Bistable memory relay / Start-stop relay, pulse on pulse / Latching relay

TENSE Bi-stable electronic impulse relay (start-stop/memory relay), 150-260 V AC

The bi-stable electronic impulse relay from TENSE (Turkey) allows you to control lighting or other devices from any number of locations using push buttons connected in parallel. It is ideal for domestic installations, commercial buildings, and industrial systems where simple impulse control is required without the need for conventional stair or cross switches.

Description and features

The relay allows you to switch the device on or off based on a short pulse from a momentary push button (bell). An internal bi-stable mechanism ensures that the relay changes its state after the button is pressed and remains in that state until the next impulse. This ensures simple and reliable control using one or more controllers in parallel.

A great advantage of this model is the increased safety: there is no need to supply 220/230 V mains voltage to the push button input. A simple short circuit of the push button contacts is sufficient, which does not endanger the user and does not require the use of live wires at the control point.

Advantages and features

Safe operation without high voltages at the push buttons
The control inputs operate solely on the closed-circuit principle, eliminating the risk of electric shock.

Control from any number of locations
Connecting any number of push buttons in parallel allows for replacing cross and toggle switch systems and greatly simplifying wiring.

Saves wiring
Connecting two wires from the push buttons in parallel eliminates the need for complex switch combinations.

Compact size - 1 module
The relay does not take up much space and is easy to install in any domestic or industrial control panel.

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