In industrial conveyor systems, safety is critical to protect operators and equipment. This relay module can be configured as part of a safety interlock, shutting down motors when an emergency stop or protective guard is triggered. Its safe isolation between coil and contacts ensures the control system is fully protected from high-voltage circuits. The fast 7 ms switching time enables immediate reaction, while dual changeover contacts provide redundancy for higher reliability. With a long mechanical service life, it continues operating dependably even in round-the-clock production environments, minimizing downtime and enhancing worker safety.
Large-scale heating, ventilation, and air conditioning systems rely on reliable relay modules to coordinate fans, compressors, and dampers. The EMG 17-REL module acts as an effective interface between low-voltage building automation controllers and high-power electrical equipment. Its gold-plated contacts guarantee reliable signal transmission despite frequent switching, while the compact 17.5 mm DIN-rail design saves space in crowded control panels. Reinforced insulation protects sensitive electronics from power surges and interference, ensuring stability. The wide operating temperature range supports performance in mechanical rooms where conditions can fluctuate, making it ideal for modern energy-efficient building control systems.
Water distribution and wastewater facilities often require remote-controlled pump operations with precise timing. This relay module serves as the switching link between control logic and heavy pump motor contactors. With a switching capacity up to 1250 VA, it handles motor loads without compromising reliability. Built-in interference suppression prevents false activations caused by long cable runs or electrical noise, which are common in outdoor or remote installations. Its screw terminals simplify on-site wiring, while the durable design supports years of dependable use, reducing service calls. By providing reliable switching under demanding field conditions, it helps maintain consistent water supply operations.
Packaging equipment demands precise, repeatable switching to synchronize conveyors, actuators, and sealing units.
