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

The bistable electronic impulse relay from TENSE (Turkey) allows control of lighting or other devices from any number of locations using parallel-connected push buttons. It is ideal for home installations, commercial buildings, and industrial facilities where simple pulse control is required without using conventional staircase or crossbar switches.

Description and features

The relay allows switching the device on and off based on a short pulse from a push button (doorbell button). An internal bistable mechanism ensures that the relay changes its state after pressing the button and remains in that state until the next pulse. This ensures simple and reliable control by one or more parallel-connected control devices.

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

Advantages and features

Safe operation without high voltages at the push buttons
The control inputs operate only on the principle of no current flow, so the risk of electric shock is excluded.

Control from any number of locations
By paralleling any number of push buttons, you can replace cross and switch systems and greatly simplify wiring.

Saves wiring
The two-wire parallel connection of push buttons eliminates the need for complex switch combinations.

Compact size - 1 module
The relay takes up little space and can be easily installed in any private or industrial control panel.

Mounting on 35 mm DIN rail
Enables standardized quick mounting in control panels.
