PLC Analog Output Signal Characteristics
The IC693ALG392 converts PLC output data into either analog current or voltage signals. The eight channels support independent output points within the specified current and voltage ranges. For voltage operation, the module provides 0.312 mV resolution for both 0-10 V and -10 to 10 V ranges.
For current operation, the resolution differs by range. The 4-20 mA range uses 0.5 microamps resolution, while the 0-20 mA range uses 0.625 microamps resolution. Therefore, the selected signal range directly determines the output resolution.
The module receives its internal supply from the 5 VDC PLC backplane and also requires an external 20 to 30 VDC supply. Consequently, installation must account for both the backplane load and the user-supplied 24 VDC circuit.
Frequently Asked Questions
Q: How many analog output channels does the IC693ALG392 provide?
A: The module provides 8 analog output channels.
Q: What analog signal ranges does the IC693ALG392 support?
A: It supports 4-20 mA and 0-20 mA current outputs, plus 0-10 V and -10 to 10 V voltage outputs.
Q: What power sources does the IC693ALG392 require?
A: The module uses 5 VDC from the PLC backplane and accepts an external supply from 20 to 30 VDC.
Field Installation Guidelines
Install the IC693ALG392 in the specified Series 90-30 PLC rack position and secure the module against connector misalignment. Before wiring, isolate the external 20 to 30 VDC supply and verify the field circuit requirements.
Route analog signal wiring separately from high-current switching conductors and other sources of electrical noise. Use appropriate shielded instrumentation cable where the installation requires noise control. Terminate cable shields according to the plant grounding scheme and avoid creating unintended ground loops.
Verify the selected current or voltage range before connecting each field circuit. Check polarity, common connections, and external supply wiring before energizing the module. Also confirm that the connected load matches the requirements of the selected output signal.
Because the IC693ALG392 has a discontinued/obsolete lifecycle status, verify the installed PLC configuration and replacement compatibility before modifying an existing rack.
