Cost-effective, easy-to-use safety controller for smaller machines replaces the functionality of two or more safety relay modules and features an intuitive user interface and advanced diagnostic capabilities.Two safety six amp relay outputs each with three N.O. sets of contacts. Ten inputs, including four that can be used as non-safe outputs. Automatic Terminal Optimization (ATO) can increase inputs from 10 up to 14. In-Series Diagnostics (ISD) provides detailed status and performance data from each connected safety device which can be accessed with an HMI or similar device.
