Fanuc Corporation GE Fanuc | ANALOG INPUT MODULE - IC693ALG220
The IC693ALG220 is a Channel Analog Voltage Input module designed for the Series 90-30 Programmable Logic Controller. It provides four input channels, each capable of converting an analog input signal to a digital signal. The module supports input voltages ranging from -10 to +10 volts and offers a conversion speed of 1 ms per channel, resulting in an overall update rate of 4 ms.
Signal resolution is 12 bits binary, and user data in the %AI registers is in 16-bit 2’s complement format. The module features a limited current input mode with a jumper on the user terminal connector for each channel. The jumper can connect the internal 250 ohm shunt resistor to the circuit, enabling a -40 to +40 mA current input range. Users should monitor input current to prevent self-heating of the input resistor, which could affect current accuracy.

The IC693ALG220 is a 4-channel Analog Voltage Input module designed for the Series 90-30 Programmable Logic Controller by GE FANUC. It converts analog input signals to digital signals with a resolution of 12 bits binary. Each channel can handle input voltages ranging from -10 to +10 volts and operates at a conversion speed of 1 ms per channel, resulting in an update rate of 4 ms per channel.
Equipped with a limited current input mode, the module features a jumper on the user terminal connector for each channel. This jumper can connect the internal 250 ohm shunt resistor to the circuit, allowing for a current input range of -40 to +40 mA. Users must monitor input current to prevent self-heating of the input resistor, which could affect current accuracy.
The primary power source for the IC693ALG220 is isolated +24 VDC supplied via the PLC power supply. Voltage undergoes regulation via an inverter/regulator to yield operating voltages for the module. The module draws 27 mA from the +5 VDC output of the PLC power supply.
For user convenience, the module features an LED indicator located near the top of the faceplate. During normal operation, the LED emits an ON status, alerting the user to operational status. The module employs optical isolation to create electrical isolation between field wiring and the backplane, effectively isolating external noise.
