IC697ALG230

The IC697ALG230 is a base converter module from the Series 90-70 Programmable Logic Controller (PLC) platform that is formerly manufactured by GE Fanuc Automation, currently under Emerson Automation. This module is part of a high-level analog system that comes with Eight (8) differential inputs individually configurable for voltage or current signals particularly, 4-20 mA current output signal and -10VDC / +10 VDC voltage output signals with a channel resolution of 16-bits. The IC697ALG230 supports the installation of expander modules with catalog numbers IC697ALG440 Voltage Expander Module and IC697ALG441Current expander modules. These expander modules enhance the capability of the base converter module, enabling the accommodation of up to Sixteen (16) channels of the same signal types. The IC697ALG230 base converter module has a built-in Analog-Digital Converter (ADC) circuit that converts the received digital data to analog equivalent with a resolution of 14-bits. Individual low pass filters are installed to each of the module’s channels as well as an opto-isolation circuit that provides module isolation to the PLC backplane. The IC697ALG230 supports differential wiring configuration. With differential wiring, the input signal is measured by the difference of Two (2) reference wires. This configuration has greater resistance against Electromagnetic Interference (EMI) and is most applicable in critical systems where accurate measurement is a consistent necessity. The base converter module comes with Forty (40) terminals. These terminals are mounted to a removable base which can be easily removed by a jackscrew driver. A door insert is provided to the module allowing users to write input short descriptions for easy identification.

The GE Fanuc IC697ALG230 Base Converter Module is designed to be used with GE Series 90-70 expander modules in a high-level analog input system. It comes with 8 differential inputs that can be configured for voltage or current individually. It also offers individual user scaling for each channel. The IC697ALG230 Base Converter Module has 2.4 milliseconds to 2.8 milliseconds of fast update rate times. It has an expansion port that is used to connect the voltage or current expander module. In order to increase the number of inputs, the module is capable of handling up to 7 expander modules. The IC697ALG230 Base Converter Module uses an efficient input sampling technique with a fast update rate. It also has a serial communication port that can be used to control the expanders via the processor of the base converter module. After connecting the maximum number of expander modules, the system can have a maximum of 120 inputs. There is a removable 40-terminal connector block on the front face of the module which can be used to connect user devices. The analog-to-digital converter of the IC697ALG230 Base Converter Module connects with the analog inputs of the expander module through a switching circuit. It has CPU alarm interrupts and CPU fault reporting facilities on a per-channel basis. Its MS-DOS Windows configuration software provides the facilities to program each input according to the needs of an application. The configuration software package also offers the data commands needed to modify some of the configuration parameters of the base converter module with the ladder logic.
