NW-BM85E485

The NW-BM85E485 from Schneider Electric is a dedicated Modicon communication Modbus accessory, enhancing connectivity within control systems. This device accepts an AC supply of either 115 or 230 VAC as well as a DC supply of 24 VDC. It incorporates a protection fuse rated at 1 A for DC applications. Power is conveniently connected via a rear-panel connector, enabling streamlined installation in various setups.

The operating temperature range of the NW-BM85E485 extends from 0 °C to 60°C, ensuring functionality across typical industrial environments. Additionally, the storage temperature can withstand extremes of -40 to 80 degrees Celsius. This unit is designed to function effectively in high humidity conditions, rated for a relative humidity level of 0 to 95% without condensation.

Climbing to a maximum altitude of 10,000 feet, this accessory is suited for diverse geographic installations. Communication is facilitated through four DB9S serial ports, allowing for direct connectivity to other Modbus devices. The baud rate is flexible, ranging from 50 to 19,200 baud to meet varying data transmission needs. Each connection can be finely tuned with link timeouts configurable between 100 milliseconds to 300 seconds, optimizing performance under specific operational conditions.

Data communication integrity is maintained with 8 data bits per transmission, and the device includes a routing table capable of handling 64 different Modbus Plus-to-serial connections. The unit's dimensions are 66 mm in height, 292 mm in width, and 211 mm in depth, making it compact enough to fit into standard control panel arrangements.
