Relays/Switches

VR 3tr-U
200/205 VR 3tr-U

Contact protection relays are used for amplifying of switching signals. They are usually in use in industrial sectors.



Our contact protection relays are used e.g. with following applications:

- Contact-thermometer

- Contact dial thermometer

- Contact-gauge

- Contact-hygrometer



The supply of signal voltage is galvanically isolated and conducted touch-proof.



The contact protection relays Type VR are populated with change-over contact and are designed for working in opened and closed current either, or e.g. for heating and cooling.


TST tr
220 TST tr

This kind of relay is serially manufactured as floor-mounted relay, but can be delivered with stage clamp. The units are inside a small plastic housing of grey Makrolon.

Power switch, control lamp for operation, 3-pole diode plug for contact giver and protective contact socket for the controlled load are clearly arranged on the front. At the side there is a feeder with a protective contact plug.


TST tr-ET
220 TST tr-ET

This kind of relay is serially manufactured as floor-mounted relay for electronical thermometers, but can be delivered with stage clamp. The units are inside a small plastic housing of grey Makrolon.

Power switch, control lamp for operation, 3-pole diode plug for contact giver and protective contact socket for the controlled load are clearly arranged on the front. At the side there is a feeder with a protective contact plug.


TST tr-A
220 TST tr-A

This kind of relay is serially manufactured as floor-mounted relay, but can be delivered with stage clamp. The units are inside a small plastic housing of grey Makrolon.

Power switch, control lamp for operation, 3-pole diode plug for contact giver and protective contact socket for the controlled load are clearly arranged on the front. At the side there is a feeder with a protective contact plug.

In opposite to the TST tr the TST tr-A has an advanced security control.


LR 5
230 LR 5

AC power controller are used to set the capacity of AC power loads, as like as stirrer motors, radiators etc. The units are inside a small plastic housing of grey Makrolon. All elements are clearly arranged on the front. At the side there is a feeder with a protective contact plug.

Thyristor power switches are used for the contact-free switching of a.c. loads. A typical application is the switching of resistive-inductive loads at high switching rates, especially in the industrial sector, such as in the plastics packaging industry, in HVAC engineering and in the construction of industrial furnaces.The control and power sections are electrically isolated by optocouplers.The control signal range is compatible with the logic outputs of our controllers.The power section operates...
