Overview
The 140NOA62200 is a Modicon Quantum Interbus master module, generation 4, in standard format with CE marking. It acts as the Interbus master on the Quantum backplane, handling the bus scan and data exchange for up to 256 kB of memory. Communication runs over an isolated RS485 link at 500 kbit/s per DIN 66020, using two SUB-D 9 connectors for the Interbus ring. The module draws 4.0 W from the backplane and is compatible with Quantum CPUs including 140CPU11303, 140CPU43412A, and 140CPU53414B.
Integration
Mounts in a local Quantum rack; the Interbus link uses twisted-pair cable with a maximum device-to-device distance of 20 m. The module is addressed as a master node and requires Concept or ProWORX 32 software (V 2.5 SR2) for configuration. Front-panel LEDs give direct status: green for CPU active, module run, and Interbus data; red for module fault, initialization fault, master not operational, Interbus fault, memory fault, peripheral bus fault, processor fault, and remote bus fault; yellow for bus segments shut down.
Schneider lists the 140NOA62200 as discontinued. No official successor is named in the available records; sourcing now runs through surplus and broker channels. Send an RFQ to confirm available quantity and lead time for line-down or last-time-buy needs.
