Overview

The Triconex PI2381 7400221-100 Pulse Input Baseplate is a critical component in Triconex’s triple modular redundant (TMR) architecture. It provides the physical and electrical foundation for PI2381 pulse input modules, which monitor and process high-speed pulse signals from field devices such as flow meters, encoders, and turbine sensors.

Moreover, this baseplate ensures stable signal transmission, robust electrical isolation, and efficient thermal management. Its rugged construction and compact form factor make it suitable for harsh industrial environments where uptime and fault tolerance are essential.

For instance, in a refinery’s flow monitoring system, the PI2381 baseplate supports pulse input modules that capture turbine meter signals, enabling accurate flow measurement and real-time diagnostics.

Technical Data

Typical Applications

• Flow Measurement Systems: Interfaces with turbine and magnetic flow meters for pulse signal acquisition.

• Rotational Speed Monitoring: Captures encoder pulses for motor and turbine diagnostics.

• Safety Instrumented Systems (SIS): Supports fault-tolerant pulse input processing in emergency shutdown systems.

• Power Generation Facilities: Monitors pulse signals from auxiliary systems and rotating equipment.

• Chemical and Refining Plants: Enables accurate flow and speed monitoring in hazardous process environments.

The PI2381 baseplate is also commonly used in retrofit projects, upgrading legacy pulse input systems to modern safety standards.
