Relays

The automatic staircase lighting TLA-1 switches on the lighting for the preset time by pressing a button. Even if the keys are blocked, the device switches off after the set time without being damaged. The lighting time can be set from 0.5 minutes to 10 minutes. It is possible to connect buttons with glow lamps.

Switching on lighting fixtures can result in very high inrush currents.

A closing contact bounces 3-7 times until it closes completely. This creates an arc that can melt the contact surface. If the closed contact cools down, micro-welding can occur (contact sticks).

To avoid contact sticking, relays with a leading tungsten contact are used.

With this switch-on peaks of fluorescent lamps with electronic ballasts and LEDs of 800 A / 200 µs or incandescent lamps of 165 A / max. 20 ms can be switched.

The automatic staircase lighting TLA-4 includes 4 different operating modes, which can be set using the rotary switch on the front.

With functions a, b, the operating time can be repeatedly extended by briefly pressing the control button(s). Each short press multiplies the time set by the potentiometer. The maximum value of the activation time thus extended is a maximum of 30 minutes, regardless of the number of presses.

The classic industrial relay with an 11-pin socket is increasingly being replaced by the slimmer, small industrial relay. In addition to the size and the lower price, it has the additional advantage that it has 4 changeover contacts. Even the standard version of the small industrial relays includes a mechanical and an optical (LED) switching status display, as well as a protective circuit (freewheeling diode) for DC coils. The integrated, lockable test button enables a system to be tested very easily during commissioning or when servicing is required. In addition to the standard screw base, there are also those with logical separation and bases with spring-loaded terminals to choose from. All sockets can be equipped with additional circuit modules.

The twilight switch DSE-1 supplied with an light sensor for mounting on the wall.

Via the external control input, the lighting can be suppressed e.g. with a digital timer for a pre-set time.
