Key Product Details and Functions
Intelligent I/O Board:The P144.R4 is more than just a simple I/O card;it’s an”intelligent”board.This means it has its own local processing capabilities,offloading tasks from the main CPU of the FloBoss S600/S600+.It handles the conversion of inputs and outputs between engineering units and field values and can run background tests and PID(Proportional-Integral-Derivative)loops directly.
Core I/O for FloBoss S600/S600+:This board is supplied as a standard component with the FloBoss S600+and is typically the primary I/O module in both S600 and S600+systems.It provides a versatile mix of input and output types:
Analog Inputs:Accepts analog signals(e.g.,4-20 mA from pressure or temperature transmitters)to measure physical quantities.
Digital Inputs:Receives on/off signals from switches,relays,and other binary devices.
Digital Outputs:Provides on/off signals to control actuators,relays,or indicators.
Pulse Inputs:Specifically designed to receive pulse signals from various flow meters(e.g.,turbine meters,positive displacement meters).The S600+is typically supplied with a P144 module that includes a Pulse Mezzanine(P148)module as a daughterboard,which enhances its pulse input capabilities.
Measurement and Control:It’s essential for the FloBoss S600’s functions,enabling it to:
Perform fiscal flow measurement by collecting accurate data from flow meters and other sensors.
Support multi-stream and multi-station applications for both liquid and gas.
Execute PID control for flow balancing and scheduling.
“R4″Designation:The”R4″indicates a revision or version of the board.This suggests that it’s an updated version incorporating enhancements or changes from previous revisions(e.g.,R1,R2,R3).These revisions often include improved stability,new features,or component updates.
Distributed Processing:As mentioned,the intelligent nature of the P144.R4 contributes to the FloBoss S600’s distributed processing architecture,which maximizes overall system performance by distributing computational load.
Robust Industrial Design:As a component of a critical industrial flow computer,the P144.R4 is built with robust components to withstand the harsh conditions of industrial environments,ensuring high reliability and long-term stability.
