Impact20 Modules

Impact20 is an economic fieldbus I/O station from Murrelektronik. Thanks to the small amount of space required, Impact20 is perfectly suitable for applications in terminal boxes and in control panels. A special advantage is the low height of Impact20.

Impact20 connects actuators and sensors in a very cost-effective manner. This fieldbus I/O station is strictly oriented to the requirements of modern machine installations. This means that Impact20 features predefined inputs and outputs, port-related shutdown in case of fail-ure and group diagnostic via the bus. Pluggable spring clamp terminals have integrated sta-tus LEDs for single channel diagnostics. All of these and more make Impact20 the right choice for many applications.

Impact20 is also available for various other fieldbus protocols.
