GEYA 1 Output Delay ON Time Relay GRT6-A1

GRT6-A1 offers a Delay ON function with a companion GRT6-B for Delay OFF. It provides direct panel knob adjustment for quick setup and a broad time scale from 0.1 seconds up to 10 days, split across several ranges. The unit is designed for DIN rail mounting and supports AC/DC 24–240V. This configuration suits applications requiring controlled power-on sequencing after a preset delay, such as machine startups or process timers. Use the time-range and function selector to tailor the delay to your system requirements.
Delay On Time Relay GRT8 A1 16A (IGEYAPA)

This 12V timer relay provides a wide delay range from 0.1 seconds to 10 days with an operating voltage of AC/DC 24–240V and a 16A rating. Output is SPDT (1NO, 1NC). An LED indicator shows power status and timing activity, aiding quick calibration. It supports Delay ON and can be used to precisely delay equipment start-ups or lighting changes. Operators can set delay values by adjusting two knobs and verifying via the LED indicators, with attention to the model variants for specific ON/OFF behavior.
Baomain 16A DIN Rail Timer Relay (TBT7-C1)

The Baomain TBT7-C1 offers a 16A SPDT output with 0.1 s to 10 days timing and a wide voltage range of 12–240V AC/DC. It is designed for DIN rail mounting and provides a robust option for various control circuits, including motors, heaters, and lighting. The device emphasizes a compact form factor and reliable switching performance across a broad voltage range, with straightforward configuration for Delay ON or Delay OFF tasks.
IGEYAPA GRT8-M1 Multifunction Time Relay

GRT8-M1 provides multiple timing functions controlled by power supply voltage and control input, including a latching option. The 12–240V AC/DC range and 16A rating support diverse control schemes, with a timing window from 0.1 seconds to 10 days. It uses a 1SPDT output and includes LED indicators to reflect power, operation, and stop states. This relay is suited for complex sequences such as asymmetric cycling (OFF-ON-OFF or ON-OFF-ON) and multi-mode timing, enabling precise automation scenarios where multiple delays are needed from a single device.
Baomain TBT7-C1 16A Multi-Function Time Relay

This multi-function timer relay combines 0.1 s to 10 days timing with a 1SPDT contact and a 12–240VAC/DC voltage range. It supports various delay modes, including power-on delay, disconnection delay, and cyclic timing. The device uses a compact DIN rail footprint with a robust housing and provides indicators to assist with configuration. It is appropriate for controlling motors, heaters, or lighting circuits that require precise start or stop timing within broader automation systems.
Buying Guide: Key Considerations for Time On Delay Relays
- Timing range and steps: Determine whether you need 0.1 s resolution, milliseconds, or days. Look for relays offering broad ranges (0.1 s to 10 days) and clear time scales.
- Voltage compatibility: Ensure the relay supports your control system voltage (AC, DC, and common voltages like 12V, 24V, 110V, or 240V). Battery-powered or mixed-voltage environments may require AC/DC compatibility.
- Contact configuration: Choose SPDT (1NO 1NC) for flexibility, or SPST if a simple on/off is sufficient. Consider current rating (8A, 10A, 16A, etc.) based on load.
- Function modes: Decide between Delay ON, Delay OFF, or multifunction models. Some relays offer asymmetric cycling and latching options for complex sequences.
- Mounting and form factor: DIN rail mounting is common in control panels. Confirm housing durability and compatibility with existing enclosures.
- Indicators and usability: LED indicators help monitor power and timing status. User-friendly knobs or dip switches can simplify setup.
- Reliability and standards: Check UL CE RoHS compliance and build quality to ensure long-term performance in industrial settings.
- Integration considerations: Review whether the relay supports external controls or programmable inputs for precise synchronization with other equipment.
- Applications: Consider whether your use case is motor control, lighting automation, temperature control, or process sequencing to select the most appropriate timing profile.
