Description

IC660BBA104 6231BP10910
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.
Current Source
Analog In/Out
(115V 50/60 Hz or
125VDC .25A Max)
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)
