Description
Woodward PC104-DPIODRL-DPM-BKF
Technical Specifications
- Brand: Woodward
- Part Number: PC104-DPIODRL-DPM-BKF
- Form Factor: PC/104 Stackable Module
- I/O Type: Digital Input / Relay Output
Functional Features
- Optical Isolation: Provides galvanic isolation between field inputs and the PC/104 bus to protect against voltage spikes.
- Relay Outputs: Features robust relay contacts capable of switching higher current loads directly.
- Stackable Bus: Passes the PC/104 bus signals through to allow stacking of multiple modules without cables.
Application Scenarios
Used in embedded control panels, turbine auxiliary control systems, and remote monitoring units requiring discrete logic interfacing.
Performance Parameters
- Input Voltage Tolerance: Wide voltage acceptance for noisy industrial environments.
- Relay Life: High mechanical and electrical cycle rating for long-term reliability.
Material Composition
Industrial-grade PCB with gold-plated edge connectors, high-reliability relays, and optocouplers.
Structural Characteristics
Standard 90mm x 96mm PC/104 footprint with four corner mounting holes and 104-pin stack-through connectors.
Working Principle
Reads the state of field switches or sensors through isolated input circuits and writes to the relay output circuits based on commands from the host CPU module via the passive PC/104 bus.
Installation Requirements
Stack securely onto a compatible PC/104 CPU or base module. Ensure standoffs are used between modules to prevent short circuits.
Usage Precautions
Verify the voltage and current ratings of connected field devices do not exceed the module’s specifications. Provide flyback diodes for inductive loads.
