Designed to meet new functional safety Certifications Listed and TV standards, such as EN ISO 13849-1 and EN 62061, the new family offers key functions to simplify installation and system complexity. A Functional Safety Data See next page broad range of safety devices such as safety interlock switches, Power Supply emergency stop devices, pressure sensitive safety mats, and OSSD Input Power Entry 24V DC (-15+10%) devices such as safety light curtains are all compatible with the DI/SI: 2.5 W same relay without additional configuration.The functionality of two DIS: 2 W standard safety relays can be achieved in one Dual Input (DI) device, Power Consumption CI/EM/EMD: 3.5 W allowing connection of two dual-channel input devices into one GLP: 2.5 W safety relay. Inputs A TV-approved single rotary switch sets the required function of DI/DIS: 2 dual N.C., 2 dual OSSD, or safety the safety relay and eliminates the typical redundant switch setting mats and 1 single-wire safety input process. Selectable functions include simple logic, reset, timing, and SI/CI: 1 dual N.C., 1 dual OSSD, or safety mats Safety Inputs GLP: 1 dual N.C. or 1 dual OSSD and 1 diagnostics. single/wire safety The single-wire safety connection simplifies cascading and EM/EMD: 1 single-wire safety input expanding safety functions by linking relays with a single-wire Input Simultaneity Infinite connection.
