Features & benefits

• Eight configurable isolated channels allow mixed current/voltage inputs per channel for maximum installation flexibility.
• Genuine channel isolation (300 V) and high isolation to ground/bus (1400 V) reduce ground‑loop errors and increase measurement safety.
• High resolution and low drift deliver accurate process values for control loops and monitoring.
• Per‑channel diagnostics and status LEDs simplify commissioning and fault finding.
• Compact Modicon X80 form factor and removable 28‑way terminal block speed wiring and maintenance.

Applications

• Process industries, water/wastewater, chemical plants, utilities, manufacturing and other applications requiring multi‑channel isolated analog acquisition for closed‑loop control and monitoring.

Installation and service notes

• Wire sensors/transmitters to the 28‑way removable terminal block following Schneider Electric wiring diagrams. Verify per‑channel range selection prior to commissioning.
• Respect isolation ratings when planning grounding and bus wiring. Install in IP20‑rated cabinets and follow ambient/humidity limits.
• Consult datasheet for wiring details, range configuration, filtering, shielding and firmware compatibility (SV01.80). Internal recalibration removes need for external recalibration procedures.
