Woodward 5466-316 Digital I/O Module

Discrete Inputs: 48 channels (typical configuration), supporting dry or wet contact signals.

Discrete Outputs: 24 channels (typical configuration), with optional relay or transistor outputs.

Isolation Feature: Optical isolation between input/output channels for strong anti-interference capability.

Power Supply: 24VDC ±15%, with optional redundant power support.

Power Consumption: <15W (typical value).

Signal Levels:

Operating Temperature: -20°C to +60°C (standard type); extended type up to -40°C to +85°C.

Humidity: 5-95% relative humidity (non-condensing).

Protection Rating: NEMA 4X/IP65 (requires a protective enclosure).

Main Communication: Supports protocols such as Modbus RTU/ASCII, EtherNet/IP, and PROFIBUS DP.

Auxiliary Interface: RS-232 port for configuration and diagnostics.

Integrates 48 inputs and 24 outputs, saving control cabinet space and suitable for complex system applications.

Supports hot-swapping, allowing online module replacement without affecting system operation.

Channels can be independently configured for different functions (e.g., digital input, pulse counting, status indication, etc.).

Built-in watchdog timer ensures safe shutdown under abnormal conditions.

Fail-Safe outputs: Configurable default output states during power loss.

Channel-level fault detection with LED status indication and remote alarm support.

Event log records the latest 100 fault messages for traceability and analysis.

Receives external discrete signals (e.g., switch states, relay contacts) via opto-isolation circuits and converts them to digital quantities.

Supports high-speed counting (e.g., rotational speed pulse acquisition) with a maximum frequency of 10kHz.

The microprocessor filters and debounces input signals, comparing them with preset thresholds.

Supports logical operations (AND, OR, NOT) and timing functions (delayed triggering, pulse width measurement).

Outputs control signals via relays or transistors based on processing results.

Outputs can be configured in latching or pulse mode to adapt to different actuator requirements.

Transmits I/O status to controllers or host computers in real time via industrial buses.

Supports remote configuration and firmware upgrades to simplify system maintenance.

Start/stop control and protection interlocks for steam/gas turbines.

Logic control for generator synchronizing and grid connection.

Compressor anti-surge control and Emergency Shutdown Systems (ESD).

Valve position feedback and remote operation.

Sequential control for start/stop of large motors.

Process interlocks and safety barrier interfaces.

Condition monitoring and control of main propulsion systems.

Emergency Shutdown systems.
