HIMA F8650X Central Module
As the basic model in the same series as the F8651X, the HIMA F8650X also complies with the IEC 61508 SIL 3 safety standard and is compatible with PES H51q-MS, -HS, and -HRS systems. Equipped with dual INTEL 386EX 32-bit microprocessors operating at a 25 MHz clock frequency, it features 1 MB Flash-EPROM for the operating system, 1 MB Flash-EPROM for user programs, and 1 MB SRAM for data storage. The module supports two electrically isolated RS 485 interfaces, along with a 4-digit matrix diagnostic display and a safety-related watchdog function (24 V output, 500 mA load capacity, and short-circuit protection). With a physical specification requiring 8 SU of installation space and a power supply of 5 V/2 A, it can form a redundant configuration with the F8651X to enhance the overall fault tolerance of the system. This makes it ideal for small and medium-sized industrial control scenarios that are cost-sensitive while maintaining strict safety level requirements.
HIMA F8651E Central Module
The HIMA F8651E is a central module in the HIMAX series focusing on "compact design and low power consumption," also meeting the IEC 61508 SIL 3 standard. It is specifically designed for safety control systems with limited space, such as small chemical plants and nuclear power auxiliary equipment. Adopting a dual-core architecture to improve processing capability and fault tolerance, it is equipped with advanced diagnostic functions (continuous self-monitoring and external fault detection) that enable rapid problem localization and early warning. With a power consumption of ≤5 W, an operating temperature range of -20°C to +60°C, and dimensions of only 100mm×100mm×30mm, it can work in conjunction with the F8651X. In large-scale systems, it is responsible for safety logic control in local areas, reducing the load on the main module while maintaining consistent system safety levels.
HIMA F8627X Communication Module
The HIMA F8627X is a core communication expansion module for the F8651X, specifically designed for Ethernet network integration. Supporting SafeEthernet and Modbus TCP protocols, it enables the F8651X to connect with PADT (ELOP II TCP) and other Ethernet communication partners. Communicating with the F8651X central module via the backplane bus, it converts safety control signals into Ethernet-compatible formats, expanding the system's remote monitoring and data exchange capabilities. Starting from operating system version BS41q/51q V7.0-8, it can work with the F8651X to set bus station numbers in the range of 1-99, meeting the networking needs of multi-area equipment in large factories. It is commonly used in scenarios requiring long-distance safety control, such as oil refining and long-distance pipelines.
HIMA Safety Input/Output (I/O) Modules
The safety I/O modules compatible with the F8651X (e.g., the HIMA F869x series) offer a variety of input channels (for monitoring safety parameters such as temperature, pressure, and flow) and output channels (digital I/O, analog I/O). Equipped with electrical isolation and fault diagnosis functions, they can be directly integrated into the control logic of the F8651X. For example, the F8692X digital input module supports 16 safety input channels, and the F8694X analog output module supports 4 channels of 4-20 mA output, both complying with the SIL 3 standard. These modules can form a "central control + distributed I/O" architecture with the F8651X, adapting to the safety control needs of multi-parameter monitoring and multi-equipment linkage in the chemical and power industries.
