140NOA62200

Operating effectively as an Interbus master module, the Schneider Electric part number 140NOA62200 offers robust capabilities for industrial control systems. This module is designed to handle environmental conditions, tolerating relative humidity levels up to 95% without condensation. It functions efficiently within an operating temperature range of 0°C to 60°C and can be stored across a broad temperature spectrum from -40°C to 85°C.

This unit is equipped with two SUB-D 9 connectors, which facilitate reliable electrical connections for the Interbus link. For diagnostics, it features multiple LEDs, including green indicators for communication status, firmware operation, and Interbus data transmission. Red LEDs signal any faults related to initialization, memory, processor integrity, or remote bus issues, while a yellow LED indicates shutdowns in bus segments.

The module is engineered for local rack compatibility, dissipating 4 watts of power with a bus current requirement of 800 mA. Incorporating various memory types, it includes 128 kB and 256 kB firmware EPROM, 64 kB for Interbus command sequences, as well as combined 256 kB and 32 kB RAM for data handling, and 2 kB dual-port RAM for enhanced communication processes. The maximum cable length supported by this module is up to 20 meters, utilizing twisted pair cabling for effective signal transmission. Additionally, it employs the Interbus communication protocol at isolated RS485 with a transmission speed of 500 kbit/s, conforming to DIN 66020 standards.
