Schneider Electric BMXAMI0810H Modicon X80 Analog Input Module

Configured for high-speed analog signal acquisition in the Modicon X80 platform, the Schneider Electric BMXAMI0810H (BMXAMI0810H analog input module) provides eight isolated current or voltage inputs with 15 bits plus sign resolution, configurable digital filtering, and a fast read cycle for Modicon M580 and M340 PAC systems.

Hardware Specifications

Channel Isolation and Analog Signal Processing

The BMXAMI0810H provides eight isolated analog channels for current and voltage measurement. Supported current ranges include +/- 20 mA, 0-20 mA, and 4-20 mA. Voltage ranges include +/- 10 V, +/- 5 V, 0-10 V, 0-5 V, and 1-5 V.

Channel isolation is specified at 300 V DC between channels and 1400 V DC between channels and both ground and the bus. The module provides a minimum 80 dB crosstalk attenuation and 80 dB common mode rejection. These characteristics define the electrical separation and signal rejection available between independently wired analog channels.

The module uses first-order digital filtering. The fast read cycle is 1 ms plus 1 ms for each channel used, while the nominal read cycle is 9 ms with all eight channels active.

Frequently Asked Questions

Q: What analog signal ranges can the BMXAMI0810H accept?
A: The module accepts +/- 20 mA, 0-20 mA, 4-20 mA, +/- 10 V, +/- 5 V, 0-10 V, 0-5 V, and 1-5 V input ranges.

Q: What isolation levels are specified for the analog channels?
A: The specification states 300 V DC isolation between channels and 1400 V DC isolation between channels and ground and between channels and the bus.

Q: What is the power consumption of the module?
A: At 24 V DC, power consumption is 1.06 W typical and 1.50 W maximum. Current consumption is 54 mA at 24 V DC.

Field Installation Guidelines

Install the BMXAMI0810H on the applicable Modicon X80 rack and connect the 28-way field connector according to the module wiring documentation.

Route analog signal wiring separately from high-voltage power conductors, motor cables, and high-current switching circuits where practical. Maintain the specified channel isolation when connecting signals from electrically independent field devices.

Use shielded instrumentation cable where required by the installation environment. Terminate cable shields according to the control cabinet grounding scheme and avoid creating unintended ground loops.

Verify the selected input range against the actual field transmitter or voltage source before commissioning. For 4-20 mA circuits, confirm loop polarity and current range configuration. For voltage inputs, verify signal reference and common wiring before energizing the channel.

The BMXAMI0810H has conformal coating and an operating range of -25 to 70 deg C. Installation should nevertheless maintain the environmental conditions specified for the complete Modicon X80 assembly.
