ABB Bailey NFBA01 Analog Master Module for INFI 90

This analog master module handles analog signal acquisition and output for INFI 90 systems. It reads sensor inputs and generates control signals for final control elements. The unit mounts in any INFI 90 rack slot for process control.

Technical specifications

Detailed Technical Analysis

This analog master module provides eight analog input channels for sensor monitoring. It accepts voltage or current signals from pressure, temperature, and flow transmitters. The board also offers four analog output channels for valve and damper control. A 12-bit ADC ensures precise conversion for all input signals.

Now let us examine its output capabilities. Each output channel delivers either 0-10V or 4-20mA signals. The module updates outputs every 5 milliseconds for responsive control. Approximately 120 components populate both sides of the circuit board. Fifteen integrated circuits include analog-to-digital and digital-to-analog converters.

This analog module draws 200 milliamps from a 24V DC external supply. Four LEDs show power, run, communication, and fault status. The board contains no batteries or capacitors for energy storage. Eight gold-plated test points allow signal verification during commissioning. The module provides 500V RMS isolation for noise immunity.

Installation and Configuration Guidelines

You insert this module into any available INFI 90 rack slot. Connect the 24V DC power supply to the designated terminals. Wire field devices to the input and output terminal blocks. Select input and output ranges using the jumper blocks on the board.

Configure each channel through the INFI 90 engineering software. The module stores its configuration in non-volatile memory. Verify each input reading and output signal before placing the loop in service. Always power down the rack before inserting or removing this module.

Practical Applications

Engineers use this analog module for INFI 90 system expansion and repair. It handles typical process variables like pressure and temperature. This component also works in legacy DCS retrofit projects. Its 12 channels suit medium-sized process control applications.

Summary of Features

To conclude, this analog module provides 8 inputs and 4 outputs with 12-bit resolution. It weighs 0.45 kilograms and draws 200 milliamps at 24V. Choose ABB Bailey NFBA01 for reliable analog control in INFI 90 systems.
