Schneider BMXDRA0805 Discrete Output Module

The Schneider BMXDRA0805 is an 8-channel discrete relay output module designed for use with Modicon M340 programmable logic controllers (PLC). This module allows the control of AC or DC loads by providing relay outputs, which are ideal for switching applications that require galvanic isolation and higher load capacity than transistor outputs can offer.

With robust relay contacts, the BMXDRA0805 module is suitable for switching inductive loads such as solenoids, contactors, and motors. The relay outputs provide electrical isolation between the logic system and the field devices, protecting sensitive control electronics. This makes the BMXDRA0805 an excellent choice for applications requiring safe switching of higher voltage and current loads in industrial automation.
