Description
The Schneider BMXART0814 is an 8-channel analog input module (Low Level / High Resolution) for the Modicon M340 / M580 (Premium Eco — M340 only; M580 uses X80 analog — BMX = M340 family) PAC rack. It provides galvanic isolation per channel group (or overall — check manual: ART = isolated inputs, 8 single-ended inputs, 4 differential pairs — BMXART0814 has 8 inputs configurable as 8 single-ended or 4 differential, all with channel-to-bus isolation) and 16-bit resolution (plus sign where applicable) for precise measurement of voltage (±10V, ±5V, 0–10V) and current (0–20mA, 4–20mA) signals from transmitters, transducers, or low-level sensors.
Key differentiators vs standard BMXAMI0800:
- BMXART0814 = ART series — Higher Resolution (16-bit + sign), Isolated inputs (channel/bus isolation), Low-level capability (can measure smaller spans with better accuracy) — suited for weighing, temp (via transmitter), pressure with high precision.
- Standard AMI0800 = 12-bit resolution, non-isolated or group-isolated — lower cost, general purpose.
Module is configured in Unity Pro / Control Expert (formerly Unity Pro) — each channel independently assignable to voltage or current range via hardware configuration (drop-down per channel — no DIP switches).
Key Features
- Channels: 8 analog inputs — configurable per channel as Single-Ended (8 ch) or Differential (4 ch pairs)
- Resolution: 16 bits + sign (17-bit total word incl. sign — raw value -32768…+32767 or 0–65535 depending on range)
- Input Ranges (SW Selectable): ±10 V, ±5 V, ±2.5 V (some ART ver.), 0–10 V, 0–20 mA, 4–20 mA
- Isolation: Galvanic isolation between analog inputs (group) & backplane bus (≥ 500 V AC typical)
- Accuracy: ± 0.1% of Full Scale (typical — better than standard 12-bit AMI module)
- Conversion Time: ~ 5 ms per channel (fast scan) — all 8 ch scanned each cycle
- Country of Origin: France / Germany / China (Schneider Global)
Model & Capability Table (Modicon M340 Analog Input Modules)
Model | Channels | Resolution | Isolation | Best For |
|---|---|---|---|---|
BMXART0814 | 8 AI (SE or Diff.) | 16-bit + sign (17-bit word) | Yes (Ch-Bus isol.) | Precision process (weighing, temp via xmtr, press.) |
BMXAMI0800 | 8 AI (SE) | 12-bit + sign (13-bit word) | Group iso. (not ch-ch) | General purpose 4–20mA / 0–10V |
BMXAMI0410 | 4 AI (Diff./SE) | 16-bit + sign | Yes | Fewer ch but high-res — if only 4 ch needed |
⚠️ Important Fit Checks:
%IWwords — applySCALE_XorNORM_X * input range + offsetto convert raw -27648…+27648 (or -32768…+32767 for 16-bit) to engineering units. ART module raw range matches selected range (e.g., 4–20mA → 0–22000 or ±32768 depending on SW setting — newer Unity uses -32768…+32767 for bipolar 16-bit).

Warranty & After-Sales
- Factory new units: 12 months warranty
- Refurbished units: 3-6 months warranty (analog loopback — inject 4–20mA/0–10V → read %IW in Unity test)
- Technical support for:
- M340 rack compatibility confirmation (BMX = M340 only — NOT M580 X80!)
- Unity Pro / Control Expert HW config (range per channel, SE vs Diff wiring impact)
- Wiring diagram (shielded twisted pair, COM terminal tie, separation from digital I/O cables)
- 20-pin terminal block identification (spare BMXXTB0080) & pinout
- Scaling (NORM_X + MUL — raw -32768…+32767 or 0–65535 → eng. units like bar/°C/ton)

- Spare terminal blocks (BMXXTB0080) & prefabricated cables (BMXXCAUSB018 — for connecting to field terminal if remote TB used? Actually BMX modules HAVE the removable TB on-board — BMXXCAUSB are extension cables with TB at far end for remote termination — optional)
