Product details

Overview

The 140CPU67261: It supports up to 31 remote I/O stations over S908 or Ethernet Quantum remote I/O, and integrates an Ethernet router with single-mode fiber optic interconnection for primary-secondary PLC links up to 16 km.

Schneider discontinued the 140CPU67261 on 2018-07-09.

Compared to the 140CPU67861, the 140CPU67261 has 3072 kB internal RAM versus 11264 kB, and expandable program memory of 7168 kB versus 8 MB file storage. Both support hot standby and process control, but the 140CPU67861 provides more headroom for larger programs and data logging. The 140CPU67261 is the right choice when the BOM matches the lower memory budget and the panel is already wired for the Quantum backplane.
