Woodward 8280-423 Distributed I/O Module
Manufacturer: Woodward
Product Number: 8280-423
Category: High-Density Distributed I/O Module
Series: Woodward 8000 series
Application: Mission-critical control systems in power generation, oil & gas, and industrial automation requiring rugged distributed I/O
Product Description
The Woodward 8280-423 is a high-density distributed I/O module designed for mission-critical control systems in power generation, oil & gas, and industrial automation applications. As part of Woodward’s 8000 series of rugged control components, this advanced module provides 32 channels of configurable analog/digital I/O with galvanic isolation and ±0.05% accuracy. The 8280-423 features dual-redundant EtherCAT® communication with ≤100µs cycle times, enabling precise synchronization in distributed control architectures. Its stainless steel IP67 enclosure withstands harsh environments (-40°C to +85°C operating temperature, 5G vibration), while hot-swappable design allows for maintenance without system shutdown. With embedded signal conditioning and predictive diagnostics, the Woodward 8280-423 delivers reliable data acquisition and control for turbine management, compressor stations, and other critical processes.
Technical Specifications
| Parameter Name | Parameter Value |
| Product Model | 8280-423 |
| Manufacturer | Woodward |
| Product Type | Distributed I/O Module |
| Channels | 32 (universal configurable) |
| Input Types | 0-10V, 4-20mA, TC, RTD, DI (24V) |
| Output Types | 0-10V, 4-20mA, DO (2A) |
| Isolation | 1500V channel-to-channel |
| Accuracy | ±0.05% (analog), ±1µs (digital) |
| Communication | Dual EtherCAT® (100Mbps) |
| Update Rate | 100µs (synchronized) |
| Power Supply | 24V DC (18-36V) |
| Power Consumption | 8W typical |
| Operating Temp. | -40°C to +85°C |
| Protection Rating | IP67 (NEMA 6) |

Universal channel configurability: Each of the 32 channels on the Woodward 8280-423 can be individually programmed as analog input/output, digital input/output, or temperature input via software – no hardware changes required. This flexibility reduces spare parts inventory and simplifies system expansion.
Deterministic performance: The module’s EtherCAT® interface delivers ≤100µs cycle times with ≤1µs jitter, synchronized across distributed nodes via DC (Distributed Clocks). Dual ports enable daisy-chain topology without switches, reducing cabling and failure points.
Advanced diagnostics: Built-in channel-level health monitoring detects open wires, shorts, and out-of-range conditions. The 8280-423 provides predictive failure alerts for components like power supplies and optocouplers based on performance trends.
Ruggedized design: Featuring conformal-coated PCBs and gold-plated connectors, the module survives harsh conditions including humidity, dust, and chemical exposure. Its -40°C cold start capability ensures reliable operation in arctic environments.
The Woodward 8280-423 is ideal for:
Turbine Control Systems: High-speed vibration monitoring and valve positioning
Compressor Stations: Anti-surge control with fast pressure/flow measurements
Marine Power Management: Distributed I/O for engine room automation
Process Industries: Batch control with precise temperature monitoring
Renewable Energy: Hydraulic pitch system control for wind turbines
Installation and Maintenance
Pre-installation preparation: Verify EtherCAT® network topology and configure node addresses before power-up. Use shielded twisted pair cables for analog signals with single-point grounding.
Maintenance recommendations: Perform annual calibration verification using Woodward’s IO-Check™ software. Clean connector seals every 6 months in dusty environments. Monitor channel drift statistics via embedded diagnostics. The 8280-423 supports hot-swapping in redundant configurations.
Product Guarantee
Woodward provides a 5-year warranty covering all components including connectors. Each module undergoes:
500-hour burn-in testing with thermal cycling
Full channel-by-channel validation
NIST-traceable calibration
The Platinum Support Program includes:
24/7 technical assistance
Lifetime firmware updates
10-year spare parts availability
On-site calibration services
