NW-RR85-001 Schneider Electric Bridge Communication Module IP20 -25 ° C To+70 ° C

NW-RR85-001 Schneider Electric Bridge Communication Module IP20 -25 ° C To+70 ° C

1. Product Overview
The NW-RR85-001 is a DIN rail-mounted serial-to-fieldbus converter from Schneider Electric, designed specifically for Modicon, TeSys, and other Schneider Electric systems. It converts RS-485 Modbus RTU signals into reliable, isolated industrial signals, enabling easy integration into PLC, SCADA, and DCS networks. With an operating temperature range of -25°C to +70°C and an IP20 protection rating, this module is designed for continuous 24/7 operation in harsh environments such as factories, power plants, and infrastructure facilities.

2. Key Features and Advantages
- Multi-protocol support: Supports Modbus RTU master/slave mode, ASCII mode, and transparent mode; automatically detects baud rates from 9600 to 115200 bps
- Isolated RS-485 port: 2-wire + shielded cable; connects up to 32 nodes without a repeater; maximum cable length of 1200 meters at 19200 bps
- Plug-and-play diagnostics: Three-color LED indicator shows transmit/receive, collision, and error status; Schneider Electric "Data Suite" configuration wizard simplifies commissioning
- Wide power supply range: 20.4-28.8 V DC (rated 24 V), power consumption < 2 W, reverse polarity protection
- Hot-swappable: Can be replaced without disconnecting power when used with Schneider Electric STB or M340 frames
- Reliability certifications: CE, UL 508, CSA, C-Tick, RoHS; Vibration resistance 2g, Shock resistance 15g; MTBF ≥ 300,000 hours
