The Applications of Phoenix Contact EMG 22-REL/KSR-230/21

1. Precision in Packaging Machinery

Modern packaging machines rely on accurate timing to cut, seal, or fill products. The EMG 22-REL/KSR-230/21 relay module ensures reliable switching when sensors detect items moving at high speeds. Its rapid response time and reinforced insulation protect sensitive controllers while driving actuators and motors safely at 230 V. This prevents misalignment or product waste caused by delayed activation. With compact housing, multiple relays can fit into one panel, supporting synchronized operations. Maintenance crews also benefit from the built-in LED indicator, which shows real-time switching status, reducing troubleshooting time during production runs and keeping packaging throughput consistently high.

2. Climate and Ventilation Control

Heating, ventilation, and air-conditioning systems in commercial facilities often require safe switching of fans, compressors, or heating coils. The EMG 22-REL/KSR-230/21 provides a secure interface between control electronics and high-voltage devices, preventing faults from reaching delicate thermostats or controllers. Its 6 kV reinforced insulation guarantees safety against electrical surges while operating in varying temperatures. Thanks to the module’s slim 22.5 mm width, engineers can mount several relays within a single cabinet to control multiple HVAC functions. This compact design allows energy-efficient climate management, with reliable switching that ensures comfort levels remain stable across office buildings, hospitals, and industrial sites.

3. Conveyor and Material Handling Systems

Conveyors require frequent motor start and stop commands that must handle both continuous loads and short bursts of inrush current. The EMG 22-REL/KSR-230/21 relay module is engineered to manage up to 6 A of current, making it a reliable solution for controlling belt drives, sorters, and automated pick-and-place machines. Its fast switching minimizes system lag, while built-in suppression circuitry reduces electrical noise that can disrupt sensors. The yellow LED indicator allows maintenance teams to confirm switching states quickly, lowering downtime during inspections. Compact size and DIN rail mounting simplify integration, enabling efficient control of multiple conveyor lines in busy factories.

4. Renewable Energy Management

In renewable energy installations, such as solar or small wind systems, switching between sources, storage units, or backup supplies is crucial. The EMG 22-REL/KSR-230/21 provides the necessary safety margin with reinforced isolation, preventing unwanted voltage spikes from damaging sensitive equipment. Its wide operating voltage range ensures stable performance even with fluctuating input conditions common in renewable setups. By occupying minimal panel space, the relay supports compact inverter and control cabinets. The long mechanical service life extends system reliability, while the LED status display helps technicians monitor switching events at a glance, ensuring continuous, efficient distribution of renewable energy resources.
