SKU: IoT-IC104
Price: 38.88 USD
Availability: InStock

Engineered to expand complex serial networks, this industrial isolated RS485 hub enables flexible star topologies by distributing signals from one master to four slave channels. It provides critical 2500V optical isolation and signal repeating to prevent ground loops and safeguard field devices across industrial data acquisition systems

Part No. 4CH-HUB-RS485

sku : IoT-IC104

INSTANT QUOTE

Primary function

Supports RS485 network relay, extension and isolation functions

Connection diagram

The isolated RS485 master port can be connected to the RS485 host device,

and the extended 4-ch isolated RS485 port can be connected to various RS485 slave devices,

such as RS485 sensors, etc.

Industrial isolation protection

The built-in photoelectric isolation protection circuit can effectively isolate RS485 master and slave devices to avoid the damage of ground potential difference between devices, anti-electrostatic, lightning-proof & anti-surge, which is suitable for the industrial environment with high reliability and safety requirements.

Wide baud rate range

Supports 300～460800 bps wide baud rate communication range (self-adaptive)

Rail-Mount Support

Supports 35mm standard guide rail with rail-mount buckle, easy to install.
