Schneider BMXNOR0200H Coated RTU I/O Module

Schneider BMXNOR0200H Modicon X80 Remote I/O Serial Module

Product Introduction

The Schneider Electric BMXNOR0200H is part of the Modicon X80 series. This remote I/O serial module carries a conformal coating. That coating protects the internal circuitry from moisture, dust, and chemicals. Furthermore, the module provides one serial port. The port supports both RS232 and RS485 standards. It runs Modbus RTU protocol for distributed I/O. Therefore, it links remote field devices to a central controller. This unit shares the same I/O platform as the M340 and M580.

Technical Specifications

The BMXNOR0200H offers one application channel. Specifically, it includes one built-in serial port. That port handles RS232 or RS485 signals. The module operates with Modbus RTU protocol. In addition, it functions as a remote terminal unit for distributed I/O. The X-bus backplane carries both data and power. Meanwhile, the module occupies a single slot. This compact footprint saves rack space in dense cabinets.

Electrical Parameters

Supply voltage for the BMXNOR0200H is 24 V DC. The backplane delivers this power directly. Power consumption reaches 1.9 W. Besides, bus current draw is 80 mA at 24 V DC. These values help engineers plan power budgets. The low current demand suits dense rack configurations. Therefore, the module runs cool and efficient.

Mechanical and Environmental Data

The module measures 100 × 28 × 93 mm. It weighs only 0.15 kg. The housing carries an IP20 protection rating. Operating temperature ranges from 0°C to +60°C. Storage temperature spans -25°C to +70°C. Relative humidity stays between 5% and 95%. However, condensation must not occur. The conformal coating adds extra resilience. As a result, the BMXNOR0200H handles harsh industrial settings better than standard modules.

Installation Guide

First, verify the X-bus backplane has an open slot. Next, align the BMXNOR0200H with the slot guides. Then slide the module firmly into place. After that, tighten the retaining screw. The backplane supplies 24 V DC power automatically. No external wiring is needed for supply. For serial connections, use the front port. Specifically, choose RS232 or RS485 mode. Finally, configure Modbus RTU settings in your software. The module is now active as a remote terminal unit.

FAQ

Q1: What makes the BMXNOR0200H different from the BMXNOR0200?
A: The BMXNOR0200H carries a conformal coating. This coating protects against moisture, dust, and chemicals. The standard BMXNOR0200 lacks this protection layer.

Q2: Which serial standards does this module support?
A: The BMXNOR0200H supports both RS232 and RS485. You can select either mode through configuration. One port handles both standards.

Q3: How much power does the module consume?
A: Power consumption is 1.9 W. Bus current draw is 80 mA at 24 V DC. The backplane provides all needed power.

Q4: Can I use this module in harsh environments?
A: Yes, the conformal coating adds protection. The operating range is 0°C to +60°C. It carries an IP20 rating. Therefore, install it inside a control cabinet. Avoid condensing humidity above 95%.

Q5: What shipping options are available?
A: We ship via Fedex, UPS, and DHL. Each order includes the module, original box, and foam insert. Delivery times vary by destination.
