Specification
Brand : Yctze
BulletPoint1 : Robust Industrial Design: This 4-channel RS485 repeater features an industrial-grade design with complete photoelectric isolation, ensuring Durability-Optimized in various environments. With a communication rate of up to 115.2Kbps, it is ideal for demanding industrial applications that require reliable data transfer without interference.
BulletPoint2 : Comprehensive Electrical Isolation: The built-in DC/DC isolated power supply module provides an essential layer of protection by achieving electrical isolation between ports. This isolation minimizes the of equipment damage from electrical surges, making it a safe choice for critical installations where multiple devices are interconnected.
BulletPoint3 : Extended Communication Range and Capacity: Capable of supporting up to 128 nodes per interface, this RS485 hub can effectively manage complex networks. Its amazing communication distance of up to 2500 meters (using shielded twisted pair) ensures that signals remain intact over long distances, allowing for flexible installations in larger environments.
BulletPoint4 : Efficient Data Management: Featuring automatic control technology, this repeater intelligently distinguishes and manages data transmission directions without hindering performance. This streamlined functionality contributes to increased efficiency in multi-machine communication setups, reducing the chances of data loss or delays during transmission.
BulletPoint5 : Robust Protection Mechanisms: The repeater is designed with multiple layers of protection, including ±15KV ESD protection, 600W dual-channel TVS protection, and 2.5KV communication isolation. These features your devices against voltage spikes and electromagnetic interference, allowing for stable operation in high-demand situations.

Wiring Notes:
1. 485 communication line must use shielded twisted pair, preferably multiple strands for spare, the longest is not more than 2500 meters.
2. The wiring should be as far away as possible from high-voltage wires, not parallel to power lines, and not to be bundled together.
3. 485 bus must be a hand-in-hand bus structure, and resolutely eliminate star connection and bifurcation connection.
4. If there are more than 30 controllers or the cable length is greater than 500 meters, it is recommended to use a 485 repeater.
5. The AC-powered equipment and the chassis must be grounded and well grounded.
6. Connect the GND ground of all 485 devices with shielded wires.
Requirements For Wire Selection Using RS-485 Bus For Communication:
Use 2-core shielded twisted pair cable
Copper, wire diameter 0.5～0.75 square millimeter,
Impedance 38～88Ω/km,
Capacitive 30～50nF/km,
2-core shielded twisted-pair cable with a twisting distance of 20 mm (if the line distance is not more than 500 meters, the line standard can be appropriately reduced, but it must be a twisted pair)
Signal Common Ground:
1. All devices on the same network segment must have a unified signal ground to avoid common mode interference.
2. For centralized power supply, directly connect the DC negative poles of all power supplies on the same network segment (including the self-contained power supplies of communication equipment) to
