Small Panel-Mount Time Relay – Versatile Timing Control for Industrial and Commercial Applications

In the world of automation, process control, and building management, the ability to introduce precise time delays is often a fundamental requirement. Whether sequencing machinery, controlling lighting, or protecting equipment, a reliable time relay is an indispensable tool. The Small Panel-Mount Time Relay, with its compact 45×45mm installation cutout, is engineered to deliver accurate and flexible timing control in a space‑saving package. Offering a wide range of timing scales (from 0.05 seconds up to 60 hours), universal AC/DC power supply compatibility, and a robust 5A output contact, this relay is the ideal solution for applications ranging from motor starting and HVAC control to lighting automation and industrial sequencing.

Compact Design for Easy Panel Integration

The relay is designed for panel mounting with a standard 45×45mm installation hole size, making it a perfect fit for most industrial control panels, distribution boxes, and OEM equipment front panels. Its compact form factor allows for high‑density layout without sacrificing usability. The front panel features an intuitive time‑scale selector, a time unit indication window (0.1s, sec, min, hrs), and an adjustment dial, providing straightforward setting of the desired delay period. Weighing approximately 160g, the relay is lightweight yet robust enough for long‑term service.

Wide Timing Range and Flexible Scale Selection

A standout feature of this time relay is its extensive and user‑configurable timing range, covering four distinct time units and four scales per unit. The time unit is selected via a clear indication window, while a rotary switch chooses the scale. The available combinations are:

· 0.1s unit (range 0.05‑6s, 0.1‑1.2s, 0.25‑3s, 0.5‑6s) – ideal for short delays in fast‑cycling processes, such as packaging machinery or electronic testing.
· sec unit (range 0.05‑6s, 1‑12s, 2.5‑30s, 5‑60s) – suitable for general‑purpose delays like conveyor belt sequencing or pump start‑up staggering.
· min unit (range 0.5‑6min, 1‑12min, 2.5‑30min, 5‑60min) – perfect for longer intervals, such as compressor idle periods or ventilation fan cycling.
· hrs unit (range 0.5‑6h, 1‑12h, 2.5‑30h, 5‑60h) – designed for extended‑duration applications, including irrigation scheduling, lighting control, and equipment maintenance reminders.

This multi‑scale, multi‑range capability allows a single relay model to replace dozens of fixed‑time devices, significantly reducing inventory and simplifying design.

Universal Power Supply for Global Compatibility

The time relay accepts a wide input voltage range: DC12V‑48V and AC24V‑220V (50Hz). This universal power supply makes it compatible with virtually any control system worldwide, from low‑voltage DC logic circuits (e.g., PLC outputs, battery backups) to standard AC mains (e.g., 110V, 220V). The low power consumption (DC 1.0W / AC 1.0VA) ensures energy efficiency and minimal heat dissipation, even in sealed enclosures. The wide voltage tolerance also provides reliable operation in environments with voltage fluctuations.

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, 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 long‑term dependability.

High Insulation and Dielectric Strength for Safe Operation

Safety is a key consideration 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.

Environmentally Resilient Design

The relay is built to operate 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 timer, cooling fan delay, and batch process timing.
· Building Automation: Access door hold‑open time, elevator door delay, and ventilation timer.
· Irrigation and Agriculture: Automated watering cycles (hours range), 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 45×45mm square hole in the panel, secure the relay with the included 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 time unit indication window prevents confusion between seconds, minutes, and hours, reducing setup errors.

Conclusion

The Small Panel-Mount Time Relay combines compact dimensions, a wide timing range (0.05s to 60h), universal AC/DC power compatibility, and a robust 5A output into a single, easy‑to‑use device. Its flexible time scales and multiple ranges make it a true multi‑tool for timing applications, eliminating the need for several dedicated timers. Whether you are upgrading an old control panel, designing new equipment, or simply need a reliable delay function, this time relay offers exceptional value, simplicity, and performance. Choose it for your next project and experience precise, repeatable timing control that you can count on.
