New GE/Fanuc IC697ALG230F IC697ALG230 ANALOG INPUT

Product Description

IC697ALG230 is a base converter module that can be paired with a current expander module in the GE Series 90-30.The completed analog subsystem includes the base converter and the expander modules; however, the base converter IC697ALG230 has eight differential inputs that are individually configurable for either current or voltage. The base converter accepts either bipolar or unipolar analog inputs of up to 10 volts on the full scale. Additionally, the base converter accepts 4 to 20 milliamp current loop signals as needed. There is also individual user scaling on each input channel on the module. There are no jumpers or DIP switches to configure with this unit, and a fast update rate is common for the base converter. The configuration is easy with either Windows or MS-DOS software functions.

TheIC697ALG230module converts inputs to digital form for the CPU use or for other controllers accessing analog inputs through the VME backplane. All converted data is presented as 2’s complement, and the basic converter is at 14 bits resolution. An oversampling and average technique can further enhance this resolution. All inputs are protected against transient and steady state overvoltage conditions. Percent AI references through the analog inputs are utilized in the programmable controller, though a maximum of 8,000 words of memory is currently available. Each input channel is set to use one word of %AI memory at 16 bits. Configuration is completed through the use of the configuration function of the MS-DOS or Windows software. Additionally, field wiring is made for a removable terminal board. The module is mechanically keyed for correct replacement. I/O references are user-configurable eliminating the need for jumpers or DIP switches.

Note

Previous versions of this power supply had five terminals on the terminal block. The new version (shown above), which has six terminals, is functionally the same as the previous version. The change was made to conform to European EC requirements
