The GE Fanuc IC693ALG221 is a robust Analog Current Input Module designed for use with the Series 90-30 Programmable Logic Controller. Featuring four input channels, this module excels at converting analog input signals into digital formats tailored for various applications. It offers two selectable input ranges: a default setting of 4 to 20 mA, where 4 mA corresponds to a count of zero and 20 mA scales to 32,000; and an adjustable range of 0 to 20 mA when configured with jumpers, allowing a full-scale output count of 32,000. Each input range provides a resolution of 12 bits, with a conversion speed of 0.5 milliseconds per channel and an update rate of 2 milliseconds across all channels. The module includes two range jumpers for flexibility in configuring channels 1-2 and 3-4. Input protection is designed to safeguard operations against common mode voltages up to 200 V, ensuring reliable performance even in electrically noisy environments. The IC693ALG221 requires twisted, shielded instrumentation cables for field connections and incorporates an LED indicator for power supply monitoring. Power consumption is rated at 25 mA from the +5V bus and 100 mA from the +24V bus, with the primary power source being +24 VDC. Factory calibration ensures precision with an accuracy rating of 0.1% at full scale.
