Panasonic SF-C21 Configurable Safety Controller
The Panasonic SF-C21 Configurable Safety Controller is a safety control unit that can do the work of up to four safety relay units. Its compact size allows it to be installed in narrow spaces up to 45 mm wide.
Equipped with eight single or four dual Safety Inputs and four single or two dual PNP transistor safety outputs, the unit is capable of safety functions incorporating two-handed control, parallel muting, sequential muting, category 0 and 1 stop, as well as logic utilising AND/OR functions. Using Modbus RTU protocol over RS485 communications, various general-purpose control units such as PLCs or HMIs can monitor the SF-C21 status, the selected logic and any error status.
The unit has flexible configuration features, which allow the user to either select one of the eight predefined, safety-certified logic scenarios using the rotary switch on the front panel or configure a unique scenario to suit the user’s application using the free software.
The Configurator SF-C software is safety certified and has a simulation mode to test if the logic and safety circuit prepared by the user operates efficiently.
The product complies with safety standards Category 4/PLe to EN ISO 13849-1 and SIL CL 3 according to IEC 62061.
