Ovation 1C31147G31 Pulse Accumulator Module

Product Introduction

The Ovation 1C31147G31 Pulse Accumulator Module is a high-performance input module specifically designed for precise counting and integration of high-speed pulse signals in Ovation™ distributed control systems. It captures pulses from flowmeters, turbine meters, and other frequency-based sensors, converting them into accurate, real-time data for process control and monitoring. With robust isolation, a wide input frequency range, and built-in diagnostics, the 1C31147G31 ensures dependable operation in critical industrial environments where reliability and precision are essential.

Product Parameters

Applications

• Flow Measurement – Integrates with turbine and magnetic flowmeters for accurate totalization of liquid or gas flow.

• Energy Metering – Captures pulses from electrical energy meters to calculate total power consumption.

• Batch Processing – Accumulates pulses from filling or dosing equipment for precise quantity control.

• Turbine Monitoring – Tracks rotational speed and output from turbine sensors in power generation plants.

• Water & Wastewater – Measures totalized flow in treatment plants and pumping stations.

• Industrial Automation – Counts events or machine cycles in packaging, printing, and material-handling systems.

Advantages

• High-Speed Counting – Handles input frequencies up to 25 kHz for rapid pulse accumulation.

• Four Isolated Channels – Allows simultaneous measurement of multiple independent pulse sources.

• Accurate 32-bit Resolution – Ensures precise counting over long operating periods without overflow.

• Robust Electrical Isolation – 1500 V RMS isolation protects control electronics from noise and ground faults.

• Redundant Communication – Dual Ovation™ I/O bus guarantees reliable data transfer to the controller.

• Hot-Swappable – Can be replaced without shutting down the control system, minimizing downtime.

• Wide Environmental Range – Operates reliably under extreme temperatures and high humidity.

• Comprehensive Diagnostics – Built-in self-tests provide early detection of signal or hardware issues.
