Functionality
The 8C-PDOD51 Digital Output Module is designed for bussed 24VDC systems, providing precise control of solenoid valves, interposing relays, and other process equipment. Its flexible configuration allows it to adapt to various industrial applications, ensuring high reliability and safety.
Notable Features
- Extensive Diagnostics
- Built-in diagnostics continuously monitor system integrity and quickly identify issues.
- Redundancy Support
- Can pair with redundant IOTA modules to enhance system availability.
- Safe-State (FAILOPT) Behavior
- Each channel can HOLD THE LAST VALUE or SHED to a SAFE VALUE during failures.
- Users can customize the safe state for each channel.
- Output Flexibility
- Supports latched, pulsed, or pulse-width modulated outputs for versatile operation.
- Galvanic Isolation
- External user-supplied power provides system-to-field isolation for enhanced safety.
- Shared Power Design
- Outputs share a common return and can be powered by either the system supply or external 24V power.
