Provides eight software-configured analog command channels.
Technical Summary
IC695ALG708-AB is the AB release of the PACSystems RX3i IC695ALG708 analog output module. Emerson identifies the family as an eight-channel current/voltage output module for rack-based RX3i I/O.
Channel behavior is controlled by the hardware configuration and the installed loop design. The AB suffix remains part of the spare identity even where family-level documentation uses IC695ALG708.
Replacement work should preserve range selection, scaling, terminal mapping, field power and receiving-device limits for every configured output.

Features
Supports current and voltage output applications within the approved module configuration.
Uses the RX3i rack and engineering environment for channel configuration and diagnostics.
Retains the AB release code for controlled spare selection.
Compatibility
- Confirm backplane slot, controller firmware and PAC Machine Edition support for the AB release.
- Match each configured signal range, scaling value and terminal assignment.
- Review field power, load limits, grounding, shielding and the receiving device input.
- Do not replace IC695ALG708-AB with IC695ALG728 or IC695ALG808 solely because each has eight outputs.
Replacement
- Capture the module label, hardware configuration and live channel record before shutdown.
- Move the controlled process to safe output states and isolate energy sources.
- Install the verified AB release and restore only the approved configuration.
- Test every used channel at representative values and prove the connected final element and permissive logic.
FAQ
Q01
How should the AB suffix be handled when ordering IC695ALG708-AB?
Keep the full suffix on the enquiry and provide the installed label and controller firmware so the proposed spare can be checked at release level.
Q02
Can IC695ALG728 be used for IC695ALG708-AB because both have eight channels?
Not without an engineering review. HART capability, firmware support and configuration behavior differ between module families.
Q03
What information prevents a current-versus-voltage mismatch on IC695ALG708-AB?
Provide the saved channel configuration, loop diagrams, terminal photographs, receiving-device input type and loop-load data.
Q04
How should process outputs be protected during IC695ALG708-AB exchange?
Use the approved shutdown or manual-control plan, document each safe state, isolate field circuits as required and control the return of automatic commands.
Q05
What commissioning record is appropriate for IC695ALG708-AB?
Record commanded and measured values for all configured outputs together with fault response, alarms, interlocks and receiving-device movement.
