Key Features&Specifications
Function:The F8621A primarily serves as a coprocessor module or CPU module for HIMA’s Programmable Electronic Safety Systems(PES),such as the H41q/H51q series.It provides additional processing power,memory,and communication interfaces to enhance the capabilities of these safety systems.
Microprocessor:It’s equipped with an HD 64180 microprocessor,operating at a clock speed of 10 MHz.
Memory:
384 KB static memory:This typically comprises a combination of CMOS-RAM and EPROM.
Dual Port RAM:For fast memory access,enabling efficient communication with other central modules in the system.
Battery Buffer:For the RAMs(often supported by a separate power supply monitoring module like the F 7131).
Communication Interfaces:
Two RS-485(half-duplex)interfaces:These interfaces are galvanically isolated to ensure robust and interference-free communication in industrial settings.
Configurable Baud Rates:Supports various transmission rates including 300,600,1200,2400,4800,9600,19200,38400,and 57600 bps.Baud rates can be set via software or DIP switches.
Data Format Selection:Allows selection of ASCII,binary,or mixed data formats.
CRC Error Checking:Includes Cyclic Redundancy Check for data integrity.
Modbus RTU Protocol Support:Often supports Modbus RTU for integration with other systems.
Safety Standards:While specific SIL(Safety Integrity Level)ratings for the F8621A itself are integrated into the overall system’s certification,HIMA systems are known for complying with high safety standards like IEC 61508 SIL3 and EN 954-1 Category 4,which the F8621A contributes to.
