SC1M5-8S5 supports conversion one master station RS485 and 8 slave stations RS485
The SC1M5-8S5 is an industrial-grade, isolated 8-port RS485 hub that expands a single RS485 master port into eight RS485 slave ports. It effectively facilitates the relaying, expansion, and isolation of RS485 networks.
The SC1M5-8S5 features an isolated RS485 master port and provides eight isolated RS485 slave ports.
Designed specifically for the harsh environments of industrial sites, the SC1M5-8S5 active isolated RS485 hub is ideal for applications requiring high reliability and safety. Its optoelectronic isolation capability effectively decouples the RS485 master and slave devices, protecting them from damage caused by ground potential differences, static electricity, lightning strikes, or surges. Furthermore, it prevents ground loops—which can arise from ground potential differences between devices—from damaging the RS485 equipment.
Key Applications:
1.Isolation: Effectively isolates the master and slave sides of an RS485 network, while also providing isolation between the eight slave ports.
2.Relaying: Extends the communication distance of an RS485 network.
3.Expansion: Expands one RS485 channel into eight, significantly increasing the number of RS485 devices that can be connected to the network.
Technical Features:
1.RS485 master and slave ports are equipped with optocoupler isolation protection.
2.Supports high baud rates of up to 460,800 bps.
3.Provides 2500V isolation for the master RS485 port, and 2500V isolation between the slave RS485 ports and the device's internal circuitry.
4.Features a built-in DIN-rail mounting slot on the rear for easy installation.
5.Supports a wide input voltage range of 9–24V.
