CANopen CO401-MEM2

frenzel + berg CO401-Mem2 CANopen bus memory module with EEPROM

CO401Mem2 is a memory module with CANopen bus interface. This allows saving parameters or data in a non-volatile memory within CANopen bus applications.
The CO40Mem2 provides  4kByte of EEPROM memory. The memory is organized in two parallel memory banks to guarantee very high redundancy. The memory is represented by multiple objects within the CANopen object dictionary.

The CO401Mem2 integrates the CANopen draft standard DS401 (simple I/O device). The module already has the CAN transceiver (82C251) on board, so only few external components are required.
