　　The IC697ALG320 is an advanced analog output module for the 90-70 series programmable logic controllers (PLCS), previously manufactured by GE Fanuc, not Emerson Automation. The module is designed to occupy A single slot on a 5-slot or 10-slot baseboard and draws a maximum current of 1.66A (8.3 Watts) (5VDC) from the backplane and 150 mA from the user's power supply to enable current output. The IC697ALG320 is equipped with four (4) individually configured output channels specifically designed to generate voltage and current outputs, 0-20 mA / 4-20 mA current output signals, and -10VDC / + 10VDC voltage output signals. It has a built-in digital-to-analog converter (DAC) circuit with a 16-bit resolution and monotonia, with voltages of 312.5 microvolts per LSB step and 0.5 microamps per LSB step from 4 to 20 mA. It has a maximum conversion rate of 2.0 ms for all analog output channels. The module is calibrated at the factory using calibration data stored in the module's EEPROM. It also has a continuous short-circuit function that does not cause any damage, and once the fault is resolved, the output will automatically return to the normal state. Analog output load specifications include a minimum of 2000 ms for resistive loads and a maximum of 1000 picometres for capacitive loads (configured for voltage operation). For current operation, resistive loads have output load specifications up to 700 ohms; The maximum capacitive load is 1.0 microfarad and the maximum inductive load is 250 millihenri. The accuracy of the module is affected by a specific temperature coefficient, the voltage is 25 PPM per degree Celsius, and the current operation is 50 ppm per degree Celsius.

　　The IC697ALG320 analog output module is a 4-channel analog output module manufactured by GE Fanuc. The module's four outputs can be individually configured for voltage or current operation. It provides bipolar or unipolar outputs with 16-bit resolution and 14-bit monotonicity. The update rate of the output is 2 milliseconds. It consumes a maximum power of 1.66 amps (8.3 Watts) at +5 volts, and the recommended operating voltage for this output module is 24 volts DC. Some of the module's features include fast update rates, individually configurable output channels for individual user scaling, factory calibration, and isolated output circuits. The IC697ALG320 analog output module also provides diagnostic functions such as out-of-range and off-range detection, open circuit detection, configuration error detection, and module health detection.

　　The GE IC697ALG320 analog output module is designed for the GE 90-70 series programmable logic controllers. The basic function of the module is to receive digital data from the control processing unit and perform digital-to-analog conversion to output analog signals. It ensures that the output is protected from overvoltage and transient conditions. It stores calibration data in its non-volatile EEPROM. Users can connect multiple IC697ALG320 output modules to archive up to 252 output channels. You are advised to connect a CPU rack to a maximum of seven modules and an extension rack to a maximum of eight modules. Configuration software can be installed on a PC to perform output range selection, user scaling, and fault reporting. User scaling provides the ability to easily convert output data into different units depending on the needs of a particular controller and application.
