In stock

Product Introduction:
The Triconex 9556-810F is a high-speed serial communication module for Triconex Safety Instrumented Systems. The “9556” identifies it as a multi-port serial communication module, “810” specifies 8 ports with 10 ports of additional capability (or 8 ports at high speed), and the “F” suffix indicates fiber optic connectivity. This board provides 8 independent RS-232/RS-485 serial ports, each capable of communicating with field devices, remote I/O racks, modems, GPS receivers, or other controllers at baud rates up to 115.2 kbps. The fiber optic “F” variant provides galvanic isolation and long-distance communication capability (up to 2 kilometers per fiber link). The TMR architecture ensures SIL 3 safety certification for all communication channels.

Functional Features:
Fiber Optic Isolation: Provides complete galvanic isolation between the Triconex backplane and field devices, eliminating ground loops and protecting against voltage transients.
8 Independent Ports: Each port operates independently, allowing simultaneous communication with 8 different devices or networks.
Long-Distance Communication: Fiber optic links extend communication range to 2 kilometers, far beyond the 15-meter limit of RS-232.
Protocol Flexibility: Each port can be configured for a different protocol, enabling integration with diverse field devices.
Per-Port Diagnostics: Monitors each port for errors, timeouts, and framing errors, reporting faults to the CPU.
Hot Swappable: Can be replaced while the system is running.
