Small Multifunctional Time Relay – Wide Voltage, Flexible Timing, Compact Panel Mount

In modern automation, process control, and building management, the ability to precisely control time delays is essential. From staggering motor starts and sequencing conveyors to controlling lighting and HVAC systems, a reliable time relay simplifies complex timing tasks. The Small Multifunctional Time Relay, with its ultra‑compact 40×50 mm panel cutout and weight of only 50g, is engineered to deliver exceptional timing flexibility in a space‑saving package. Featuring a universal AC/DC power supply (DC12‑48V, AC24‑380V 50Hz), a robust 5A output contact, and an impressive array of 28 selectable time ranges (7 delay functions × 4 range multipliers), this relay is the ideal choice for applications ranging from industrial machinery and HVAC control to lighting automation and agricultural timing.

Universal Power Supply for Global Compatibility

One of the relay’s standout features is its extremely wide operating voltage range: DC12V‑48V and AC24V‑380V (50Hz). This makes it compatible with virtually any control system worldwide, from low‑voltage DC logic circuits (e.g., PLC outputs, battery backups, sensors) to standard AC mains (24V, 110V, 220V, 380V). The low power consumption – DC 1.0W / AC 1.0VA – ensures energy efficiency and minimal heat generation, even in sealed enclosures. The wide voltage tolerance also guarantees stable operation in environments with fluctuating supply voltages, a common challenge in industrial settings.

Compact and Lightweight Panel‑Mount Design

Designed for front‑panel installation, the relay requires a 40×50 mm mounting hole, making it one of the smallest time relays in its class. Its shallow depth and low weight (≈50g) allow for high‑density placement on crowded control panels, OEM equipment fronts, or portable test boxes. The clear front layout includes a rotary switch for delay category selection, a DIP switch (positions 1‑4) for time range multiplication, and an adjustment potentiometer, providing intuitive, tool‑free setting of the desired delay period.

Extensive Timing Range – 28 Selectable Time Scales

The relay offers an exceptionally wide and flexible timing capability, combining 7 delay categories (A through G) with 4 range multipliers (switch positions 1‑4). This gives the user 28 different time scales, covering intervals from 0.05 seconds up to 24 hours. The following table summarises the ranges:

Delay Category Switch Pos.1 Switch Pos.2 Switch Pos.3 Switch Pos.4
A 0.05‑0.5s 0.05‑5s 2.5‑30s 0.25‑3m
B 0.1‑1s 0.1‑10s 5‑60s 0.5‑6m
C 0.5‑5s 5‑50s 0.5‑5m 2.5‑30m
D 1‑10s 10‑100s 1‑10m 5‑60m
E 5‑60s 1‑10m 5‑60m 0.5‑6h
F 0.25‑2m 2.5‑20m 0.25‑2h 1‑12h
G 0.5‑4m 5‑40m 0.5‑4h 2‑24h

This comprehensive coverage allows a single relay to replace dozens of dedicated fixed‑range timers. Whether you need a short 0.05‑0.5s pulse for a packaging machine or a long 2‑24h cycle for an irrigation system, this relay provides the right scale with simple switch settings.

Robust Output Contact for Direct Load Switching

The relay features a control output rated at 5A at 220V AC, capable of directly switching a variety of loads, including contactor coils, solenoid valves, small motors, indicator lamps, fans, and resistive heaters. The output contact is designed for reliable operation under typical industrial conditions. With a mechanical life of 10⁷ operations and an electrical life of 10³ operations (at rated load), the relay offers dependable long‑term service.

High Insulation and Dielectric Strength for Safety

Safety is paramount in any control panel. The time relay provides an insulation resistance of ≥100MΩ at DC500V, ensuring excellent isolation between the power supply, timing circuit, and output contact. Its dielectric strength is rated at 1500V AC between coil/electronics and contacts (BCC) and 1000V AC between open contacts (BOC), guaranteeing protection against voltage transients and reducing the risk of arcing or breakdown. These ratings make the relay suitable for use in industrial environments where electrical noise and surges are common.

Environmentally Resilient Design

The relay is built to perform reliably in a wide range of ambient conditions:

· Operating temperature: –10°C to +50°C – suitable for unheated workshops, outdoor enclosures, and temperature‑controlled rooms.
· Humidity: 35% to 85% (non‑condensing) – performs well in most industrial and commercial environments.
These specifications ensure stable timing accuracy and long life even in moderately demanding settings.

Typical Applications

Thanks to its versatile timing ranges and compact size, this time relay is ideal for countless applications:

· Motor Control: Star‑delta starting, sequential starting of multiple motors, and pump alternation.
· HVAC Systems: Compressor anti‑short cycling, fan delay on/off, defrost control, and filter cleaning reminders.
· Lighting Automation: Staircase lighting delay, corridor occupancy control, and signage flashing.
· Industrial Machinery: Conveyor belt sequencing, welding timers, cooling fan delays, and batch process timing.
· Building Automation: Access door hold‑open time, elevator door delay, and ventilation timers.
· Irrigation and Agriculture: Automated watering cycles, fertilizer dosing intervals.
· Laboratory and Test Equipment: Aging test cycles, vibration table timing, and data acquisition interval control.

Easy Installation and Operation

Installation is straightforward: cut a 40×50 mm rectangular hole in the panel, secure the relay with the supplied mounting bracket, and connect the appropriate power supply and load wires. The front‑panel controls are clearly marked, allowing operators to set the desired time quickly without tools. The combination of a rotary category switch and a DIP switch for range multiplication provides a simple, error‑free method for selecting the exact time delay needed.

Conclusion

The Small Multifunctional Time Relay combines an ultra‑compact panel‑mount design, universal AC/DC power supply (up to 380V AC), low power consumption, and a robust 5A output with an exceptional 28‑range timing capability (0.05s to 24h). Its flexibility, reliability, and ease of use make it a perfect choice for engineers, panel builders, and maintenance professionals who need a single timing device to handle a wide variety of applications. Whether you are upgrading an old control panel, designing new equipment, or simply need a reliable delay function, this time relay delivers outstanding value, precision, and performance. Choose it for your next project and experience seamless, repeatable timing control that you can count on.
