Schneider BMXDRA0804T X80 Relay Output 8Ch

Schneider BMXDRA0804T Modicon X80 Relay Output Module

Product Introduction

The BMXDRA0804T is a relay output module from the Schneider Electric Modicon X80 series. This unit provides 8 relay output channels in an SPDT configuration. Specifically, it switches loads from 5-240 V AC or 5-30 V DC, which covers a wide range of field devices. Moreover, the module serves both M340 and M580 controllers because both platforms share the X80 I/O family.

Furthermore, channel-to-channel isolation protects each output from electrical interference. As a result, the BMXDRA0804T handles mixed AC and DC loads within one module. Additionally, per-channel diagnostic LEDs make troubleshooting fast and clear.

Technical Specifications

The module offers 8 relay output channels with SPDT contacts. The contact rating spans 5-240 V AC and 5-30 V DC. Because the signals are discrete, resolution and accuracy values do not apply.

Isolation uses a channel-to-channel design. This approach prevents fault propagation between outputs and improves noise immunity. Meanwhile, per-channel diagnostic LEDs report contact state and fault conditions.

Relay outputs suit applications that need dry contacts. For instance, they can drive solenoids, lamps, and small contactors directly. Furthermore, they isolate the control system from the load circuit.

Connection uses a 20-pin terminal block. This standard interface allows quick wiring and easy replacement. Furthermore, the terminal design reduces installation time on site.

Electrical Parameters

The BMXDRA0804T receives its load supply from the field, either AC or DC. Meanwhile, the internal bus draws power at 24 V DC with a current of 90 mA. Its power consumption is 2.2 W. These modest values help keep cabinet power budgets under control. Therefore, engineers can populate racks with multiple modules without oversized supplies.

Environmental and Mechanical Data

Operating temperature ranges from 0°C to +60°C. Storage temperature spans -25°C to +70°C. Relative humidity stays between 5% and 95% without condensation. The protection rating is IP20, so the module belongs inside a clean control cabinet.

Physically, the unit measures 100 × 28 × 93 mm (H×W×D) and weighs 0.18 kg. Its slim 28 mm width saves valuable DIN rail space. Besides, the compact housing matches all other Modicon X80 modules for a uniform panel look.

Installation Guide

First, mount the module onto a compatible X80 rack and tighten the retaining screws. Next, wire the 20-pin terminal block according to your field device scheme. Then, verify the load voltage stays within the relay contact rating before powering the rack.

After power-up, check each channel LED during output commands. A correct command should change the matching channel indicator. Finally, configure the module inside EcoStruxure Machine Expert or Unity Pro. Always follow Schneider's grounding rules to preserve isolation performance.

FAQ

1. Which controllers work with the BMXDRA0804T?
It works with Modicon M340 and M580 controllers. Both platforms share the Modicon X80 I/O family.

2. What load voltage does this relay module support?
The SPDT contacts handle 5-240 V AC or 5-30 V DC. This range covers many AC and DC field devices.

3. Why choose a relay output instead of a transistor output?
Relay outputs provide dry contacts and isolate the load circuit. Therefore, they suit mixed AC/DC loads and higher voltage switching.

4. What diagnostics does the BMXDRA0804T provide?
It offers per-channel diagnostic LEDs. These indicators help locate wiring faults and stuck contacts fast.
