ABB AC500 PLC - 1.2.1.1.1 Short Description; 1.2.1.1.2 Assortment

1.2.1.1.1 Short Description
The processor modules PM55x-xP and PM56x-xP are the central units of AC500-eCo. Their
main characteristics are:
● 128 kB (PM554-xP and PM564-xP types) program memory, 512 kB (PM556-xP and PM566-
xP types) program memory
● I/O bus (for expansion with max. 10 I/O devices)
● COM1 (serial RS-485 interface)
● 8 digital inputs (PM55x-xP), 6 digital inputs (PM56x-xP)
● 6 digital outputs
● 2 analog inputs (PM56x-xP only; the 2 analog inputs can be configured as digital inputs)
● 1 analog output (PM56x-xP only)
The various processor module variants differ in the following characteristics:
● Power supply (24 VDC or 100-240 VAC)
● Type of the digital outputs (transistor or relays)
● Ethernet interface (only models with suffix -ETH) - Analog inputs/outputs (only type PM56x-
xP)
All processor module variants can be expanded to include an memory card slot, a second serial
RS-485 interface (COM2) and an RTC (real time clock).
Details and technical data are provided in the technical data section.
