FOXBORO 269P-D_O-241-100P-HI 24-Channel Digital Output Module for I/A Series DCS

Application Scenarios

In a large petrochemical refinery in Saudi Arabia,operators struggled with frequent failures in legacy digital output modules controlling critical valve actuators.The old cards lacked diagnostic feedback,leading to extended downtime during fault isolation.Engineers replaced them with the 269P-D_O-241-100P-HI,leveraging its per-channel LED status indicators and built-in short-circuit protection.Within weeks,mean time to repair dropped by 70%.When a solenoid short occurred,the 269P-D_O-241-100P-HI immediately isolated the fault and illuminated the corresponding LED,allowing technicians to pinpoint the issue without shutting down the entire rack.In power plants,water treatment facilities,and LNG terminals,the 269P-D_O-241-100P-HI continues to serve as a trusted workhorse—ensuring precise,safe,and maintainable control signal distribution across mission-critical processes.

Technical Principles and Innovative Values

Innovation Point 1:Dual-Mode Output Flexibility

The 269P-D_O-241-100P-HI supports both sourcing(positive switching)and sinking(negative switching)modes,allowing seamless integration with a wide range of field devices—whether NPN sensors from Asian suppliers or PNP devices from European OEMs—without requiring external relays or signal converters.

Innovation Point 2:Per-Channel Diagnostics with LED Feedback

Unlike generic output modules,each of the 24 channels features an individual green LED that lights when the output is energized.This visual feedback drastically reduces troubleshooting time,enabling technicians to verify signal integrity at a glance—critical during commissioning or emergency response.

Innovation Point 3:Robust Electrical Isolation Architecture

With≥1500 VAC isolation between channels and from channel to ground,the 269P-D_O-241-100P-HI prevents ground loops and suppresses electrical noise in high-interference environments like motor control centers or high-voltage switchyards,ensuring signal integrity and system stability.

Innovation Point 4:Hot-Swappable Design with Terminal Base Compatibility

The module snaps into the FBM127/FBM128 terminal base,allowing hot replacement without disconnecting field wiring.This design minimizes process downtime during maintenance—a key advantage in continuous operations such as oil refining or power generation.

Application Cases and Industry Value

At a coal-fired power plant in India,the turbine bypass system relied on digital outputs to trigger dump valves during load rejection events.Frequent module failures due to voltage transients caused delayed responses,risking turbine damage.After upgrading to the FOXBORO 269P-D_O-241-100P-HI,the plant experienced zero output-related failures over 24 months.The solid-state design with surge protection and fast response time(<2ms)ensured valves opened within milliseconds,improving safety and reducing equipment stress.Operators reported a 90%reduction in I/O-related maintenance tickets.

In a desalination plant in Egypt,the 269P-D_O-241-100P-HI was deployed to control anti-scaling dosing pumps.The per-channel LEDs allowed operators to visually confirm pump activation sequences,eliminating misfires.The module’s 100mA drive capability handled the solenoid valves directly,reducing component count and wiring complexity.The plant extended its mean time between failures(MTBF)by over 300%,contributing to uninterrupted water production.

Installation,Maintenance,and Full-Cycle Support

Installing the 269P-D_O-241-100P-HI is fast and tool-free:align the module with the FBM127/FBM128 terminal base and press firmly until it clicks into place.The module automatically configures upon power-up and is recognized by the I/A Series controller.Field wiring is pre-terminated on the base,so no rewiring is needed during replacement.The front-panel LEDs provide instant confirmation of power and channel status,accelerating commissioning and reducing human error.

Routine maintenance is minimal due to the solid-state design and absence of moving parts.However,periodic inspection of terminal screws and environmental conditions(dust,humidity)is recommended.The module’s short-circuit and overcurrent protection prevent cascading failures.In the event of a fault,the 269P-D_O-241-100P-HI can be replaced in under 5 minutes,ensuring maximum process availability.We provide full technical support,including wiring diagrams,compatibility checks,and lifecycle management for legacy FOXBORO systems.
