Foxboro|FBM241 P0914TG|Discrete I/O Module

Description
The Triconex FBM241 (P0914TG) is a discrete I/O module for the Foxboro™ DCS, providing 8 isolated input and 8 isolated output channels for low/high-voltage signals (15–60VDC, 120VAC/125VDC, or 240VAC).

Features

• 8 inputs + 8 outputs, each galvanically isolated.
• Supports mixed signal types (DC/AC, low/high voltage).
• Configurable filter/debounce time (0–32ms).
• Rugged Class G3 design for harsh environments.
