2Pcs Delay On Make Timer, 0.03–10 Min, 19–288 VAC/DC
The Weasch Store 2Pcs Delay On Make Timer provides adjustable delays from 0.03 to 10 minutes and supports a wide input range of 19–288 VAC or DC, with 50/60 Hz line frequency. This makes it suitable for simpler automation tasks where a compact, dual-timer solution is needed. Best for: small machines or circuits that require a lightweight, adjustable delay on power-on, especially when operating on variable AC/DC supplies. Caution: verify that the control voltage and load current stay within the device’s rated specifications, as data focuses on time ranges and voltage bands rather than high-current applications.
Key specifications and practical notes:
– Adjustable time: 0.03–10 minutes
– Input voltage: 19–288 VAC or VDC
– Line frequency: 50/60 Hz
– Package: two units in one package for easy installation
GRT6-M1 Multifunction Time Delay Relay, 24–240V AC/DC
The GRT6-M1 is a multifunction time delay relay with 10 A rated load and a wide delay range from 0.1 seconds up to 10 days. It supports AC 24V–240V and includes five time functions controlled by power supply and four functions controlled by control input, plus a latching option. Best for: DIN-rail automation panels needing versatile timing modes (power-on delay, delayed disconnection, and cyclic delays). Why selected: broad delay spectrum and clear LED indicators help operators monitor status. Caution: some users may need to thoroughly review function mappings (A–F, E) to select the exact delay mode for a given application.
Key features:
– Wide delay setting: 0.1 s to 1 minute to 10 days
– Output: 1 SPDT (1 NO, 1 NC)
– Indication: LED status indicators
– Housing: ABS shell for durability
– Compliance notes: UL, CE, CB, RoHS referenced in product data
GRT6-M1 AC/DC 24–240V Time Relay, 24–240V Operation
This multifunction GRT6-M1 time relay supports a wide 24–240V range and offers a similar 0.1 s to 10 days delay window as the previous model, with 10 A rating. Best for: integrated control of lighting, heating, or motor loads in a DIN-rail panel where multiple timing patterns are needed. Choose this if your project benefits from the same GRT6 family family features (A–F modes) but requires a slightly different instruction set and LED behavior. Limitation: the detailed function mapping must be reviewed to ensure the exact mode aligns with the intended delay pattern.
Why it stands out:
– Similar core specs to the M1 variant, making it easy to swap in a panel design
– Clear status LEDs assist in quick fault diagnosis during setup
– Suitable for industrial equipment and lighting control
Delay Off Time Relay GRT6-B1 10A, 0.1s–10 Days
The GRT6-B1 is a 10A delay-off relay suited for turning devices off after a set period. It covers a broad range from 0.1 seconds to 10 days and accepts AC/DC 24–240V. Best for: systems requiring a defined shutdown window after activation, such as fans or signaling devices that must shut down after a timed interval. Limitation: as a dedicated delay-off model, ensure your circuit’s logic matches a timer-on-before-off sequence rather than delay-on applications.
What makes it useful:
– Delayed turn-off function with 10A capacity
– Wide voltage compatibility (AC/DC 24–240V)
– Clear light indicators to signal operating state
Delay On HYCRT8-A1 0.1sec-10day AC/DC 24-240V
The HYCRT8-A1 offers a 0.1-second to 10-day delay window with a broad operating range of 24–240V AC/DC. It’s designed for DIN rail mounting and includes a flame-retardant shell with a built-in indicator and an adjustable time panel. Best for: installations needing a compact 24V timer with a quick start and long-delay capability. Caution: validate the preset time alignment, since the setup relies on knob adjustments that must be read against the specific timing function required (e.g., power-on delay vs. delay open/close).
Why to choose this:
– Small form factor with DIN rail compatibility
– Wide delay range supports diverse automation tasks
– Robust shell and integrated indicators for ease of use
Buying Guide: Key Considerations For Your Time Delay Relay Purchase
What delay range do you need?
Delay ranges vary from fractions of a second to several days. Identify the minimum and maximum delays your application requires and select a model that covers that window without overshooting the needed time.
What voltage and load can you support?
Most 24V relays support AC/DC ranges such as 24–240V. Confirm the supply type in your system (AC or DC) and ensure the relay’s output can handle your load current. If you’re driving motors or heaters, prioritize models with higher current ratings (e.g., 10A) and verify whether the output is SPDT (NO/NC) to match your circuit design.
Which features are essential?
Consider whether you need a latching function, multiple timing modes (delayed power-on, delayed disconnection, cyclic delay), or an indicator LED for status. Some models provide multiple operation modes (A–F) in one unit, which can simplify complex automation schemes.
DIN rail mounting and enclosure considerations
For panel installations, DIN-rail compatible relays in ABS or flame-retardant housings are preferred. Ensure the housing material and mounting method fit your enclosure and offer protection in your environment.
Indicator and maintenance considerations
LED indicators help during setup and troubleshooting. Look for clear, visible indicators that show power status and timing progress, reducing cross-check effort in maintenance windows.
Frequently Asked Questions
- What is a time delay relay for 24V systems? A time delay relay is an electronic switch that turns a circuit on or off after a preset delay, with compatibility for 24V AC or DC supply in many models.
- How do I choose between delay-on and delay-off relays? Delay-on relays start the delay after power is applied, while delay-off relays complete the delay before turning off the circuit. Choose based on whether you need a delayed start or a timed shutdown pattern.
- Can these relays control motors or heaters? Yes, but verify the load current rating (often 10A) and ensure the relay’s contacts can handle inductive loads and inrush currents typical of motors or heaters.
- Are LED indicators reliable for fault detection? LED indicators provide quick status feedback, but for critical applications you should combine indicators with proper wiring diagrams and, if needed, external sensors to confirm operation.
- What installation considerations are essential? Use DIN-rail mounting where appropriate, ensure proper wire sizing, and verify the device’s voltage and timing settings before powering the circuit.
- Do these relays require programming? Most multipurpose relays require selecting the function mode (A–F) and setting the delay with dials or jumpers; consult the product instructions for exact steps.
