G9SX-LM

Safety controllers

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
