Overview Four separate optical sensing channels monitor one or multiple Fiber Optic Switches, Point, Grids or Optical E-Stop Buttons in the same fiber optic loop. Flexible and easy to install, the controller is a low-cost alternative to cumbersome and costly methods required for machine safeguarding. Each of the four channels controls multiple inputs, to protect personnel from hazardous equipment and to protect critical tooling or materials in process. Controller signals the machine control circuit to stop when the system detects a loss in light signal or receives a safety stop request from its Universal Safety Stop Interface (USSI) input. Each channel can control several fiber optic Safety Interlock Switches in the same fiber loop. Each channel can monitor a separate part of a machine, such as doors, entry gates and sensors. USSI connects multiple PICO-GUARD Controllers and other safety devices in a single safety circuit, when required. Controllers are available with optical channel auxiliary outputs and muting. Fiber optic safety interlocks are available to solve numerous applications and include Grids, Points and Interlock Switches. Diverse-redundant and self-checking design exceeds control reliability and meets Safety Category 4 per ISO 13849 (EN 954-1) and IEC 61496-1 Type 4 requirements
