Product Overview

The Woodward 5462-408 functions as a high-density Discrete Input module within the MicroNet Digital Control System architecture. This module captures and conditions 32 independent contact signals from field equipment, such as limit switches, breaker status contacts, and safety interlocks. By converting these 24V DC field signals into digital data for the MicroNet CPU, the 5462-408 enables real-time logic processing and sequence-of-events monitoring. It provides the essential feedback loop required for the safe operation of gas turbines, steam turbines, and large-scale industrial engines.

Condition: This product is 100% Brand New, Original Woodward factory stock, and currently available for immediate dispatch.

Engineering Advantages

High-Density Signal Management: Integrating 32 inputs into a single card slot maximizes the utilization of the MicroNet chassis. This high-density layout reduces the number of required I/O racks, lowering overall system costs and cabinet footprint.
Superior Galvanic Isolation: Advanced optical isolation barriers protect the central control logic from field-side transients, ground loops, and accidental overvoltages. This ensures that a single field wiring fault does not compromise the entire control system.
Optimized Thermal Endurance: The module operates across an expansive temperature range (-40°C to +85°C). This allows for reliable installation in unconditioned control rooms or turbine-mounted enclosures where thermal fluctuations are common.
Real-Time Visual Diagnostics: Dedicated front-panel LEDs for every channel provide instantaneous feedback on input status. Technicians can verify field contact closure without using a multimeter, significantly accelerating commissioning and troubleshooting.
Deterministic Logic Processing: The 5462-408 maintains high-speed response times suitable for critical safety interlocks and protection functions, ensuring the control system reacts immediately to process changes.

FAQs

Can the 5462-408 handle 125VDC or 120VAC field signals?

No. The 5462-408 is specifically designed for 24VDC nominal signals. To interface with higher voltage signals, you must use interposing relays or choose a Woodward module specifically rated for higher voltage inputs.
Does this module support "Sequence of Events" (SOE) recording?

Yes. When used within a MicroNet system configured for SOE, the 5462-408 provides the fast-response inputs necessary to time-stamp state changes with millisecond precision for post-trip analysis.
Is the 5462-408 a direct replacement for older MicroNet discrete input cards?

This module follows the standard MicroNet VME architecture. While it often serves as a direct replacement, always verify your system's Field Terminal Module (FTM) compatibility and software configuration before swapping hardware.
How does "Positive Logic" affect my field wiring?

In a positive logic configuration, the input channel registers an "ON" state when 24VDC is applied to the input terminal relative to the common. This is the most common configuration for industrial safety and control circuits.
