Digital Output 24VDC
Function
The Digital Output bussed 24VDC (DO24V) module can switch reliable 24V digital output signals to control otherprocess equipment as well as solenoid valves and interposing relays.
Notable Features
• Extensive internal diagnostics to ensure dataintegrity • Optional redundancy • Safe-state (FAILOPT) behaviors • Direct/Reverse output support • Latched, pulsed or pulse-width modulatedoutput (per channel) • Galvanic Isolation
Bussed 24VDC DO
The Digital Output Bussed 24VDC has provisions for both internal and external field power excitation. As a bussedoutput device, all of the outputs share a common return (ground). All outputs get their power from the same source,which can be either the system power supply or an externally connected 24V power supply. When selection is froman external source, outputs can be galvanically isolated from the Series 8 power system.
Safe-state Behavior (FAILOPT)
Series 8 DO module will support FAILOPT parameter on a per channel basis. The output can be directed byconfiguration to either HOLD THE LAST VALUE, or SHED to a SAFE VALUE. The safe value can be configured bythe user.
Installation & Maintenance Guidelines
Installation Steps:
Ensure Compatibility: Verify that the module is compatible with your Honeywell control system.
Mounting: Securely install the module in the designated rack slot.
Wiring: Connect output devices using shielded cables to prevent signal interference.
Power Connection: Ensure the module is properly connected to a 24V DC power supply.
System Configuration: Use Honeywell's software tools to configure the output channels as per application requirements.
Testing: Perform functional tests to confirm proper operation before deploying in a live system.
Maintenance Tips:
Regular Inspection: Periodically check wiring connections for any signs of wear or damage.
Firmware Updates: Keep system firmware updated for optimal performance and security.
Environmental Considerations: Ensure the module is operating within the recommended temperature range (-20°C to +60°C).
Fault Diagnostics: Utilize built-in diagnostic tools to detect and troubleshoot potential issues early.
