SF-C safety control unit
Specifications for the safety control units
The safety control units allow you to connect and control various safety components for machines. The SF-C10 series is specially designed for connection and control of Panasonic light curtains, while the safety control unit SF-C21 can be used for all kind of safety devices like safety switches, emergency switches, enable grip switches, safety beam sensors, safety scanners, or safety light curtains.
Specifications for the safety control unit SF-C10 series for safety light curtains
|Product No.||Type of control unit||Cables||Description|
• Connection cable: SFB-CB (for SF4B series), SF2B-CB (for SF2B series)
• Extension cable: SFB-CCJ10
|8-core cable with connector to connect to the light curtain. Interference prevention wires and the muting function cannot be used.|
• Extension cable: SFB-CCJ10-MU
|12-core cable with connector to connect to the light curtain. Interference prevention wires can be used. The muting function cannot be used.|
• SFB-CCB (-MU) (for SF4B series), SF2B-CCB (for SF2B series)
• Extension cable: SFB-CC (-MU)
|Use a discrete wire cable to connect the light curtain. Interference prevention wires and muting function can be used. However, the controller SF-C13 itself does not support the muting function.|
|Application expansion unit for the SF4B series||
• Light curtain connection cable: SFB-CB-EX
• Extension cable: SFB-CCJ10
|Equipped with muting function and emergency stop input, thus expanding the applications of the light curtains. Use the exclusive connection cable to connect the unit to the light curtains. (compatible with SF-C14EX handy controller)|
Specifications for the safety control unit SF-C21
The safety control unit SF-C21 can do the work of four safety relay units. Therefore, much less wiring is required. With its compact size (height 97 mm x width 45 mm), it can be installed even in narrow spaces. The status of the safety control unit can be monitored easily with a PLC. The SF-C21 provides four auxiliary semiconductor outputs (PNP). Other automation control devices such as PLCs, HMIs, etc. can monitor of the SF-C21 via RS485 communications (MODBUS RTU) and get information about the status, the selected logic, and possible errors. However, the SF-C21 cannot be controlled by an external device such as a PLC.
Users do not need any programming skills because the safety control unit SF-C21 is equipped with a preset logic. Simply turn the rotary switch to select one of the eight preset logics. They are safety-certified and compatible up to control category 4 PLe.
For users wanting to create a reliable safety circuit, we recommend using our software Configurator SF-C. Again, you do not need any programming skills.
