Bistable memory relay / Start-Stop relay, pulse pulse / pulse switch

TENSE Bistable electronic pulse relay (Start-Stop / memory relay), 150-260 V AC

TENSE (Turkey) bistable electronic pulse relay allows control of lighting or other devices from any number of locations using parallel-connected push buttons. It is ideal for households, commercial buildings, and industrial systems where simple pulse control is needed without conventional staircase or cross switches.

Description and features

The relay allows turning the device on or off based on a momentary (bell button) short pulse. The internal bistable mechanism ensures the relay changes state after the button press and remains in that state until the next pulse. This provides simple and reliable control by one or multiple controllers in parallel.

A major advantage of this model is greater safety - there is no need to apply 220/230 V mains voltage to the button input. Simply shorting the button contacts is enough, which does not endanger the user or require live wires at the control point.

Advantages and features

Safe operation without high voltage at the buttons
Control inputs operate only on the closed circuit principle, eliminating the risk of electric shock.

Control from any number of locations
Parallel connection of any number of buttons allows replacing cross and switch systems and significantly simplifies wiring.

Saves wiring
Two-wire parallel connection of buttons eliminates the need for complex switching combinations.

Compact size - 1 module
The relay takes up little space and is easy to install on any home or industrial control panel.

35 mm DIN rail mounting
Allows standardized quick installation in distribution boards.
