In automated production lines, conveyors must start and stop with precision to avoid product jams. The EMG 22-REL/KSR-24/21 relay connects low-voltage PLC outputs to motor starter coils, enabling smooth transitions. Its 6 A switching capacity supports small to medium motor control, while the reinforced insulation ensures operator and equipment safety. The integrated suppression circuit prevents electrical noise from affecting nearby sensors or controllers. Compact design and DIN-rail mounting allow it to fit easily into crowded panels. With reliable switching and long service life, it helps manufacturers maintain consistent throughput while minimizing maintenance interruptions.
Commercial HVAC systems often involve pumps, fans, and dampers that require controlled activation. The EMG 22-REL/KSR-24/21 relay provides safe isolation between the building management system and high-voltage components. Its compact footprint allows multiple relays to be arranged efficiently in one control panel. With robust AgNi contacts, the module can handle frequent switching cycles common in heating and cooling operations. Surge voltage resistance ensures that sensitive automation electronics are protected from electrical disturbances. The yellow LED status indicator offers quick visual confirmation, simplifying monitoring and troubleshooting in large building systems.
Packaging machinery requires safety circuits that immediately disable motion when a guard is opened or an emergency stop is triggered. The EMG 22-REL/KSR-24/21 relay ensures fast response by cutting the control signal to motors and actuators within milliseconds. Its reinforced insulation guarantees reliable separation between control and load sides, crucial for operator safety. The relay’s high mechanical endurance supports millions of cycles, ideal for machines running continuously. Clear LED indication helps technicians verify the relay’s condition quickly, reducing downtime during inspections. This makes it a dependable component in maintaining both safety compliance and production efficiency.
In water treatment applications, pumps are often triggered by level or pressure sensors. The EMG 22-REL/KSR-24/21 relay acts as the interface between the sensor logic and the pump’s control circuit. With a rated switching capacity of 6 A and surge resistance up to 4 kV, it can reliably handle repetitive on/off cycles without risk of control signal disruption. The integrated suppression circuitry protects controllers from interference caused by inductive loads. Its wide operating temperature range allows reliable use in plant environments where conditions fluctuate. By ensuring stable operation, the relay helps operators maintain consistent flow and treatment quality.
