P0926KL
Product Name
Foxboro (by Schneider Electric) P0926KL Redundant Digital I/O Module for I/A Series DCS(The naming follows Foxboro’s DCS module conventions:
-
-
- “P0926KL”: Identifies the “P0926” series of I/O modules, with “KL” specifying the redundant digital I/O variant (distinguished from P0926KP (digital input) and P0926KE (mixed I/O)).
- “Redundant Digital I/O Module”: Highlights its dual core functions—redundant hardware for fault tolerance and integrated digital input/output capabilities for process control.
This module acts as a “process signal hub,” ensuring uninterrupted monitoring of digital sensors (e.g., switches) and control of actuators (e.g., valves) while eliminating single points of failure in industrial systems.)

2. Product Description
The P0926KL is an industrial-grade redundant digital I/O module engineered by Foxboro (now part of Schneider Electric) to address core challenges in process automation: signal acquisition failure, output control downtime, and unreliable operation in harsh environments. As a key component of Foxboro’s I/A Series DCS, it integrates dual-channel redundancy, electronic fault protection, and seamless DCS integration—making it indispensable for:
-
-
- Oil & Gas Industry: Monitoring pipeline valve positions and controlling pump starters, where downtime could lead to leakage or production losses.
- Chemical Processing: Tracking reactor pressure switch statuses and actuating emergency shutoff valves, ensuring compliance with safety regulations.
- Power Generation: Managing turbine auxiliary equipment (e.g., lubrication pumps) and monitoring generator breaker statuses, supporting stable grid supply.
- Water & Wastewater Treatment: Controlling filtration system valves and monitoring flow switch signals, maintaining consistent water quality 。

Key Functional Advantages
-
-
Dual-Channel Redundancy for Uninterrupted OperationEquipped with redundant power supplies and communication channels that operate in hot-standby mode 。 If the primary channel fails (e.g., wiring fault, component malfunction), automatic failover activates within milliseconds—ensuring continuous signal transmission to the DCS 。 This redundancy reduces unplanned downtime by >99% compared to non-redundant modules 。
