EMG
The Phoenix Contact EMG Series encompasses a range of relay modules designed for various industrial applications, offering both electromechanical and solid-state relay options. These modules are engineered for reliable switching of medium to large loads and are suitable for use in control systems, automation, and other electrical circuits.
Key Features:
Compact Design: The EMG Series relay modules are designed with a compact form factor, typically featuring a 17.5 mm width, facilitating efficient DIN rail mounting and space-saving installations.
Versatile Input Voltages: These modules support a range of input voltages, including 24 V DC, 24 V AC/DC, and 230 V AC, accommodating diverse control system requirements.
Robust Output Capabilities: Equipped with various contact configurations, such as single or double changeover contacts, the EMG Series can handle different load types and capacities.
Integrated Protective Circuits: Many modules in this series include built-in protective features like freewheeling diodes, polarity protection diodes, and surge protection, enhancing operational safety and longevity.
Status Indicators: LED indicators are commonly integrated to provide clear visual status of the relay's operational state, simplifying monitoring and troubleshooting.
