Why the BMXART0814 Belongs on Your Upgrade Shortlist
Temperature measurement is one of the most common sources of hidden inefficiency in process plants. When an input module drifts, ages, or lacks isolation, you pay for it in scrap, rework, and unplanned downtime. The Schneider Electric BMXART0814 is an 8-channel temperature input module from the Modicon X80 series, and it is built to remove that risk from your control architecture.
This is a replacement and upgrade guide. If you run a Modicon M340 or M580 platform, the BMXART0814 gives you a direct, low-friction path to modernize temperature acquisition without rebuilding your I/O layout.
What You Get With This Module
The BMXART0814 accepts both RTD and thermocouple signals. RTD support covers PT100 and PT1000, while thermocouple support covers J, K, T, E, R, S, B, and N types. You configure the range per channel, so a single module can serve a mixed sensor population instead of forcing you to stock multiple part numbers.
Resolution is 16-bit. Accuracy is <= 0.1 C for RTD inputs and <= 1% for thermocouple inputs. Channel-to-channel isolation protects each measurement loop from electrical interference generated by neighboring channels. That isolation is a practical advantage in plants where motors, drives, and heaters share the same cabinet.
Diagnostics include a module status LED and per-channel status indication. Connection is made through a 28-pin terminal block.

Upgrade Fit for M340 and M580 Platforms
The BMXART0814 shares the Modicon X80 I/O platform used by both M340 and M580 controllers. That shared platform matters for buyers managing mixed installed bases. You can standardize on one temperature module across both controller families, which simplifies spare parts planning and reduces the number of line items your maintenance team must track.
The module draws 24 V DC via the backplane and consumes 3.6 W. Bus current is 150 mA at 24 V DC. Because power comes from the rack, you do not need a separate field supply for the module itself.
Where This Module Earns Its Place
Process temperature monitoring. In chemical or food processing lines, RTD inputs at <= 0.1 C accuracy support tight batch control. Channel-to-channel isolation keeps readings stable when adjacent loops switch heavy loads.
Furnace and kiln profiling. Thermocouple types J, K, T, E, R, S, B, and N cover a wide temperature spectrum. A single BMXART0814 can monitor multiple zones of a furnace, giving operators a complete thermal picture from one rack slot.
Retrofit projects. When an older temperature card fails, replacing it with a shared-platform X80 module reduces future obsolescence exposure. The 8-channel density also frees rack space compared with lower-density alternatives.
Installation and Setup Notes
Mount the module in a Modicon X80 rack and connect field wiring to the 28-pin terminal block. Confirm that the rack supplies 24 V DC on the backplane. Configure each channel for the correct sensor type and range before commissioning.
Respect the operating temperature range of 0°C to +60°C. Keep the cabinet within 5% to 95% relative humidity, non-condensing. The IP20 rating means the module requires a protected enclosure; it is not suitable for washdown or exposed field mounting.
Maintenance and Long-Term Reliability
Inspect terminal block connections periodically for looseness or corrosion. Verify per-channel status LEDs during routine rounds; a channel that drops out repeatedly may indicate a sensor or wiring fault rather than a module fault. Store spare units between -25°C and +70°C.
Because the platform is shared across M340 and M580, keeping one spare BMXART0814 on the shelf protects multiple controller families. That single spare strategy lowers inventory cost and shortens mean time to repair.
Buyer Checklist Before You Order
Confirm your controller platform supports Modicon X80 I/O. Verify your sensor types fall within the RTD and thermocouple list above. Check that your rack can supply 24 V DC and accommodate the module’s 100 × 28 × 93 mm footprint and 0.17 kg weight.
