IC695ALG608 is a PACSystems RX3i analog input module for voltage and current measurements. The documented channel architecture supports eight non-isolated single-ended inputs or four differential inputs.

The module belongs to the RX3i rack-based I/O family designed for process and discrete applications with configurable I/O and diagnostics. Range selection, wiring mode and scaling must be preserved channel by channel when the module is replaced.

• Supports eight single-ended input channels when the application uses the common-reference arrangement.
• Supports four differential channels when the engineered signal path requires differential measurement.
• Accepts voltage and current input configurations within the approved RX3i module setup.
• Provides RX3i module diagnostics for commissioning and maintenance workflows.
• Uses the rack-based RX3i mechanical and backplane architecture.

• Export every channel mode, range, scaling, filter and diagnostic setting from the approved project.
• Record terminal positions, commons, shields, loop supplies and whether each signal is single-ended or differential.
• Verify rack power and controller/module firmware compatibility before inserting IC695ALG608.
• Restore wiring by checked loop schedule and keep voltage and current circuits separated from unsupported configurations.
• Inject known signals in each configured mode and verify raw data, engineering units, alarms and controller logic.

• Voltage and current acquisition in PACSystems RX3i process-control racks.
• Eight-channel single-ended installations where the documented common-reference arrangement is appropriate.
• Four-channel differential measurement applications requiring the approved wiring mode.
• Revision-controlled replacement of an installed RX3i analog input module.
