Features of AH500 Series CPU module:
1. High efficiency

AH500 basic series CPU module: A 32-bit high-speed processor is used. The instructions are
executed at a speed of 3K steps/ms. (Fifty percent of the instructions are basic instructions, and fifty
percent of the instructions are applied instructions.)

AH500 advanced series CPU module: A 32-bit high-speed processor is used. The instructions are
executed at a speed of 12K steps/ms. (Fifty percent of the instructions are basic instructions, and fifty
percent of the instructions are applied instructions.)

AH500 redundant series CPU module: A 32-bit high-speed processor is used. The instructions are
executed at a speed of 12K steps/ms. (Fifty percent of the instructions are basic instructions, and fifty
percent of the instructions are applied instructions.)
2. Supporting more inputs and outputs

The AH500 series CPU module supports up to 4,352 local digital I/O or 544 analog I/O.

A complete AH500 system consists of eight backplanes at most, including a main backplane. Twelve
I/O modules at most can be installed on a main backplane, and eight I/O modules at most can be
installed on an extension backplane. Therefore, for the AH500 series CPU, sixty-eight digital
input/output modules at most or sixty-eight analog input/output modules at most can be installed.

Eight RTU modules at most can be installed on the main backplane.

I/O backplanes employ Ethernet communication protocol. Communication distance between
backplanes can be as far as 100 meters. If using fiber cables with fiber optics modules
AHAADP01/02EF-5A for extension backplanes, the communication distance can reach as far as 2
kilometers.
3. Multiple I/O modules

The I/O modules supported by the AH500 series CPU module are digital input/output modules, analog
input/output modules, temperature measurement modules, network modules, motion control modules,
and RTU modules. Refer to section 1.1.2 for more details.
