FREQUENTLY ASKED QUESTIONS

Technical Specifications:

Q: What are the primary analog signal ranges supported by the module inputs and outputs?

A: The module supports 0 to 10 V, -10 to 10 V, 0 to 20 mA, and 4 to 20 mA signal ranges.

Wiring & Installation:

Q: What is the required external power supply voltage range for the module to function?

A: The external power supply must be rated from 20 VDC to 30 VDC, typically 24 VDC.

Troubleshooting & Compatibility:

Q: What action can the analog output channels be configured to take during a power interruption?

A: Outputs can be configured to Hold Last State or revert to the low end of the current power range.

Replacement & Upgrades:

Q: Is there a path to upgrade from older GE Fanuc Series 90-30 systems to the RX3i platform?

A: The RX3i system is designed to allow a migration path, supporting the reuse of certain Series 90-30 modules on RX3i backplanes.
