FloBoss S600+ P144 I/O Board 7281440
Product Code: 7281440
The P144 I/O Board is the primary input/output module for the FloBoss S600+ Flow Computer, provided as standard with the base unit. This versatile module is designed to interface with a wide range of field instrumentation, converting analog and digital signals into engineering units for processing by the CPU. Its comprehensive connectivity makes it suitable for various flow measurement and control applications.
The module features a robust set of I/O points, including analog inputs, analog outputs, digital inputs, and digital outputs. The analog inputs are highly accurate, utilizing a 24-bit auto-zero, auto-calibrate A/D converter. They support various signal types, including 1 to 5 V, 0 to 5 V, 4 to 20 mA, or 0 to 20 mA, providing flexibility for connecting pressure transmitters, temperature sensors, and other field devices.
Detailed I/O Specifications
Analog Inputs: 12 channels (opto-isolated). Voltage inputs offer an accuracy of ±0.005% of FSD at 23°C, while current inputs offer ±0.02% of FSD.
Analog Outputs: 4 channels (4 to 20 mA, opto-isolated). 12-bit resolution with an accuracy of ±0.1% at 23°C.
Digital Inputs: 16 opto-isolated inputs (arranged in 4 groups of 4) for status monitoring.
Digital Outputs: 12 opto-isolated open-collector outputs (3 groups of 4) for control applications.
PRT (RTD) Inputs: 3 channels for 4-wire Pt 100 transducers, offering high-accuracy temperature measurement.
The P144 board also provides connections for frequency/density inputs and pulse outputs, enhancing its capability for flow meter integration. It includes a dedicated raw pulse output for proving applications, supporting frequencies up to 10 kHz. This level of integration reduces the need for additional signal conditioning equipment, simplifying system design and reducing installation costs.
Each I/O point is opto-isolated to protect the CPU from electrical noise and voltage spikes common in industrial environments. The board's design ensures reliable operation even in harsh conditions, with continuous background checks performed locally to assure operational validity. This makes the P144 an ideal choice for critical fiscal measurement installations where data integrity and system reliability are paramount.
