ST3P Mechanical Timer with 4 Adjustable Ranges for Automatic Control
This time relay simplifies the automation of electrical equipment through precise mechanical programming, without complex digital systems. With four selectable timing intervals, you can control lighting, fans, or pumps exactly when you need them. Ideal for industrial, agricultural, or residential applications where mechanical reliability matters more than advanced features.
What you get with this product
- Reliable automation without digital programming — set the interval directly on the rotary knob, it works immediately
- Four flexible timing ranges — choose between 4 minutes, 24 minutes, 4 hours, or 24 hours according to your needs
- Simple DIN rail mounting with included socket — integrates into existing electrical panel without modifications
- Robust mechanism without fragile electronic components — resistant to voltage fluctuations and electromagnetic interference
- 3A power contact for direct equipment control — start small motors, fans, or lights without additional relays
- Automatic reset after each cycle — no manual intervention required for each use
How it works and how to install it
The relay is mounted on a 35mm DIN rail using the MF 6950 socket provided in the package. You wire the 220V AC power supply and the load according to the diagram drawn on the housing, then select the desired timing range by positioning the internal jumpers according to the instructions. Turn the central knob to set the desired time, and the mechanism starts the countdown automatically when power is connected or the ON button is pressed.
After the set time expires, the relay contact switches automatically, interrupting or starting the connected circuit. Installation requires basic electrical knowledge and adherence to safety standards for 220V equipment.
Frequently asked questions
Can I use this relay to control a water pump?
Yes, if the pump consumes a maximum of 3A at 220V. For higher power, connect the relay to an intermediate contactor.
How do I switch between the 4-minute and 24-hour ranges?
By repositioning the internal jumpers according to the diagram on the housing — no special tools required, just opening the cover.
Does it reset itself after each cycle or does it need to be restarted manually?
It operates cyclically — after expiration, you can manually reset the knob for a new cycle or configure automatic reset through the wiring mode.
