Installation Guidelines
- Ensure the PLC rack power is disconnected before installing or removing the module.
- Verify that the module is fully seated in the backplane slot and secured with the provided mounting screws.
- Use shielded twisted-pair cabling for analog signals to minimize electromagnetic interference (EMI).
- Ensure the external 24 VDC power supply is properly grounded and within the specified 20-30 VDC range.
- Maintain adequate clearance around the module to allow for proper heat dissipation and airflow within the enclosure.
- Avoid routing analog signal cables alongside high-voltage AC power lines.
FAQ
What is the primary function of the IC693ALG391F module?
This module serves as an analog output interface for the GE Series 90-30 PLC, converting digital data from the controller into analog current signals to drive external process equipment.
Can this module be powered by the backplane?
The module requires both +5 VDC from the backplane and an external +24 VDC supply. The 24 VDC can be sourced from the backplane (if supported by the power supply) or provided by an external user-supplied source.
What is the resolution of the output signals?
The module features a 12-bit digital resolution, providing 4 microamps resolution for the 4-20 mA range and 5 microamps for the 0-20 mA range.
