Schneider Electric BMXAMI0800 Modicon X80 Analog Input Module — 8‑Channel High‑Level, 0–20mA / 4–20mA / ±10V, 15‑bit + sign, Non‑Isolated Channels, IP20

The Schneider Electric BMXAMI0800 is an 8‑channel high‑level analog input module in the Modicon X80 family, designed for medium to large process applications. It accepts mixed current and voltage inputs per channel and provides high resolution (15‑bit + sign) acquisition in a compact IP20 module that mounts on Modicon M340/M580 racks.

Features & benefits

• Eight mixed‑range channels allow per‑channel selection of current or voltage inputs for flexible field wiring.
• High resolution and low drift ensure accurate process measurement and stable control loops.
• Factory calibration and per‑channel diagnostic LEDs simplify commissioning and maintenance.
• Compact Modicon X80 form factor with 28‑way removable terminal block reduces installation time and rack space.

Applications

• Distributed I/O for process control, water/wastewater, manufacturing, utilities and applications requiring multi‑channel analog acquisition where channels are non‑isolated to one another but have high isolation to ground/bus.

Installation and service notes

• Connect sensors/transmitters to the 28‑way removable terminal block following Schneider Electric wiring diagrams.
• Verify channel configuration and input range before commissioning. Because channels are non‑isolated (50 V between channels), plan grounding and signal wiring to avoid ground loops and common‑mode errors.
• Operate within specified ambient and humidity ranges; install in IP20‑rated enclosures. Refer to the product datasheet for wiring diagrams, shielding, termination, and firmware compatibility (SV01.80).
