Main Functions
- AX670 (3BSE000566R1) is mixed analog input‑output eurocard module for legacy ABB Advant 500 / MOD300 DCS system. It realizes both field analog signal acquisition and analog control output in one single board.
- 8‑channel analog input collects 4‑20 mA / 0‑10 V process signals from transmitters, sensors for pressure, flow, level and temperature measurement.
- 8‑channel analog output converts controller set‑point values into 4‑20 mA /0‑10 V analog signals to drive field control devices such as control valves and positioners.
- Group‑wise galvanic isolation separates field‑side signals from internal DCS bus circuits, suppressing industrial electromagnetic interference and surge damage.
- Module hardware self‑diagnosis monitors channel status, detects open‑loop, short‑circuit and module internal faults, and reports fault codes to Advant operator station for maintenance guidance.
- Typical field failure symptoms
- Partial or full channel signal loss for AI or AO channels
- Analog output drifting, valve cannot keep stable position
- Advant DCS reports AX670 module hardware fault alarm
- Intermittent signal abnormality triggered by cabinet vibration
Common root causes: ageing of analog conversion components, output driver circuit damage, gold‑plated edge‑connector contact oxidation, dust contamination.
- Pure maintenance‑oriented spare‑part component, only for repair and replacement of existing legacy Advant 500 / MOD300 DCS installations; not suitable for new‑project engineering deployment.
Typical Applications
- Spare‑part replacement for AX670 mixed analog I/O module inside ABB Advant500 / MOD300 DCS rack.
- On‑site troubleshooting scenarios: analog measuring channel failure, control valve output abnormality, AX670 module fault alarms.
- Preventive‑maintenance spare‑part inventory preparation for power plant, pulp‑paper, chemical legacy Advant DCS system.
- Hardware refurbishment for decommissioned Advant 500 controller assemblies.
