I-7514U-G Isolated 4-ch RS-485 Active Hub, Gray Cover
Isolated 4-channel RS-485 active star hub that repeats one master input to four independent outputs, with 2500 VDC intra-module isolation and DIN-rail mounting.
- One RS-485 input with four independent RS-485 outputs, each with its own driver
- Self-Tuner baud rate detection from 300 ~ 115200 bps, or fixed 1200 ~ 115200 bps via rotary switch
- Automatic shut-off of a faulted branch to protect the rest of the network
- Jumper-selectable 120 Ω termination resistor on each channel, disabled by default
- 2500 VDC intra-module isolation and ESD protection (IEC 61000-4-2)
- Hubs can be daisy-chained for up to 256 channels

Produktinformasjon "I-7514U-G Isolated 4-ch RS-485 Active Hub, Gray Cover"
I-7514U-G CR is an active RS-485 star wiring hub for extending or splitting a serial bus. One RS-485 input connects to the master, and each of the four outputs has its own driver, so data from the master is forwarded to all four slave branches at the same time.
Baud rate can be handled automatically or fixed. The Self-Tuner mode accepts 300 ~ 115200 bps, while the fixed mode, set by rotary switch, runs from 1200 ~ 115200 bps and suits long or lossy cable runs and electrically noisy sites. If a connected device fails, its short-circuit protection isolates that branch so the remaining outputs keep working. Each channel also has a jumper-selectable 120 Ω termination resistor, disabled by default.
The gray-cover variant is supplied with a plastic casing, 2500 VDC intra-module isolation and a +10 VDC ~ +30 VDC non-isolated power input. Hubs can be daisy-chained to reach 256 channels, and LEDs show power, transmit and receive activity.
Applications
- Star-wired RS-485 network distribution
- Extending serial bus reach on long or noisy lines
- Splitting one master RS-485 port across multiple slave devices
