Following years of experience in automation and control products, this newly released controller truly extends the hardware portfolio of the Freelance distributed control system (DCS).
The AC 900F controller consists of a CPU module, which is the main component. According to the application and requirements, fieldbus modules and I/O modules can be added to the controller. Optionally, AC 900F supports redundancy.
The AC 900F consists of:
- Plus CPU module PM 904F who expands the capability of the Standard version PM 902F and supports up to four communication interfaces for PROFIBUS or CAN as well as more application memory.
- Standard CPU module PM 902F with four Ethernet interfaces, one diagnostic interface, two serial interfaces and display unit (optional). It supports up tp two communication interfaces.
- Lite CPU module PM 901F with three Ethernet interfaces, one diagnostic interface, two serial interfaces and display unit (optional). It supports up to two communication interfaces.
- Up to ten S700 I/O modules directly attached on terminal units
The controller supports remote I/Os, transmitters, actuators, drives and other devices, for example through PROFIBUS and other fieldbus protocols.
