Omron offers a wide range of relay timers, which are used in industrial control systems to delay or time specific actions. These timers allow for precise control over the timing of operations in various processes, machinery, and automation systems. Depending on the specific model, Omron relay timers come in different configurations, such as digital or mechanical, and offer a variety of timing functions.
Common Features of Omron Relay Timers:
-
Types of Timing Functions:
- On-delay Timer: The relay closes its contacts after a set time delay once the input signal is received.
- Off-delay Timer: The relay keeps its contacts closed for a set period after the input signal is removed.
- Interval Timer: The relay operates for a set period after the input signal is received, then returns to its original state.
- Cyclic Timer: The timer continuously operates at regular intervals for certain processes.
-
Voltage Ratings:
- Omron relay timers typically come in various coil voltages, such as 12V, 24V, 110V, 220V AC/DC, to suit different control panel requirements.
-
Contact Configuration:
- Many Omron timers feature NO (Normally Open) and NC (Normally Closed) contacts, offering flexibility for different switching needs.
- These timers may be used to control motors, heaters, lighting, or other systems that require time delays for operation.
-
Digital vs. Analog:
- Digital Timers: Often more precise and offer easy configuration through a digital interface, such as a display screen and knobs or buttons.
- Analog Timers: Feature mechanical dials for setting the time delay and are often simpler but still reliable.
-
Time Range:
- Omron timers offer a wide time range, often from milliseconds up to hours, depending on the model and application needs.
