If special loads such as inductivities or high inrush currents are to be switched or monitored safely and reliably, you need individually tailored relay modules and solid-state relays. These customized solutions extend the service life of the switching element and, what’s more, they can be installed in the panel in a space-saving manner thanks to optimized connection options.
Optimal relay selection for maximum plant availability
Our support ensures you receive optimally dimensioned relay products for your application quickly. This way you can reliably avoid unnecessary machine and system damage and reduce downtimes to a minimum.
MICROOPTO ACTOR power solid-state relays
High availability, long lifetime and permanent reliability are essential factors in relay selection. MICROOPTO ACTOR power solid-state relays are extremely robust and withstand short and high inrush current peaks below 10 ms. Because they are designed without mechanical components, their outputs cannot weld. This makes them ideal for use, for example, in switching LED lamps or devices with wide-range inputs. Their high reliability is further enhanced by an integrated suppressor circuit for inputs and outputs.

TERMSERIES for capacitive loads
Hidden capacitive load shares exist in more and more applications. They increase the risk of welded relay contacts. TERMSERIES electromechanical relays have particularly durable contact materials and can easily withstand inrush currents of up to 800 A for 200 μs. In addition to the robust AgSnO contacts, we have equipped some of the products with a particularly weld-resistant tungsten contact. It closes in advance of the AgSnO contact and passes on the inrush current. Afterwards, the AgSnO contact closes to bridge the tungsten contact. This compensates the power loss that would occur if the less conductive tungsten contact were used.

D-SERIES DRL miniature power relays
Powerful relay modules are required for switching inductive loads. The miniature power relays of the D-SERIES DRL are particularly compact and have up to 4 changeover contacts. Thanks to their durability they are a permanently reliable solution for the switching of inductive AC loads up to 5.5 A when using the 1 CO contact variants.
D-SERIES DRW power relays
Even more powerful than our DRL relays are the industrial miniature relays D-SERIES DRW. They are particularly reliable and robust. This is achieved by using wear-resistant contact materials and an enlarged contact opening that allows the arc to break off more quickly during switching. DRW power relays are ideally suited as a permanently reliable solution for switching inductive AC loads up to 5.5 A (with 2 CO contacts) or up to 5 A (with 3 CO contacts).
MICROOPTO power solid-state relays
MICROOPTO solid-state relays in terminal block format offer a lot of power in a width of only 6.1 mm. They can be used as reliable switching amplifiers for actuators up to 300 V DC and 10 A, which also include solenoid valves and contactors. Thanks to their protective circuitry in the output, MICROOPTO solid-state relays are capable of reducing even large voltage peaks, such as those occur when switching inductive loads.

D-SERIES DRH power relays with blow-out magnet
Industrial applications often have high requirements. D-SERIES DRH relays are designed for reliable switching of high inductive DC loads and provide higher wear resistance and longer life in demanding applications. This is achieved by an integrated blow-out magnet as well as an optional contact series connection. The blow-out magnet ensures that the arc generated during switch-off is quickly extinguished. Combined with the clever contact series connection and the larger contact opening, contact wear is significantly reduced. This means that inductive loads and high DC currents up to 220 V DC/10 A can be switched reliably.
MICROOPTO power solid-state relays for high DC voltages
In the industrial segment, large voltage peaks can lead to rapid contact wear. The compact and powerful MICROOPTO power solid-state relays in terminal block format serve as reliable switching amplifiers for loads up to 300 V DC and 1 A – e.g. solenoid valves and contactors. Despite their small width of only 6.1 mm, they can also reduce larger voltage peaks, such as those that occur when switching off inductive loads, thanks to a protective circuit in the output.

TERMSERIES actuator variants
The lower the wiring effort, the higher the cost-effectiveness. With TERMSERIES actuator variants, supply and return wire for the load can be connected directly to the relay module. This eliminates the need for additional terminal blocks and significantly reduces wiring time. In addition, TERMSERIES interface adapters and cross-connectors ensure efficient wiring by eliminating the need for time-consuming and costly single-wire wiring.
TERMSERIES interface adapter
To reduce wiring times, pre-assembled cables are used between the control system and the interface level and are simply connected to the TERMSERIES adapter. This enables throughput times in switch cabinet building to be significantly reduced. The adapter has a universal fit and offers a genuine space advantage in interaction with the TERMSERIES products with identical contours.
