Product details

Overview

The 140CPU67261C is a Schneider Modicon Quantum Unity Hot Standby processor running at 266 MHz, built for redundant control over a single-mode fiber link up to 16 km between primary and secondary PLCs. It carries 11264 kB of internal RAM with 1536 kB reserved for data, supports 500 analog inputs/outputs and 31744 discrete I/O points, and is conformal coated with Humiseal 1A33.

For a panel originally specified around the 140CPU67861C, the 140CPU67261C shares the same form factor and backplane interface, but the 140CPU67861C carries 3072 kB of internal RAM versus 11264 kB on this unit, so a memory map review is needed before a direct swap.

The 140CPU67261C has 11264 kB internal RAM versus 3072 kB on the 140CPU67861C, and supports application-specific I/O for time stamping, counters, serial links, and high-speed interrupts.
