ABB PM802F 3BDH000002R1 Control Module

Hardware Architecture: It adopts a high-performance superscalar RISC CPU with strong performance and a 16K internal CPU cache RAM for fast data processing.

Storage Capacity: The main memory is 4MB static RAM with a battery retention function, enabling quick startup after the recovery of the main power supply. It is also equipped with a 16K bit serial EEPROM for storing hardware configurations, diagnostic data, etc.

Communication Interfaces: There are 2 slots that use fast DMA technology for direct high-speed data communication with the CPU, and Ethernet modules can be inserted to transmit Ethernet information based on the standard TCP/IP protocol. In addition, there are 4 slots (F1…F4) that exchange data with the CPU and main memory through interrupts, and each module can generate interrupt sources. The data bus bandwidth of the CPU board is 100MB/s.

Power Parameters: It features dual power supply redundant input, with a voltage range of DC12-36V (typical value DC24V), power consumption less than 4W, reverse connection protection function, and uses industrial terminal interfaces.

Safety Features: The safety module can be freely configured, with 20 safety inputs and 4 safety outputs, 4 signals, 2 clocks, and 2 grounding switch outputs. Diagnostics can be performed through the bus gateway, meeting SIL 3, Cat. 4/PL e, and SIL 3 safety levels (EN 50156).

Other Features: It has functions for monitoring the internal temperature of the device and a watchdog function. It supports self-diagnosis of modules and networks, and modules can be hot-swapped and repaired online for easy maintenance. Real-time data is retained when power is off, with redundant verification and quick recovery to ensure the security of system information.
