Triconex 3515 Pulse Accumulator Input Module

• System Affiliation: The Triconex 3515 Pulse Accumulator Input Module is a member of the Invensys Triconex product series, which is a modern fault-tolerant controller based on the Triple Modular Redundancy (TMR) structure.
• Power Requirements: The operating voltage is 24VDC.
• Channel Isolation: Channels are isolated from each other, so a single point of failure in any channel cannot be transmitted to another channel.

• Pulse Accumulation Function: It is mainly used to accumulate and count input pulse signals, and can be widely applied in occasions that require accurate measurement and statistics of pulse signals, such as product counting in production lines and logistics package quantity counting.
• Photoelectric Isolation Technology: It adopts the photoelectric isolation method, which can effectively isolate external interference signals, improve the anti-interference ability of the module, and ensure the accuracy and stability of input signals.
• High Reliability: Based on Triconex’s Triple Modular Redundancy (TMR) architecture, it integrates three isolated parallel control systems in one control system. Each channel independently executes the control program in parallel with the other two channels, and uses two-out-of-three voting to provide high-integrity, error-free, and uninterrupted process operations without single-point failures.
• Online Replacement: When the controller is online, if the module fails, it can be easily disassembled and replaced without interrupting the process, which facilitates the maintenance and upgrading of the system.
• Extensive Diagnostic Functions: Each channel, module, and functional circuit has extensive diagnostic functions, which can immediately detect and report operational faults through indicator lights or alarms, making it easy to identify and solve problems in a timely manner.

• Industrial Automation Production Lines: It is used to count products on the production line, monitor the production quantity in real-time, so as to carry out production scheduling and quality control. For example, in the automobile manufacturing production line, it can count the number of assembled cars.
• Logistics and Warehouse Management: It counts the goods entering and leaving the warehouse to realize accurate inventory management. For instance, in e-commerce warehouses, it can count the number of incoming and outgoing goods, providing data support for inventory checking and replenishment.
• Process Control Systems: In the process control systems of chemical, petroleum, electric power and other industries, it measures and accumulates various pulse signals, such as pulse signals output by flow sensors, which are used to calculate the cumulative flow of materials.
• Mechanical Equipment Monitoring: It monitors the operating parameters of mechanical equipment, such as the rotation speed of motors and the number of revolutions of shafts. Through the accumulation and analysis of pulse signals, it realizes the monitoring of equipment operating status and fault diagnosis.
