Digital Output - Bussed 24VDC – CC-PDOB01

Function: The Digital Output Bussed 24VDC (DO24V) module delivers dependable 24V digital output signals, facilitating the control of process equipment, solenoid valves, and interposing relays with precision. Its support for high-energy outputs reduces the need for external components in the output loop.

Notable Features:

• Extensive Internal Diagnostics: Ensures data integrity through continuous monitoring.
• Optional Redundancy: Enhances reliability through redundant configurations.
• Direct/Reverse Output Support: Provides flexibility in output configuration for various applications.
• Safe-state (FAILOPT) Behaviors: Configurable on a per-channel basis to HOLD THE LAST VALUE or SHED to a SAFE VALUE.
• "Fuse-less" Short Circuit Protection: Detects and handles short circuits without blowing fuses, ensuring uninterrupted operation.
• Latched, Pulsed, or Pulse-width Modulated Output (Per Channel): Offers versatile output modes to suit different requirements.
• Galvanic Isolation: Provides electrical isolation for safety and system integrity.

Bussed 24VDC DO: The Digital Output Bussed 24VDC supports both internal and external field power excitation. All outputs share a common return (ground), drawing power from either the system power supply or an externally connected 24V power supply. When utilizing an external source, outputs can be galvanically isolated from the Series C power system.

Fuse-less Short Circuit Protection: This feature allows short circuits to exist without blowing any fuses. Internal circuits detect a short on a channel, removing power to the field connection. The channel remains de-energized until the short circuit is resolved.

FAILOPT: The Series C DO module supports the FAILOPT parameter on a per-channel basis, enabling users to configure output behavior according to their needs.
