Quantum Analog Interface
The 140CFK00400 is a CableFast terminal block for the Modicon Quantum I/O platform, now obsolete. It provides four connection point sets for analog input modules, each point allocated six terminals — covering plus, minus, shield, and both field and loop power configurations. The SUB-D 50 female connector mates directly to the I/O module, and the block mounts on standard DIN rail.
Sourcing Reality
Schneider has discontinued the 140CFK00400. No direct successor is listed, so any replacement would require migrating away from the Quantum platform. For existing installations, sourcing runs through surplus or broker channels.
