legacy product and has been discontinued by the manufacturer. New installations should consider modern safety PLCs/components, and spare parts may only be available from third-party industrial suppliers.
🏭 Product Applications (产品应用)
The Allen-Bradley 1771-PM module is primarily used in:
- Mechanical Power Press Control: Its core application is to manage the clutch and brake mechanism of mechanical presses, ensuring proper and safe operation cycles.
- Metal Forming and Stamping: Used in industrial settings where stamping, blanking, or other metal forming operations are performed using press machines.
- High-Speed/High-Volume Manufacturing: Applications requiring precise, repetitive control of a clutch/brake mechanism.
