PLC Analog Output Signal Characteristics
The IC697ALG320 converts PLC output data into analog voltage or current signals. Its voltage range extends from -10 VDC to +10 VDC, while its current output supports 0-20 mA and 4-20 mA configurations. In addition, the module provides 16-bit output resolution with 14-bit monotonicity.
The supplied specifications state a 312.5 microvolt LSB step for voltage output. Furthermore, the module uses a 2.0 ms conversion rate. The external supply accepts 10 to 30 VDC, with 24 VDC identified as the typical value.
The module supports up to seven IC697ALG320 modules in one rack. Therefore, the stated maximum system capacity reaches 252 output channels when the applicable rack configuration uses seven four-channel modules.
Frequently Asked Questions

Field Installation Guidelines
Install the IC697ALG320 in the designated Series 90-70 rack slot and secure the module according to the rack hardware arrangement. Before wiring, verify the selected output type and the electrical requirements of the connected field device.
Route analog signal wiring separately from high-current power conductors and switching circuits where practical. Use appropriate shielded cable for low-level analog signals when the installation requires additional noise control. Terminate shields according to the site’s established grounding scheme.
Verify the external 10 to 30 VDC supply before energizing the module. For current outputs, also provide the specified user-supplied DC power. Finally, check terminal polarity, signal range, and load wiring before placing the output channel into service.
