Introduction:
- The ST3PA-B is a power on time delay relay, its delayed time range can be 0-1 seconds, 0-10 seconds, 0-60 seconds and 0-6 minutes.
- A power-on delay relay is a device that starts a device after a certain time delay. For example, if you set the delay time for this ST3PA-B to 60 seconds, once you turn on the power, the load will not start working immediately, but will start after 60 seconds.
- As mentioned above, there are 4 delay times available, how to adjust? There is a dip switch, if you turn it to 24, its range is 0-1 second, 14 is 0-10 seconds, for more details, please check the table below:
- The SP3PA-B time relay installation method is DIN rail mounting with a base socket, product dimension is 41*55*83mm, if you want a space-saving one, please have a look at our multifunctional time delay relay.
- Another alternative to this product is the H3CR-A8, which has more functions than this simple time delay relay, including time delay relay, cycle on/off, interval, etc.
- Applications of the ST3PA-B include equipment startup sequence control, stage lighting and sound sequence control, and other scenarios.
