PMH-10M-DC24V

Time Delay Relays are metering devices that offer a wide range of features and applications. They are used primarily for time delay applications such as window control, safety interlock reset, and timed protection operations. The PMH-10M-DC24V is one such device, offering versatility and convenience for a variety of time delay applications.

Features

• 24V DC operating voltage
• Powered from 12V or 24V power supplies
• Internal energizing coil
• Adjustable timing range from 0.2 sec to 300 sec
• Trigger input
• N.O./N.C. output
• Durable and reliable

Applications

The PMH-10M-DC24V is ideal for applications that require a reliable timer and flexible response time. Examples include:

• Automatic lighting control
• Delayed closing or resetting of safety interlocks
• HVAC system monitoring
• Time marking for processes and equipment
• Delayed start of pumps and motors
• Group delays for multiple connected motors/devices

Working Principle

When energized by a 24V power supply, the PMH-10M-DC24V activates an internal energizing coil which sets the time delay mechanism. This is controlled by a trigger input which is activated either externally or internally.Once the trigger input is activated, the PMH-10M-DC24V will count down according to its pre-set time delay. During this countdown, the N.O./N.C. output can be controlled either by external signals or internally, allowing for flexibility in controlling the time delay process. When the time delay runs out, the PMH-10M-DC24V will switch its N.O./N.C. contact state to indicate the time delay has ended. The device will then reset itself and be ready for the next triggering event.

Conclusion

The PMH-10M-DC24V is an efficient and reliable time delay relay with multiple applications. It offers adjustable timing from 0.2 sec to 300 sec, making it a convenient and effective solution for a wide range of applications. It is a cost-effective solution for any timing or output control needs.
