Description

Product Overview：8273-140

The WOODWARD 8273-140 represents a high-performance I/O module designed for mission-critical industrial automation systems. As part of Woodward’s ProTech series, this robust module serves as a cornerstone in distributed control architectures, enabling precise signal conditioning and data acquisition for turbines, generators, and rotating machinery. The WOODWARD 8273-140 integrates 16 analog/digital channels with galvanic isolation, making it ideal for environments requiring noise immunity and signal integrity.

Engineered for Woodward’s safety instrumented systems (SIS), the WOODWARD 8273-140 operates seamlessly with third-party PLCs and DCS platforms, offering configurable fail-safe logic through its embedded microprocessor. Its modular design allows hot-swapping in redundant configurations, minimizing downtime in power generation and oil/gas applications. The module’s MIL-STD-810G compliance ensures reliable operation under extreme temperatures (-40°C to +85°C) and mechanical stress, positioning the WOODWARD 8273-140 as a trusted component in Tier 4 data centers and offshore platforms.

Key Features and Advantages：8273-140

Signal Integrity: The WOODWARD 8273-140 employs 16-bit ADCs with <0.01% FSR nonlinearity, achieving ±0.05% accuracy across all analog inputs. Its active noise cancellation technology eliminates ground loops in distributed systems.

Redundancy Support: Dual hot-swappable power inputs and mirrored communication ports enable seamless transition between primary/secondary controllers, critical for turbine overspeed protection systems6.

Diagnostic Depth: Onboard health monitoring tracks parameters from connector mating cycles (500+ guaranteed) to capacitor aging, with predictive maintenance alerts via Woodward’s Asset Sentinel software.

Legacy Compatibility: The module’s universal terminal blocks accept screw-in or spring-clamp connections, backward-compatible with Woodward 8270/8280 series field wiring.
