SWAN Electric CODT Series Pneumatic On-Delay Timers (CODT-CO-DEL-30S & CODT-CO-DEL-180S).

• The SWAN Electric CODT series pneumatic timer delays are robust front-mounting accessories designed to add precise on-delay timing functionality to SWAN AC contactors and contactor relays.
• These units provide a reliable method to connect or disconnect a circuit after a predetermined time has elapsed once the main contactor is energized.
• Available in two distinct adjustable time ranges, 0.1-30 seconds (CODT-CO-DEL-30S / CODT2) and 10-180 seconds (CODT-CO-DEL-180S / CODT4), these timers feature 1 Normally Open (NO) + 1 Normally Closed (NC) contacts, making them versatile for a wide array of industrial control and automation applications.

Features

• Adjustable On-Delay Timing: Allows for precise setting of the delay period before the auxiliary contacts change state.
• Two Time Range Options:
  • CODT-CO-DEL-30S (CODT2): 0.1 to 30 seconds, offering fine control for shorter delays.
  • CODT-CO-DEL-180S (CODT4): 10 to 180 seconds, suitable for applications requiring longer delay periods.
• Contact Configuration: Each unit provides 1 Normally Open (NO) and 1 Normally Closed (NC) timed contacts.
• Front Mounting Design: Easily attaches to the front of compatible SWAN AC contactors, saving panel space.
• Screw Clamp Terminals: Ensures secure and reliable electrical connections for control wiring.
• Pneumatic Operation: The timing mechanism is pneumatic, requiring no separate electrical control voltage for the timer function itself; it operates based on the mechanical action of the contactor.
• IEC 60947-5-1 Compliant: Meets international standards for low-voltage switchgear and controlgear, specifically for control circuit devices and switching elements.
• Clear Time Setting Dial: Features an easy-to-read dial for accurate adjustment of the delay time.

Benefits

• Automated Sequential Control: Enables the creation of timed sequences in control circuits, such as staggered motor starting or delayed process activation.
• Enhanced Process Efficiency: Precise timing helps optimize industrial processes and improve operational efficiency.
• Versatile Application: With two distinct time ranges and NO/NC contacts, these timers can be adapted to a broad spectrum of control needs.
• Easy Integration: Simple front-mounting design allows for quick and straightforward installation onto compatible contactors.
• Reliable Performance: Robust construction and compliance with IEC standards ensure dependable operation in industrial environments.
• Cost-Effective Automation: Provides a simple and economical solution for adding timed control without complex electronic relays.

In-Depth Technical Specifications

Ideal Use

• Implementing timed sequences in motor control, such as star-delta (wye-delta) starting.
• Staggered starting of multiple motors or loads to reduce inrush current.
• Control of automated machinery where processes need to occur after a specific delay.
• Timed activation or deactivation of alarms or signals.
• General industrial automation tasks requiring precise on-delay functionality.
• HVAC systems for timed fan operation or sequencing.

Tips

• Select Correct Time Range: Choose the model (30S or 180S) that best covers the required delay time for your application, allowing for some adjustment margin.
• Accurate Time Setting: Carefully set the desired delay time using the adjustment dial. Verify the setting before putting the system into full operation.
• Ensure Contactor Compatibility: Verify that the CODT timer is compatible with the specific SWAN contactor model it will be mounted on.
• Secure Mounting: Ensure the timer block is firmly and correctly latched onto the contactor for reliable mechanical operation.
• Wiring: Use appropriate wire gauges for the control circuit (up to 10A Ith for the contacts) and ensure all screw clamp terminals are securely tightened.
• Understand On-Delay Function: Remember that with an on-delay timer, the timing period begins when the main contactor coil is energized. The auxiliary contacts change state only after the set delay has elapsed (while the contactor remains energized).
