Safety Relay SIL CL 3
471EFR
Safety Relay SIL CL 3 471EFR
PLe according to EN ISO 13849-1 Four safety outputs (two separate safety circuits each with two safety outputs) Separate control outputs for further processing Emergency stop function with short-circuit detection Suitable for 2-hand control Connection via codable, screwless terminals Available as an option with double terminals LED status display Adjustable delay times for safety output 4 Suitable for sensors with 2 NO system, input 4 also suitable for NO/NC system Monitoring of the contactor externally Use The control unit is for evaluating signals from machine safety sensors. Due to the variable design, the inputs can be used for a variety of functions, such as 2-hand control or for connecting an emergency stop button. Models Safety control unit 471 M41 H31 for 4 to 32 sensors, with safety and control outputs. The 471 M41 H31 enables the connection of a sensor in 3- as well as 4-wire technique. The 4-wire technique also allows a cross short detection. At sensor input 4, a sensor with 2-contact makers as well as a contact maker/breaker system can be connected. Further parameters, such as the delay time, can be configured by a DIP switch. The connection terminals are available as an option and also as double terminals (1.5 mm²).
