P0917YZ | Foxboro Field Control Processor 270 (FCP270)

The FOXBORO P0917YZ FCP270 Field Control Processor 270 is a distributed, optionally fault-tolerant, field-mounted controller that performs process control and alarming functions according to a user-defined control strategy.

Key Features and Functions:

• Performs regulatory, logic, timing, and sequential control together with connected Fieldbus Modules (FBMs).
• Performs data acquisition and alarm detection and notification.
• Supports up to 32 200 Series FBMs (Compact or standard).
• Supports up to 128 200 Series FBMs with a Fieldbus Expansion Module 100 (FEM100).
• Supports up to 64 of the 100 Series FBMs.
• No Fieldbus Communication Module is required.
• Connects to the MESH control network via standard fiber optic 100 Mbps Ethernet.
• Utilizes a rugged, die-cast aluminum housing for mounting in a non-vented field enclosure.
• Can operate in Class G3 harsh environments.
• Is CE certified for field mounting in enclosures.
• Supports both the 2 Mbps or 268 Kbps HDLC fieldbuses simultaneously, allowing connections to both 200 Series and 100 Series FBMs.
• Offers unique, patented, fault-tolerant operation using two control modules to improve reliability relative to other process controllers.
• Employs versatile control algorithms and a wide variety of FBMs for control capabilities across a broad range of process applications.
