Frequently asked questions

Q : Does the ME203/CN require an external power supply module for its backplane?

No, it features an integrated 17W power supply unit that powers itself and adjacent connected I/O modules directly via the backplane.

Q : How much non-volatile data can I retain during a power outage?

The module contains 512 kB of battery-backed SRAM dedicated to retaining persistent variables and retain-tags.

Q : What is the maximum data rate supported by the integrated CAN interface?

The onboard CAN/CANopen interface supports standard industrial transmission speeds up to 1 Mbit/s.

Q : What is the input voltage requirement for the module?

The module requires a stable nominal input of 24 VDC (-20% / +25% tolerance).

Product Applications

Wind Power: This is Bachmann's core application area. The ME203 is frequently used as the controller for the main control system, pitch system, or yaw system of wind turbines, capable of stable operation in the harsh, high-vibration, and large-temperature-difference environments of medium to large-scale wind farms.

Marine & Rail: Used in train control systems and ship power control and engine room management systems, meeting multiple international maritime and rail safety certifications. Renewable Energy: Applied to grid-connected control systems for large-scale photovoltaic power plants, energy storage system management, and real-time data acquisition and monitoring on the grid side.

Heavy Industrial Manufacturing and Intelligent Equipment: Used for automated production line control in paper mills, steel mills, and large material handling equipment.
