Chauvin Arnoux - Model RMD -High-Performance Relays for Industrial Applications
The RMD relays are designed for high-performance industrial applications, featuring options with 4, 8, or 16 changeover contacts. They maintain a robust mechanical design, similar to the RGM series, ensuring consistent specifications and performance. Notable features include coil continuity supervision via a built-in auxiliary relay and functionalities for continuous checks and periodic testing. The knurled contacts provide multiple electrical connection points, resulting in reduced ohmic resistance, which enhances the electrical life expectancy of the component. These relays are optimized for managing strongly inductive DC loads and very low interface signal loads. With an exceptional breaking capacity, the RMD relays handle heavy-duty DC loads even under frequent switching scenarios. The optional magnetic arc blow-out further increases the breaking capacity. They accommodate nominal voltage ranges from 12 to 220VDC/440VAC, and their adaptability makes them suitable for demanding sectors like electricity generating and transformer stations, railways, and industries with continuous production processes.
Very high performance relays available with 4, 8 or 16 changeover contacts. These relays share the same basic mechanical design with the RGM series, and offer the same specifications and performance.
Coil continuity supervision and monitoring by means of a built-in auxiliary relay. Continuous check and periodic test functions available.
Knurled contacts to provide lower ohmic resistance thanks to the multiple electrical connection points:
- Extended electrical life expectancy of the component
- Optimal performance for strongly inductive DC loads and for very low loads, such as in the case of interface signals
Exceptional breaking capacity for controlling very heavy duty DC loads, also with intensive switching frequency.
Optional magnetic arc blow-out for even higher breaking capacity.
Available nominal voltage from 12 to 220VDC/440VAC.
