Technical Specifications

General Information

Core Functional Capabilities

Multi-Input Validation Logic
These modules implement advanced three-signal processing logic commonly used in safety-critical control loops:

• Three-input averaging for stable measurement output

• Median value selection under normal operating conditions

• Automatic reconfiguration to dual-input mode if one signal becomes invalid

• Continuous operation during maintenance or sensor failure

This logic improves measurement reliability and minimizes process disruption in critical control scenarios such as pressure and level regulation.

FAQ

Q: What is the purpose of the triple-input logic in these modules?
A: It ensures reliable control by validating three input signals and maintaining operation even if one signal fails.

Q: Are these modules compatible with modern Foxboro systems?
A: Yes, they are designed to integrate with both I/A Series and Evo DCS platforms.

Q: What communication interfaces are available?
A: RS-232 and RS-485 interfaces are supported for industrial communication.

Q: Can these modules operate in harsh environments?
A: Yes, they are designed for high vibration, electrical noise, and wide temperature ranges.

Q: How do these models differ from standard PLC modules?
A: They include built-in multi-input validation logic and are optimized for DCS-based redundant control systems rather than standalone PLC applications.
