Emerson IC695ALG708 RX3i Analog Output Module
An eight-channel PACSystems RX3i analog output module for configured current and voltage control signals.
Product Overview
IC695ALG708 is a PACSystems RX3i analog output module with eight configurable current/voltage output channels. It belongs to the rack-based RX3i I/O family used in mission-critical discrete and process applications.
A replacement must preserve each channel range, scaling, fallback behavior, terminal wiring and controller reference. The module should be commissioned as part of the complete output loop rather than judged from an unloaded value alone.
Performance
- Provides eight analog output channels in one RX3i rack position.
- Supports configured current and voltage output applications.
- Integrates with RX3i controller diagnostics and project-based channel configuration.
- Offers the standard RX3i rack-based mechanical and backplane interface.
- Supports process actuators and analog setpoint paths within the approved module limits.

FAQ
What information is required for an IC695ALG708 quotation?
Provide the full label, rack and slot, controller and firmware, PAC Machine Edition release, terminal assembly and a channel list with current/voltage range, load and fallback state.
Can IC695ALG708 be replaced while actuators remain in automatic control?
Use the site-approved maintenance strategy. Outputs must be placed in a controlled safe or manual state, with fallback and process risk addressed before wiring is disturbed.
Why should an IC695ALG708 output be tested under load?
An unloaded reading does not prove loop power, field wiring, burden, polarity, actuator response or controller scaling; the complete channel needs a controlled functional test.
What should be checked if an IC695ALG708 channel reaches the wrong endpoint?
Review configured range and scaling, project reference, terminal wiring, loop power, field load, fallback configuration and actuator calibration.
Can another RX3i analog output module replace IC695ALG708 directly?
Only after channel count, signal ranges, isolation, terminal hardware, diagnostics, firmware support and the application project have been compared.
