Product introduction

Triconex The 3511 is a high-performance pulse input module, part of the Triconex

Triconex The 3511 is a high-performance pulse input module, part of the Triconex Safety Instrumented System (SIS). The following is a detailed introduction: - **Product Features** - **Triple Redundant Design**: Utilizing a Triple Module Redundant (TMR) architecture, the module processes inputs through three independent channels and performs majority voting. Even if one channel fails, the module remains operational, making it suitable for critical safety applications with stringent downtime requirements. - **High-Precision Signal Acquisition**: Featuring 16-bit resolution and an accuracy of ±0.01% within the 1000Hz to 20,000Hz frequency range, it precisely measures pulse frequency, enabling reliable speed and position monitoring of rotating machinery such as turbines and compressors. Strong Anti-interference Capability: Featuring AC-coupled differential inputs, the common-mode range is -100V DC to +100V DC peak-to-peak, and the normal-mode range is 1.5V to 200V peak-to-peak. This provides strong noise and interference immunity, enabling stable operation in harsh industrial environments. Hot-swappable: Supporting hot swapping allows maintenance personnel to replace faulty modules without interrupting system operation, reducing downtime and lowering maintenance costs. Multiple Waveform Support: Accepts input signals with various waveforms, including sine, square, and pulse waves, for a wide range of applications. Technical Parameters Input Channels: 8 non-common input channels. Update Rate: Typical value is 25ms. Impedance (Load): Greater than 8kW, typical 20kW. Overrange Protection: Continuous ±150V DC. Hysteresis: Typical 150mV. Duty Cycle: 10% to 90%. Frequency Range: 20Hz to 20,000Hz. Applications: Oil and Gas Industry: Used to monitor pulse signals from turbine flowmeters to accurately measure fluid flow, or monitor compressor speed to ensure proper equipment operation. Power Industry: This system can be used to monitor the speed of generators or the operating status of other rotating equipment, ensuring stable operation of power systems. Chemical Industry: This system can be used to monitor the operating parameters of various rotating equipment during chemical production, and precisely control material flow by processing flowmeter pulse signals.
