Limited speed monitoring unit
Safe Limited Speed monitoring unit for complete support of maintenance mode in machinery.
• Preset of limited speed frequency by using integrated preset switches
• Easy integration in G9SX-Systems by using unique logical "AND" connection
• Clear LED diagnosis of all inand output signals for easy maintenance
• Applicable up to Safety Category 3 according to EN954-1 using Omron proximity sensors
