Overview
Essential details：IC697ALG320D GE Series 90-70 PLC analog output module
The IC697ALG320 is a high-level analog output module from the series 90-70 Programmable Logic Controller (PLC) that is formerly manufactured by GE Fanuc, not by Emerson Automation. This module is designed to occupy a single slot of a 5-slot or 10-slot baseplate and draws current from the backplane amounting to a maximum of 1.66A (8.3 Watts) at 5VDC and 150 mA from the user power supply to enable current output. The IC697ALG320 comes with Four (4) individually configured output channels that generated voltage and current outputs specifically, 0-20 mA / 4-20 mA current output signal and -10VDC / +10 VDC voltage output signals. It has built-in digital to analog converter (DAC) circuit with a resolution of 16-bits with monotonicity specifically, 312.5 microvolts per LSB step on voltage and 0.5 microamps per LSB step on 4 to 20 mA. It has a maximum sequential conversion rate of the conversion rate of 2.0 ms for all analog output channels. This module is factory calibrated with calibration data stored with the EEPROM of the module. It is also provided with a continuous short circuit without harm with the output automatically returning to normal state once the fault is addressed. Analog output loading specifications include a minimum of 2000 ms for resistive loads and a maximum of 1000 picofarads for capacitive load when configured for Voltage operation. For current operation, output loading specifications are up to 700 ohms for resistive loads; maximum of 1.0 microfarad for capacitive loads, and 250 miliHenry for inductive loads. The module’s accuracy is affected by a specific temperature coefficient with 25 PPM per Degree Celsius for Voltage and 50 ppm per degree Celsius for the current operation.

IC697ALG320D GE Series 90-70 PLC analog output module
The IC697ALG320 Analog Output Module is a 4-channel analog output module made by GE Fanuc. The 4 outputs of the module can be configured for voltage or current operation individually. It provides bipolar or unipolar outputs with 16 bits of resolution with 14 bits of monotonicity. The update rate of the outputs is 2 milliseconds. It consumes a maximum of 1.66 Amps (8.3 Watts) of power at +5 Volts and the recommended operating voltage of this output module is 24 Volts DC. Some of the features of this module include a fast update rate, individually configurable output channels with individual user scaling, factory calibration, and isolated output circuitry. The IC697ALG320 Analog Output Module also offers diagnostic facilities such over range and under range detection, open-wire detection, configuration error detection, and module health detection.
The GE IC697ALG320 Analog Output Module is designed for use with the GE Series 90-70 programmable logic controllers. The basic function of the module is to receive digital data from the control processing unit and perform a digital to analog conversion in order to output an analog signal. It ensures that the output is protected against overvoltage and transient conditions. It saves the calibration data in its non-volatile EEPROM. The users can connect multiple IC697ALG320 Output Modules to archive up to 252 output channels. It is recommended to connect a maximum of 7 modules in a CPU rack and a maximum of 8 modules in the expansion rack. The configuration software can be installed in a PC to perform output range selection, user scaling, and fault reporting. The user scaling provides the facilities to easily convert the output data into different units according to the needs of specific controllers and applications.
