B+B SmartWorx RS-232 Isolated Repeater, DIN Rail

Meet the 232OPDR, a rugged DIN Rail mountable RS-232 optical isolator and repeater designed for harsh industrial environments. This compact device delivers robust galvanic isolation and reliable signal regeneration, ensuring your RS-232 networks stay safe from ground loops, voltage transients, and electrical noise. Ideal for factories, process automation, and control cabinets, the 232OPDR protects both equipment and operators while preserving the integrity of data transmissions over longer distances.

• High-voltage protection for sensitive gear: Provides up to 2000 V isolation for four RS-232 signal lines, safeguarding connected devices from damaging voltage spikes and ground potential differences. Each line remains electrically isolated, helping to prevent costly equipment damage.
• Duplex, four-line isolation: Two RS-232 signal lines in each direction are isolated, enabling true bidirectional communication with multiple devices without compromising line integrity or introducing ground loops.
• DIN Rail mounting for industrial setups: Designed for quick, secure installation inside control panels and cabinets. Its compact form factor fits neatly on standard DIN rails, simplifying deployment and future maintenance.
• Clear status indicators: Four LED indicators show data flow on each isolated line, while a dedicated power LED confirms the unit is powered and operational, making diagnostics fast and straightforward.
• Easy wiring with terminal block connections: All connections are made to a straightforward terminal block, providing reliable, tool-friendly wiring for rugged industrial environments and minimizing connection looseness over time.
