BMXDRA1605 Schneider Modicon X80 Relay Output Module

Schneider Electric BMXDRA1605 Modicon X80 Discrete Relay Output Module

The Schneider Electric BMXDRA1605 is a 16-channel discrete relay output module engineered for the Modicon X80 PLC automation platform. It serves as an interface between the controller and field devices, providing reliable electromechanical relay switching for actuators, contactors, solenoid valves, and indicator lamps in industrial automation applications.

Output Capacity and Voltage Ranges

The module features 16 non-isolated normally open (NO) relay output channels capable of handling both AC and DC loads. It supports operating voltages of 24 to 240 V AC and 24 to 48 V DC, with maximum switching limits of 264 V AC and 125 V DC. Each channel supports a maximum switching current of 2 A, with a conventional free air thermal current (Ith) of 2 A and a minimum switching load of 5 V DC at 1 mA.

Mechanical Performance and Electrical Isolation

Designed for high-frequency control, the relays deliver a mechanical service life of at least 20 million operations and support up to 3,600 cycles per hour. Output response times are rated at less than 8 ms for turn-on and less than 10 ms for turn-off. The module maintains a dielectric strength of 2,000 V AC (50/60 Hz for 1 minute) and an insulation resistance exceeding 10 MOhm at 500 V DC.

Field Wiring, Protection, and Diagnostics

Field connections are established via a 20-pin removable terminal block from the BMXFTB series. The module requires external fast-blow fuse protection per channel for short-circuit and overload safeguard. System status LEDs (RUN, ERR, I/O) and individual channel LEDs provide local diagnostic feedback. The unit supports hot-swapping under powered PLC rack conditions subject to system setup guidelines.

Frequently Asked Questions

Q: Does the BMXDRA1605 include internal fuse protection for the relay output channels? A: No, the module requires external fast-blow fuses on the output channels to protect the electromechanical relay contacts against short circuits and overloads.

Q: Can the BMXDRA1605 be replaced without turning off power to the Modicon X80 rack? A: Yes, the module supports hot-swapping, allowing field replacement while the backplane remains powered, provided system installation safety rules are observed.
