Technical specification parameters of FDC280 RH101FQ:
Processor and Memory: It uses a dual-core ARM® System-on-Chip (SOC), which has high-speed communication capabilities and ECC error detection functions. It can support up to 256 field devices, 8000 I/O points, and a total of 8252 blocks. The memory is 22MB, and the maximum block execution speed is 16,000 blocks per second.
Communication Capability: The Ethernet interface supports speeds of 10/100Mbps or 1Gbps and can be connected via copper cables or optical fibers. There are 4 serial interfaces, each of which can be configured as RS-232, RS-422, or RS-485, and it can support up to 128 RS-485 field devices.
Electrical Characteristics: The input voltage is 24V dc (redundant), and the maximum power consumption of a single module is 8.5W.
Environmental Adaptability: The operating temperature ranges from-20°C to 60°C, the relative humidity is 5% -95% (non-condensing), and it can operate at an altitude of up to 3000m. It can run in a Class G3 harsh environment and is protected by conformal coating.
Physical SpecificationsThe height of a single module is 105mm (116mm including mounting ears), the width is 51.8mm, and the depth is 147mm. The weight is 0.8kg. The fault - tolerant version consists of two processor modules.
In terms of network configuration, the FDC280 supports multiple configuration methods for Ethernet networks. In simplex mode, the non - fault - tolerant FDC280 can be directly connected to Ethernet field devices, which saves wiring. The fault - tolerant FDC280 can connect to Ethernet field devices through a separate network or a common network and supports different IP address settings.
Regarding serial network configuration, the simplex FDC280 is used to connect single - port serial field devices, while the fault - tolerant FDC280 can connect to both dual - port and single - port serial field devices, and can achieve RS - 232 connection through a Y - cable.
It has an excellent reliability design and supports multiple fault - tolerance mechanisms. At the control network level, two FDC280 modules installed on the same baseplate can achieve fault - tolerant communication through the "marriage" operation. The Core 1 CPU has fault - tolerance functionality, and the Core 2 CPU has redundancy functionality. The I/O - side redundancy ensures that on - site I/O signals are not affected during module replacement, effectively improving system availability.
In terms of control and diagnostic functions, the FDC280 is equipped with a variety of control algorithms, which can implement control strategies ranging from simple to complex. It also supports the self - hosting mode and can operate when the host workstation is offline. Meanwhile, it supports using diagnostic drivers to diagnose communication problems without affecting the device interface.
In terms of related accessories and installation, the FDC280 needs to be installed on a specific two - position DIN rail baseplate, which provides a variety of connection interfaces. There are two types of network adapters: fiber optic (RH924WA) and copper cable (RH924UQ), which are respectively connected to the Ethernet switch through specific cables. Serial communication requires the use of specific terminal components and cables.
