I-7520U4-G RS-232 to 4-ch RS-485 Active Star Wiring Hub, Isolated
Isolated RS-232 to four-channel RS-485 active star wiring hub with independent drivers, selectable baud rate modes and 3000 VDC intra-module isolation.
- One RS-232 master input forwarded simultaneously to four independent RS-485 outputs in a star topology
- Independent RS-485 driver on each channel with automatic direction control
- Self-Tuner baud rate mode (300 ~ 115200 bps) or fixed baud rate mode (1200 ~ 115200 bps) selected with a rotary switch
- Short-circuit protection automatically isolates a breakdown RS-485 channel
- Jumper-selectable 120Ω termination resistor per channel, disabled by default
- Power and data flow LED indicators for troubleshooting

Produktinformasjon "I-7520U4-G RS-232 to 4-ch RS-485 Active Star Wiring Hub, Isolated"
The I-7520U4-G CR takes one RS-232 master input and forwards its data simultaneously to four independent RS-485 outputs, allowing a single serial master to reach several RS-485 devices in a star topology. Each output channel has its own driver, and the hub switches direction automatically.
Baud rate is set by the rotary switch, with a choice between Self-Tuner mode, which supports multiple baud rates and data formats, and a fixed baud rate mode, which is better suited to long or lossy lines and electrically noisy surroundings. A short-circuit protection feature switches off a faulty RS-485 channel so that the remaining devices keep communicating.
Each channel includes a 120Ω termination resistor that is jumper selectable and disabled by default, useful where signal reflections must be controlled. Power and communication LEDs assist with troubleshooting, and the plastic DIN-rail unit runs from +10 VDC to +30 VDC over an operating range of -25 ~ +75 °C.
Applications
- Distributing serial data from one RS-232 master to several RS-485 slave devices
- RS-485 networks running over long lines or in electrically noisy environments
- Industrial serial communication cabinets with DIN-rail installation
