TS Relay Overview:

The TS Relay is a specialized relay with built-in timing functions. It provides adjustable timing delays without the need for auxiliary voltage for delay functionality. It's capable of various timed operations, including delayed activation (attraction), delayed release (retombée), flashing operation (clignotant), and brief impulse contacts (contact bref). External timing adjustments (temporization) are possible, making this relay highly flexible for timing-dependent applications.

Mechanical Characteristics:

• Dimensions: 34 mm × 34 mm × 10.8 mm

• Form Factor: Compact square form with PCB mounting pins.

Contact Configurations Available:

• 2T2R: Two Normally Open (NO) + Two Normally Closed (NC) contacts.

• 3T1R: Three Normally Open (NO) + One Normally Closed (NC) contact.

• 4T: Four Normally Open (NO) contacts.

Switching Capabilities:

• Switching Power (W/VA):

  • Min: 10⁻¹⁰ W (ultra-low signal levels)

  • Max: 100 W DC / 1000 VA AC (resistive loads)

• Switching Voltage (VDC/VAC):

  • Hold Current: 5 A (continuous current rating)

  • Break Current: 5 A (maximum current interrupting capability)

• Contact Resistance:

  • Typical initial contact resistance: 10–30 mΩ

Timing Characteristics:

• Timing Range (Adjustable):

  • From 0.1 s up to 800 s (approx. 13 minutes)

  • Timing functions operate without external power supply for the delay feature, simplifying system design.

• Timing Functions Available:

  • Delayed activation (attraction delay)

  • Delayed release (drop-out delay)

  • Flashing operation (repeated cycles of ON/OFF)

  • Brief impulse contact operations

• External Adjustment:

  • Timing delay can be adjusted externally, typically via external resistor or timing components.

Coil Characteristics:

• Operating Mode:

  • Monostable (relay returns to default state upon coil de-energization)

• Number of Coils:

  • Single coil operation

• Coil Voltage Options:

  • Common coil voltages available: 5 V, 12 V, 24 V DC

• Power Consumption (Coil at 12 V):

  • 200–300 mW, depending on specific coil option.

Environmental and Reliability Data:

• Operating Temperature Range:

  • -20°C to +85°C

• Shock and Vibration Resistance:

  • Rated: 50 g shocks and vibration resistance at frequencies 20–1000 Hz

• Dielectric Strength (Insulation):

  • Contact-to-coil isolation: 750–1500 V effective

• Protection Rating:

  • IP50 protection rating, suitable for standard indoor conditions (PCB mount).

• Mounting Method:

  • PCB mounting (CI for "circuit imprimé").

Compliance & Efficiency:

• Agency Approvals:

  • No specific approvals listed in datasheet excerpt provided.

• Efficiency ηL (performance measure indicating relay effectiveness relative to size/power):

  • Rated: 1600, indicating very good efficiency relative to its compact size and capability.

Typical Applications:

• Automation systems requiring precise timing sequences.

• Industrial control systems for delayed activation/release scenarios.

• Signaling or blinking applications (alarms, indicators).

• Systems requiring compact, reliable timed switching without auxiliary power.

Summary of TS Relay Key Features:

• Built-in, adjustable timing capability (0.1 to 800 seconds).

• Does not require auxiliary power for timing delays.

• Multiple timing functions in a single relay (delay on make/break, flashing).

• High switching capability (up to 100 W DC or 1000 VA AC).

• Compact PCB-mount relay with flexible contact configurations (2T2R, 3T1R, 4T).

• Suitable for general-purpose timing applications in industrial automation and electronic equipment.
