The GE Fanuc series 90-30 programmable logic controller (PLC) module (catalog number IC693ALG223) is a sixteen (16) channel, single ended analog input module used to connect field devices and instruments that provide analog signals to represent measured values of process variables. Specifically, each channel of IC693ALG223 can be configured to receive 0-20 mA, 4-20 mA, and 4-20 mA enhanced signals. Some devices that can provide these signals are transmitters, variable frequency drives (VFDs) speed feedback, data recorders, panel instruments, and other devices.
IC693ALG223 is a single slot module that can be installed in any slot of the 90-30 series 5-slot or 10 slot backplane. The number of instances allowed by IC693ALG223 may vary depending on the installed controller. For 311, 313, and 323 systems, up to four (4) module instances can be compatible. For the 331 system, there are eight (8) modules, 12 for the 340 and 341 systems, and 51 for the 351 and 352 systems.
IC693ALG223 has a 12 bit resolution, an update rate of 13 msec for all 16 channels, and an absolute accuracy of 0.25% of full scale at 25 °. Celsius (77 degrees Fahrenheit): Within the specified operating temperature range, ± 0.5% of full scale, linearity is% 3C ± 1 LSB for the range of 4 to 20 mA, and% 3C ± 1 LSB for the range of 0 to 20 mA and the range of 4 to 20 mA enhancement, from 100 A to 20 mA. This module is designed with a 1500 volt isolation capability between the field side and the logic side.
The IC693ALG223 16 channel analog input module has an input filter response of 200 Hz and an input impedance of 250 ohms. For CPUs 311, 313, and 323, the maximum number of analog current input modules that can be installed in the system is 4; For CPU 331, it is 8; For CPUs 340 and 341, there are 12. It has a high level of resolution and accuracy, and can handle very sensitive analog signals. It can receive analog inputs from various sensors such as liquid level sensors, flow sensors, and temperature sensors. Each channel has an accuracy of 4 microamperes in the current range of 4 to 20 milliamperes, 5 microamperes in the current range of 0 to 20 milliamperes, and 5 microamperes in the enhanced current range of 4 to 20 milliamperes. It uses an external power supply with a voltage range of 20 to 30 volts DC and a power supply voltage ripple of 10%. This module aims to support a wide range of industrial signals
