Citphto DC 5V Timer Delay Relay Module Review

Introduction

Precise timing control is a fundamental requirement in modern electronics, automation systems, and smart home solutions. From turning devices on or off after a delay to creating repeating cycles for motors, lights, or alarms, a reliable timer relay module can significantly simplify complex control logic. Compact, versatile, and highly configurable timing modules are especially valuable for developers, hobbyists, and professionals working with low-voltage control systems.

This Citphto DC 5V Timer Delay Relay Module review delivers a comprehensive, original, and easy-to-understand analysis of a multifunction timing controller widely available on Amazon. Designed with a digital LED display, infinite cycle capability, and adjustable timing range from 0.1 seconds to 99 hours, this module offers impressive flexibility for a wide range of applications.

Product Overview

The Citphto DC 5V Timer Delay Relay Timing Controller Module is a compact electronic control unit that integrates multiple timing and triggering functions into a single board. It is designed to operate on DC 5V input power and can safely control both DC and AC loads through its onboard relay.

Unlike basic timer relays that perform only one function, this module supports four distinct working modes:

• Delay mode
• Timing mode
• Cycle mode
• Trigger mode

The adjustable time range of 0.1 seconds to 99 hours allows the module to be used in both fast-response circuits and long-duration automation tasks. A digital LED display provides clear, real-time feedback for time settings and operating status.

What’s Included in the Package

All essential components are pre-mounted on the board, allowing immediate integration into projects without additional hardware.

Core Technical Specifications

Design and Build Quality

Compact and Functional Layout

The Citphto timer delay relay module features a compact printed circuit board layout that is easy to integrate into enclosures, control panels, or development boards. All components are clearly labeled, making setup and adjustment straightforward even for users with limited electronics experience.

The onboard digital LED display is bright and legible, ensuring time values and mode indicators remain visible in various lighting conditions.

Durable Relay and Components

The relay is rated for high switching durability, with a service life of up to 100,000 operations. This makes the module suitable for repetitive tasks such as cycling motors, lighting systems, or alarms over extended periods.

High-quality electronic components and solid solder joints contribute to stable performance across a wide temperature range.

Power Requirements and Electrical Performance

5V Input Operation

The module operates exclusively on DC 5V, making it compatible with:

• USB power supplies
• Microcontroller boards
• Regulated 5V power adapters

Low power consumption ensures efficient operation, even in always-on systems.

This low current draw makes the module ideal for battery-powered or energy-efficient systems.

Relay Output Capability

Despite its compact size, the module can control relatively high-power loads through its onboard relay.

This allows the module to control a wide variety of devices, including motors, lighting systems, pumps, and other electrical equipment, provided proper safety practices are followed.

Timing Functions Explained

One of the strongest features highlighted in this Citphto DC 5V timer delay relay module review is its multi-function timing capability.

1. Delay Mode

In delay mode, the relay activates or deactivates after a preset delay once power or a trigger signal is applied. This is useful for:

• Power-on delay protection
• Sequential device startup
• Alarm delay systems

2. Timing Mode

Timing mode allows the relay to remain active for a specified duration before switching off automatically. Common uses include:

• Timed lighting
• Motor runtime control
• Equipment shutdown timers

3. Cycle Mode

Cycle mode enables continuous ON/OFF cycling with adjustable on-time and off-time durations. This mode is widely used in:

• Ventilation systems
• Intermittent pumps
• Flashing indicators

The infinite cycle function allows the process to repeat indefinitely until manually stopped.

4. Trigger Mode

Trigger mode allows the relay to respond instantly to an external signal, making it suitable for:

• Sensor-based automation
• Smart home triggers
• Security system integration

Adjustable Time Range

The module supports an exceptionally wide timing range:

This flexibility makes it suitable for both rapid-response control and long-term automation tasks without requiring hardware changes.

User Interface and Operation

Digital LED Display

The digital display provides clear feedback on:

• Selected timing values
• Operating mode
• Active relay status

This eliminates guesswork and reduces configuration errors.

Control Buttons

Built-in buttons allow users to:

• Switch between modes
• Increase or decrease time values
• Start or stop operation

The interface is intuitive, though users are advised to review the product description carefully before initial setup to fully understand mode selection and parameter adjustment.

Temperature Resistance and Environmental Performance

The module is designed to operate reliably across a wide temperature range:

This makes it suitable for use in environments such as:

• Industrial control panels
• Automotive systems
• Outdoor enclosures (with proper protection)

Applications and Use Cases

The Citphto DC 5V timer delay relay module is widely used in both professional and hobbyist environments.

Common Applications

• Smart home automation
• Anti-theft alarm delay systems
• Robotics and motion control
• PLC development and testing
• Automation equipment
• Electronic product development
• Timed power control
• Lighting and fan automation

Its flexibility allows it to replace multiple single-function modules, reducing system complexity.

Smart Home Integration

In smart home environments, timing control plays a key role in automation. This module can be used to:

• Delay alarm activation after arming
• Control lights with timed schedules
• Automate appliances without constant supervision

The trigger mode makes it particularly effective when paired with sensors or control boards.

Reliability and Longevity

The relay’s rated lifespan of 100,000 cycles ensures long-term reliability in applications involving frequent switching. Combined with stable electronic components and low power consumption, the module is well-suited for continuous operation.

Proper installation, adequate ventilation, and operation within rated limits further enhance longevity.

Advantages and Limitations

Advantages

• Wide timing range from 0.1s to 99h
• Four functional modes in one module
• Clear digital LED display
• Low power consumption
• High relay switching capacity
• Wide operating temperature range
• Long relay service life

Limitations

• Operates only on DC 5V input
• Requires understanding of timing modes for full functionality
• Not weatherproof without enclosure

These limitations are typical for compact electronic timing modules and do not detract from overall performance.
