Models available with In-Series Diagnostics (ISD), which provides detailed status and performance data from each connected button that can be accessed with an HMI or similar device. Patented E-stop base will flash red when actuated and indicate armed status with either green, yellow, or no illumination. Latching design complies with ISO 13850 per IEC 60947-5-1. Safe Break Action ensures NC contacts will open if the contact block is separated from the actuator.
