What is a Delay On Operate Time Relay?
A Delay On Operate (DOO) time relay is a relay that will wait for a set period of time after the application of power before turning its output on. It is most often utilized in systems where parts need to turn on in succession or where there are delays necessary to avoid overlap or load spikes.
The Electromatic SA 245 has been built to provide this capability with maximum accuracy and user-friendly operation.
Features of Electromatic SA 245 230V Time Relay
The following are some of the key features of this model:
Adaptable Time Range: The relay can provide a delay from 3 to 60 minutes, hence usable for short-term as well as long-term operations.
Voltage Suitability: Compliant with 230V AC, a voltage commonly used in most industrial applications.
Compact Design: Simple to mount in control panels and space-restricted areas.
Durable Build Quality: Constructed for strength and long-term operation in challenging industrial environments.
DIN Rail Mounting: Makes installation easier and integration with current systems simpler.
LED Indicators: Gives visual indication of power and relay status, helping facilitate rapid diagnostics.

Where and Why to Use It?
The Electromatic SA 245 relay is applicable in numerous applications, such as:
1. Industrial Automation
In manufacturing plants, timing relays such as the SA 245 assist in sequence control. For example, if a conveyor must wait 10 minutes before operating after another machine comes on, this relay can be programmed accordingly.
2. Lighting and HVAC Systems
Applicable in environments where lights, fans, or heating systems must come on after a predetermined time delay, minimizing load spikes and enhancing system reliability.
3. Pumping Systems
To ensure prevention of motor overload or sequential switching of pumps, the time delay will allow each of them to start one by one.
4. Safety and Control Panels
Delay relays assist in handling shutdown/start-up routines, thereby providing proper sequence of operations to avert accidents or damages to equipment.
