Emerson IC695ALG626 PACSystems RX3i HART Analog Input Module
A 16-channel single-ended or 8-channel differential analog input module with HART communication.
Product Overview
Emerson IC695ALG626 is a PACSystems RX3i HART Analog Input Module identified by the complete submitted catalog string. The suffix and revision characters remain part of the supply identity.
Selection of IC695ALG626 should follow the installed label, rack or controller record, field wiring and the verified technical details below; a neighboring family number is not treated as interchangeable.
Technical Register
Operating Features
The module acquires up to sixteen single-ended or eight differential analog input channels.
HART communication supports compatible smart field instruments through the approved control architecture.
The channel count and wiring mode are configuration alternatives, not values that can be mixed without engineering review.
The exact IC695ALG626 identity distinguishes it from non-HART ALG616 and lower-channel ALG628 variants.
Applications
- RX3i process measurement systems using compatible HART transmitters.
- Analog retrofit projects that preserve single-ended or differential channel wiring.
- Maintenance where device variables, channel scaling and diagnostic handling are documented.
Service Control
- Export the PAC Machine Edition hardware configuration, channel scaling and HART device records.
- Photograph the terminal assembly and identify field-powered versus loop-powered circuits.
- Confirm the selected single-ended or differential mode before moving any conductor.
- After installation, validate raw values, engineering units, loop response, HART access and alarm behavior channel by channel.
FAQ
Why must IC695ALG626 channel mode be documented before replacement?
Its published capacity is sixteen single-ended or eight differential channels, so the physical wiring and project configuration must agree.
Can IC695ALG626 be replaced with the non-HART IC695ALG616?
Do not assume equivalence. IC695ALG626 adds HART communication, which may be required for device access, diagnostics or asset records.
What HART evidence is useful with an IC695ALG626 enquiry?
Provide the configured channel map, device tags, field-power arrangement, terminal photographs and the host project revision.
How should an IC695ALG626 loop be checked after exchange?
Verify zero and span, engineering-unit scaling, live current response, HART communication and the configured fault/alarm action.
What prevents IC695ALG626 from being confused with IC695ALG628?
Use the complete label and channel requirement: IC695ALG626 is the 16 single-ended/8 differential HART input module.
