GE Fanuc IC693ALG220

The IC693ALG220 is a Channel Analog Voltage Input module designed for use with the GE Fanuc Series 90-30 Programmable Logic Controller (PLC). This module features four input channels, each capable of converting an analog voltage input in the range of -10 to +10 volts into a digital signal tailored to user specifications. Each channel offers a conversion speed of 1 millisecond, resulting in a comprehensive update rate of 4 milliseconds per channel. The output signal is presented in a 12-bit binary format, while user data is stored in 16-bit 2’s complement format within the %AI registers. The module includes a limited current input mode and a jumper on each channel's user terminal connector, facilitating connections to a built-in 250-ohm shunt resistor for current inputs from -40 to +40 mA. Careful monitoring of input current is essential to prevent self-heating of the input resistor, which may compromise current accuracy. The primary power for the IC693ALG220 is sourced from the PLC's isolated +24 VDC power supply, which is processed through an inverter/regulator to supply necessary operating voltages. The module draws 27 mA from the +5 VDC output of the PLC. An operational LED indicator, located on the front face of the module, provides visual status feedback, illuminating during normal operations. The design incorporates optical isolation to safeguard against external electrical noise between field wiring and the backplane, and it is recommended that field connections utilize twisted/shielded instrumentation cable to minimize capacitive loading and interference. The IC693ALG220 is an essential component for integrated automation solutions, characterized by its robustness and precision in analog signal management.
