MeloAuto-Trusted PLC & DCS Parts Supplier
General Overview
- Model Number: CC-TDOD51 (Non-Redundant, 9″)
- Alternate Model Number: CC-TDOD61 (Redundant, 12″)
- Product Name: Digital Output Bussed 24VDC (DO24V) Module
- Manufacturer: Honeywell
Functionality
The CC-TDOD51 Digital Output Bussed 24VDC (DO24V) module is designed to control process equipment, such as solenoid valves and interposing relays, by switching reliable 24V digital output signals.
Notable Features
- Comprehensive Internal Diagnostics: Ensures data integrity.
- Optional Redundancy: Supports non-redundant (CC-TDOD51) and redundant (CC-TDOD61) configurations.
- Electronic Overcurrent Protection: Prevents damage from current surges.
- Configurable Safe-State (FAILOPT): On failure, the output can be set to either hold the last value or switch to a safe value, configurable per channel.
- Output Types: Supports latched, pulsed, or pulse-width modulated output on each channel.
Bussed 24VDC Output Details
The Digital Output Bussed 24VDC module supports both internal and external field power excitation:
- Shared Common Ground: All outputs share a common return.
- Power Source Options: Outputs can be powered either by the system power supply or an external 24V power supply.
- Galvanic Isolation: External power source can provide isolation from the Series C power system.
- IOTA Wiring Option: Determines if outputs reference the Series C system power or an external field power source.
FAILOPT (Safe-State) Configuration
- Per Channel Basis: FAILOPT can be set individually for each channel.
- Options:
- Hold Last Value: Retains the last output value on failure.
- Shed to Safe Value: Switches to a predefined safe value (user-configurable).
