IC693ALG221 GE Fanuc Analog Input, Current, 4 Channel

Product Description of IC693ALG221

IC693ALG221 is an Analog Current Input Module with four input channels for the Series 90-30 Programmable Logic Controller. This controller’s channels are each capable of converting an analog input signal into a digital signal as needed for the application. Two input ranges are available with a default of 4 to 20 mA with scaled user data so 4 mA corresponds to a count of zero and 20 mA to 32000. Each 1000 count represents 0.5 mA. If a jumper is added to the I/O terminal board, the input range is adjusted to 0 to 20 mA with scaled user data scale corresponding to a count of 32000 with each 800 count equal to 0.5 mA. This module is equipped with two range jumpers: one for channels 1-2 and one for channels 3-4.

The IC693ALG221 input module allows conversion speed of one half milliseconds for each of the channels with an update rate of two milliseconds for any of the provided channels. Resolution speed on a converted signal is 12 bits over either chosen range. Percent AI user data registers in 16 bit 2’s complement format. If the current source is reversed into the input, the module will output a data word that parallels to the low end of the range.

Input protection for the IC693ALG221 is sufficient to work with reduced performance with up to 200 V in common mode settings. This module also allows electrical isolation of external noise. All field connections require a good grade twisted, shielded instrumentation cable connected to the COM or GND. An LED indicator monitors power supply operation. The main power source specific to the IC693ALG221 is +24 VDC supplied PLC power routed through an inverter for the module. IC693ALG221 uses power from the +5 VDC output to drive isolation circuitry.

The IC693ALG221 is an analog input module that is part of the Series 90-30 Programmable Logic Control (PLC) system. This module is a component module that functions as an analog input module. This module features Four (4) input channels, receiving 0-20 mA and 4-20 mA input signals from field devices and instruments. This module is equipped with an internal Analog to Digital converter (ADC) which enable the PLC to process and further condition the signal for use in the user program.

The IC693ALG221 has input resolution of 12-bit with each input range having a resolution of 4 µA (1 LSB = 4 µA) for 4-20 mA input signal and 5 µA (1 LSB = 5 µA) for 0-20 mA input signal. It has an absolute accuracy of 0.1% full scale + 0.1% reading with common mode voltage of 200V. Additionally, this module has linearity of < 1 Least Significant Bit and input filter response of 325 Hz.
