DC 24V Delay Timer Time Relay DPDT 0-60S (H3Y-2)
The H3Y-2 timer relay provides a DPDT contact arrangement powered by DC 24V. It supports a 60-second delay window and mounts on a 3.5 mm DIN rail. With eight terminals, it offers straightforward integration for compact control circuits and is suited for tasks requiring short, precise delays in automation or relay logic applications.
GRT6-M1 Multifunction Timer Relay, 24–240V
GRT6-M1 is a versatile timer relay with a broad input range (AC230V, 50–60 Hz) and a 24V DC option. It offers multiple timing functions—including power-on delay and latching modes—with a maximum load of 10 A. Indicators show power status and operation phases, aiding setup and troubleshooting in industrial equipment, lighting systems, and process control.
[2 Pack] DC 6-30V Timer Relay with LCD
This pair of timer relays supports DC operation from 6 to 30V with a micro USB 5V power supply. It features a wide timing range (0.1 seconds to 999 minutes) and a NO contact capable of handling up to 10 A at 250 VAC. The built-in diode provides reverse-polarity protection, which helps guard against incorrect wiring during installation in smart homes or small automation projects.
Baomain THC15A DC/AC 24V Digital LCD Timer
The Baomain THC15A timer is a 24V programmable switch with digital LCD readout and a 16 A contact rating. It supports full time ranges from 1 minute to 168 hours, and offers weekly or daily programming across up to 16 programmable periods. This makes it suitable for HVAC, lighting schedules, and machinery control requiring repeating schedules and precise timing.
Baomain DC 24V H3Y-2 Time Delay Relay
Baomain’s DC 24V H3Y-2 timer relay features DPDT contacts and a 30-second timing option, along with 8 terminals for DIN rail mounting. It is designed for compact installations where a short delay and a solid, DC-powered control relay are needed, such as small automation panels or DIY projects.
Weasch Timer Switch THC15A 24V, 16A
Weasch’s THC15A timer switch operates with a 24V DC/AC input and up to 16 A at 250 V AC. It supports up to 28 scheduled times daily or weekly, making it a robust option for more complex automation routines, irrigation, or building management systems that require multiple daily or weekly events.
Buying Guide: Key Considerations for 24V Timer Relays
- Voltage compatibility: Ensure the relay input and control voltage align with your system’s supply (DC 24V is common, but some units accept AC or mixed voltage ranges).
- Timing range and granularity: Look for the minimum and maximum delay settings that fit your application (seconds to days). If you need precise short delays, prefer relays with 0.1 s or smaller increments.
- Output contacts and load rating: Check the contact type (SPDT/DPDT) and the maximum current and voltage for the loads you’re switching (AC vs DC compatibility matters).
- Programming features: Some models offer fixed, adjustable, or multiple timing modes, including power-on delay, delayed off, or cyclic timing. LCD displays and indicators aid setup and troubleshooting.
- Mounting and form factor: DIN-rail mounting is common in control panels; verify terminal count and layout to ensure easy wiring and future expansion.
- Protection and reliability: Features like reverse polarity protection, LED status indicators, and robust housing improve long-term reliability in industrial environments.
- Expansion and multi-function options: If you anticipate complex scheduling, consider multi-function relays with multiple timing profiles or programmable calendars.
When selecting a 24V timer relay, balance the required timing capability with the expected load, environmental conditions, and installation constraints. The products above cover a range from compact, short-delay relays to multifunction devices suitable for more intricate automation schemes.
