GE IC693ALG391F Analog Output Module

FAQ

Q1: What is the GE Fanuc IC693ALG391F used for?
The IC693ALG391F is a 2-channel analog output module for the Series 90-30 PLC. It converts digital values from the PLC CPU into analog current or voltage signals used for controlling industrial devices such as control valves, drives, and actuators.

Q2: How many analog output channels does the IC693ALG391F provide?
The module provides two independent analog output channels, allowing two field devices to receive separate control signals from the PLC.

Q3: What output signals are supported by the IC693ALG391F?
The module supports 0–20 mA, 4–20 mA current outputs, and 0–5 VDC or 1–5 VDC voltage outputs. Output ranges can be selected according to application requirements.

Q4: What is the resolution of the IC693ALG391F?
The module provides 12-bit digital-to-analog conversion. The resolution is approximately 4 μA per count for 4–20 mA output and 5 μA per count for 0–20 mA output.

Q5: Does the IC693ALG391F require an external power supply?
Yes. The module requires a 20–30 VDC external supply in addition to the Series 90-30 backplane power. It uses +5 VDC from the backplane and isolated +24 VDC for output operation.

Q6: What type of loads can be connected to the IC693ALG391F?
The module can drive analog devices such as proportional valves, variable speed drives, process controllers, and other equipment requiring standard industrial current or voltage control signals.

Q7: What does the “F” revision indicate?
The “F” suffix identifies the hardware revision of the IC693ALG391 analog output module. Revision letters represent production and lifecycle updates while maintaining compatibility with Series 90-30 PLC systems.

Q8: What should be checked before replacing an IC693ALG391F module?
Before replacement, verify the Series 90-30 baseplate compatibility, output range settings, external 24 VDC supply, field wiring, load requirements, PLC configuration, and analog scaling parameters to ensure correct operation after installation.
