Model: AC900F PM904F
AC 900F Controller
With the new award-winning AC 900F controller, Freelance DCS delivers more power, speed and functionality than ever before.
With years of experience in automation and control products, this newly released controller truly expands the Freelance Distributed Control System (DCS) hardware portfolio.

AC 900F The PM904F controller consists of a CPU module, which is the main component. Depending on the application and requirements, fieldbus modules and I/O modules can be added to the controller. Alternatively, the AC 900F supports redundancy.

The AC 900F includes:

The Plus CPU module PM 904F extends the functionality of the standard PM 902F to support up to four PROFIBUS or CAN communication interfaces and more application memory.
Standard CPU module PM 902F with 4 Ethernet interfaces, 1 diagnostic interface, 2 serial interfaces and display unit (optional). It supports up to two communication interfaces.
Lite CPU module PM 901F, with three Ethernet ports, one diagnostic port, two serial ports, and display unit (optional). It supports up to two communication interfaces.
Up to 10 S700 I/O modules are directly connected to the terminal device
The controller supports remote I/O, transmitters, actuators, drivers, and other devices, for example via PROFIBUS and other fieldbus protocols.
