Schneider Electric Modicon 340 BMXPRA0100
The Schneider Electric Modicon M340 BMXPRA0100 is a peripheral remote I/O adaptor module designed for the Modicon M340 Programmable Automation Controller (PAC) platform. The Modicon X80 range which is a common platform of modules for both Modicon M580 and M340 PACs.
Technical features and functions:
- The BMXPRA0100 allows a Modicon M340 CPU to communicate with and manage remote I/O racks over an Ethernet network using the EtherNet/IP protocol for device network. It enables the distribution of I/O points, reducing wiring costs and increasing system flexibility.
- It features one Ethernet port (RJ45 connector) for connecting to the remote I/O network. It supports Modbus TCP as well.
- It can configure and control a remote M340 I/O station with up to 4 remote racks.
- Memory Size is 48 kB of internal memory and 96 kB of removable memory.
- It is compatible with up to 1024 discrete I/O modules, up to 256 analog I/O modules, and up to 2 Ethernet modules in the remote configuration.
- It is designed for standard rack mounting within the Modicon M340 system.

Summery:
The BMXPRA0100 acts as a communication bridge, allowing your central Modicon M340 CPU to efficiently exchange data with I/O modules located in separate physical locations, connected via an Ethernet network. This is particularly useful for larger or distributed automation systems where centralized I/O wiring would be impractical or costly.
