Schneider Electric BMXDRA0815 Modicon X80 Relay Discrete Output Module
The Schneider Electric BMXDRA0815 is an 8-channel relay discrete output module engineered for the Modicon X80 I/O platform. It provides eight individually isolated normally open (NO) relay contact outputs to drive AC and DC industrial loads. Compatible with both Modicon M340 and Modicon M580 programmable automation controllers, this module connects field devices using a removable 20-way terminal block and operates across a broad voltage range.

Relay Output Characteristics and Protection Requirements
The eight output channels operate as dry-contact normally open relays designed for isolated switching of control circuits, solenoid valves, and motor starters. Response times stay within 10 ms for activation and 13 ms for contact deactivation.
Verification: Confirm that individual channel load demands do not exceed the 3 A conventional thermal current rating over the operational voltage envelope.
The module does not include internal electronic fusing. External protection components—such as fast-acting line fuses for overcurrent protection alongside RC snubbers (for AC) or flywheel diodes (for DC) to clamp inductive kickback—must be installed in series with field wiring connections.
System Integration and Rack Installation
The module slots directly into standard Modicon X80 backplanes and interfaces with Modicon M340 or M580 CPUs. Operational power is drawn from the backplane bus, consuming 40 mA at 3.3 V DC and 101 mA at 24 V DC with a total module dissipation of 3.6 W.
Verification: Ensure a compatible 20-way removable terminal block (screw or spring clamp) is selected to match cabinet wiring requirements.
Field wiring terminates at a removable 20-way terminal block. Isolation between outputs and the internal backplane logic passes insulation testing exceeding 10 MOhm at 500 V DC inside IP20 control enclosures operating from 0 to +60 deg C.
Frequently Asked Questions
Q: Does the BMXDRA0815 module feature onboard short-circuit protection for its relay channels? A: No, it requires external fast-acting fuses and suppression components to protect the relay contacts against short-circuits, overloads, and inductive voltage spikes.
Q: What is the minimum signal load required for reliable relay contact operation? A: The minimum switching capability is rated at 5 V DC at 1 mA.
Q: Which controller series support the BMXDRA0815 output module? A: It is compatible with all Modicon M340 and Modicon M580 automation platforms utilizing the Modicon X80 I/O carrier architecture.
