Current Source Analog I/O blocks are used to interface a controller to devices that provide or accept 4mA to 20mA analog signals. Two

block versions are available:

115 VAC Current-source Analog I/O Block (IC66*BBA104)

24/48 VDC Current-source Analog I/O Block (IC66*BBA024)

These blocks are identical except for the power supply.

Features

Block features include:

•  Six 4-to-20 mA analog circuits: 4 inputs and 2 outputs
•  Isolated channels
•  No user calibration required for operation
•  Software configurable
•  Advanced diagnostics

 Dedicated Bus Switching Module control

A Current Source Analog I/O block has four 4 to 20mA current inputs.  Each input provides a 24 volt current loop power supply and is isolated from all other circuits within the block.  The two output channels provide power and control of two 4-to-20mA current loops. The output channels and BSM circuitry are electrically common, but

isolated from the inputs.

All circuits on the block support independent selection of linear scaling values.  These values can be used to convert the internal

values into engineering units suitable for the application.

Block diagnostics include:

•  input low and high alarm detection
•  overrange and underrange detection for inputs and outputs
•  input open wire detection
•  output feedback error detection
•  internal fault reporting

A dedicated digital output is provided to drive a Bus Switching

Module (version IC66*BSM021 only).
