TENSE Bistable electronic pulse relay (start-stop/memory relay), 150-260 V AC

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

Description and features

With the relay, the device can be switched on or off based on a short pulse from a momentary (bell) button. An internal bistable mechanism ensures that the relay changes state after the button is pressed and remains in that state until the next pulse. This provides simple and reliable control by one or more controllers in parallel.

A major advantage of this model is the increased safety - it is not necessary to supply 220/230 V mains voltage to the push button input. A simple short circuit of the button contacts is sufficient, which does not endanger the user and requires no power wires at the control point.

Advantages and features

Safe operation without high voltages on the buttons
The control inputs operate only according to the closed circuit principle, eliminating the risk of electric shocks.

Operation from any number of locations
By connecting any number of buttons in parallel, you can replace cross and switch systems and greatly simplify the wiring.

Saves wiring
Thanks to the two-wire parallel connection of buttons, no complex switch combinations are needed anymore.

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

DIN rail mounting 35 mm
Enables standardized quick mounting in switchboards.
