Schneider Electric BMXART0414 Modicon X80 Analog Isolated Low Level Input Module

Configured for isolated low-level analog signal acquisition in the Modicon X80 platform, the Schneider Electric BMXART0414 (BMXART0414 Analog Input Module) provides four isolated input channels with configurable voltage, resistance, temperature probe, and thermocouple measurement functions. The module uses a 40-way connector and occupies one rack slot.

Hardware Specifications

Industrial Control and I/O Characteristics

The BMXART0414 provides four independently isolated analog acquisition channels within one Modicon X80 rack slot. Its low-level ranges extend from +/- 40 mV to +/- 1.28 V, while resistance and temperature configurations support multiple 2-wire, 3-wire, and 4-wire sensor arrangements. The module performs 16-bit sigma-delta conversion with a stated analog resolution of 15 bits plus sign.

Channel and bus isolation are specified at 1400 V DC, while channel-to-channel and channel-to-ground isolation are specified at 750 V DC. Common-mode rejection is 120 dB at 50/60 Hz and differential-mode rejection is 60 dB at 50/60 Hz.

The module supports internal recalibration and first-order digital filtering. Temperature and thermocouple configurations use external Pt100-based cold junction compensation where specified. The source lists SV2.3 as the latest firmware version for the product.

Frequently Asked Questions

Q: How many analog channels does the BMXART0414 provide?

A: The module provides four isolated low-level analog input channels.

Q: What signal types can be connected to the BMXART0414?

A: Depending on configuration, the inputs support low-level voltage, 400 Ohm and 4000 Ohm resistance, temperature probes, and thermocouples.

Q: What is the specified module power consumption?

A: The source specifies 150 mA at 3.3 VDC and 40 mA at 24 VDC.

Field Installation Guidelines

Install the BMXART0414 in its designated Modicon X80 rack slot and connect the field wiring through the specified 40-way connector. Confirm the configured input type before wiring each channel because voltage, resistance, temperature probe, and thermocouple configurations use different electrical measurement arrangements.

For low-level analog signals, route sensor wiring separately from high-current power conductors and switching circuits. Maintain appropriate shielding and grounding practices for the installation environment. Use the specified wiring configuration for 2-wire, 3-wire, or 4-wire resistance and temperature sensors.

Verify the selected input range against the connected sensor before commissioning. For thermocouple and temperature measurements, confirm the external Pt100 cold junction compensation arrangement where applicable. Check RUN, channel diagnostic, ERR, and I/O status indicators during startup. The module has IP20 protection and an operating temperature range of 0 to 60 deg C.
