Product Overview
Downtime on an Interbus segment can stall an entire production line. The 140NOA62200C from Schneider Electric solves that problem as a Modicon Quantum Interbus master module built for severe environments. It manages Interbus generation 4 networks over isolated RS485 twisted pair cabling, giving you a practical, ready-to-ship spare for oil, gas, and industrial automation racks.
This module fits local Quantum racks and pairs with controllers such as the 140CPU53414B, 140CPU43412A, and 140CPU11303. Its 128 kB plus 256 kB firmware EPROM and 2 kB dual-port RAM keep command sequencing local, which reduces reliance on the host CPU and protects cycle time.

What These Specs Mean for Cost
The 4 W power dissipation and 800 mA bus current draw keep cabinet heat and power supply sizing predictable. The 20 m twisted pair limit supports compact cells without extra repeaters. The 0 to 60 °C operating range and 95 % non-condensing humidity tolerance reduce enclosure cooling costs in harsh plants.
Where It Fits
In oil and gas terminals, this module links remote I/O drops to a Quantum CPU across a skid or pump house. In automotive body shops, it coordinates Interbus generation 4 devices on a local rack. In water treatment, it keeps valve and sensor networks on a single twisted pair run, cutting cabling material and installation labor.
Installation and Setup
Mount the module in a local Quantum rack and connect the Interbus link through the SUB-D 9 connector. Keep cable runs within the 20 m limit and route twisted pair away from drives. The front LEDs show ACTIVE, RUN, IS-B RUN, and fault states, so technicians can confirm health at a glance. Software support includes Concept and ProWORX 32, version V 2.5 SR2.
Integration Note
Interbus RS485 networks may require an external gateway or connection module when bridging to other fieldbuses. Confirm cables and gateways with your supplier before commissioning.
Maintenance and Reliability
Check LED status during routine rounds and inspect connectors for corrosion in humid areas. The 4 kV contact and 8 kV air electrostatic discharge resistance, plus 10 V/m immunity from 80 to 1000 MHz, help the module survive electrical noise. That resilience lowers nuisance trips and protects your maintenance budget.
Selection Checklist
Before ordering, verify your CPU compatibility, rack type, and cable length. Confirm the Interbus generation matches your network. Oil AutoTech provides hands-on technical selection help and fast dispatch, worldwide.
