Control relay

Start by identifying the load type, voltage, and control needs. In this range you’ll find two‑pole devices rated up to 63A for medium‑power applications, plus voltage‑monitoring relays and other switching options. Check the operating voltage (Ue) to match your system, for example 440VAC in common power networks, and review insulation and surge ratings (Ui and Uimp) for safety against spikes. Also decide on mounting style—whether you want a panel‑mounted DIN unit or a PCB‑mounted relay—and whether your job requires direct motor control or simple signal switching.

Ui is the maximum insulation voltage the device can safely separate between circuits; Ue is the voltage it can operate at during normal use; Uimp is the impulse withstand voltage that protects against lightning and switching surges. A device with Ui 500VAC, Ue 440VAC, and Uimp around 4kV can safely handle typical industrial networks and transient spikes without breakdown, ensuring reliable protection and longevity in a control panel.

Motor panels benefit from relays designed for higher current and rugged switching, such as motor‑contactor style devices, while simple logic circuits can use voltage relays or solid‑state types for quiet switching and fast responses. The range includes both: you’ll find devices suitable for medium to high current motor control as well as options tailored for signaling and automation tasks, letting you match the load and control logic precisely.

Yes, you can integrate a voltage relay with a digital time relay to add timing and safety checks in a single control loop. This lineup includes a digital time relay that provides ON/OFF delay with a clear interface, enabling precise sequencing when combined with sensing relays. Ensure the input and output voltages align, and keep protection devices sized to the same supply range so the cascade operates smoothly without false trips.

Safety hinges on choosing devices with appropriate voltage ratings and insulation, plus adherence to recognized standards for electrical controls. Look for Ui and Ue values that fit your network and confirm standards applicable to industrial relays, such as IEC guidelines, to ensure reliable operation in demanding environments and reduce the risk of insulation failure during faults or surges.

Choose based on your panel design and space: DIN‑mount relays fit standard DIN rails on control panels, while PC‑board variants are designed for direct integration onto printed circuit boards. This range provides both mounting styles to suit different installation needs, letting you select devices that align with your electrical panel layout and wiring scheme for neat, reliable connections.
