Intended PurposeΒΆ

The CPUs PM554 and PM564 are the central units of the control system Advant Controller 500 (AC500). The main characteristics are:

  • 128 kB program memory
  • I/O-Bus (for expansion with max. 10 I/O devices since firmware V2.0.6, max. 7 I/O devices before firmware V2.0.6)
  • COM1 (serial RS-485 interface)
  • 8 digital inputs (PM554), 6 digital inputs (PM564)
  • 6 digital outputs - 2 analog inputs (PM564 only; the 2 analog inputs can be configured as digital inputs)
  • 1 analog output (PM564 only)

The various CPU variants differ in the following characteristics:

  • Power supply (24 V DC or 100-240 V AC)
  • Type of the digital outputs (transistor or relays)
  • Ethernet interface (only models with suffix -ETH)
  • Analog inputs/outputs (only type PM564)

All CPU variants can be expanded by a SD Memory Card slot, a second serial RS-485 interface (COM2) and a RTC (real time clock).
