Schneider Electric BMXAMM0600 Modicon X80 Mixed Analog I/O Module

The Schneider Electric BMXAMM0600, also cataloged as the BMXAMM0600 Mixed Analog I/O Module, provides four non-isolated analog inputs and two non-isolated analog outputs for voltage and current signal acquisition and generation within the Modicon X80 platform. It occupies one rack slot and uses a 20-way connector.

Hardware Specifications

Analog Signal Integrity and I/O Conversion

The BMXAMM0600 uses separate configurable voltage and current ranges for its four analog inputs and two analog outputs. Input conversion supports 0-20 mA, 4-20 mA, 0-5 V, 1-5 V, 0-10 V, and +/-10 V. Output conversion supports 0-20 mA, 4-20 mA, and +/-10 V.

The input channels use firmware-based first-order digital filtering. The specified minimum crosstalk attenuation is 70 dB, with 80 dB common mode rejection. Input measurement error varies with signal range and temperature, with supplied specifications ranging from 0.25% to 0.5% of full scale for current inputs and up to 0.35% of full scale for voltage inputs under the stated conditions.

The module provides fallback operation through predefined or configurable behavior. Status indication includes RUN, channel diagnostic, ERR, and I/O LEDs.

Frequently Asked Questions

Q: Are the four analog input channels galvanically isolated from each other?
A: No. The analog inputs are specified as non-isolated between channels. The module nevertheless specifies 1400 V DC isolation between channels and ground and between channels and the bus, plus 750 V DC between groups of I/O channels.

Q: What signal ranges can the analog inputs accept?
A: Each input can be configured for 0-20 mA, 4-20 mA, 0-5 V, 1-5 V, 0-10 V, or +/-10 V operation.

Q: What is the specified power consumption?
A: Consumption is 2.6 W typical and 3.2 W maximum at 24 V DC, with an additional 0.35 W typical and 0.48 W maximum at 3.3 V DC.

Field Installation Guidelines

• Install the module in a compatible Modicon X80 rack and secure the module according to the rack installation procedure.
• Use the specified 20-way connector and verify terminal assignments before applying field signals.
• Keep analog signal wiring separated from high-current switching, motor, and power wiring where practical.
• Connect cable shields according to the plant grounding scheme and the applicable Modicon X80 installation requirements.
• Verify the configured input or output range against the connected field instrument before energizing the channel.
• Do not exceed the specified input overload limits or output maximum conversion values.
• Check RUN, ERR, I/O, and channel diagnostic LEDs after startup.
• Maintain the specified 0 to 60 deg C operating environment and IP20 enclosure conditions.
• Verify signal polarity and current-loop wiring before commissioning voltage or current channels.
