• Power supply unit SELV (safety extra low voltage) / PELV (protected extra low voltage) conforming to the EMC Directive and Low-voltage Directive (In case CE Marking conformity is required.)
• Power supply unit conforming to the Low-voltage Directive and with an output of 100 VA or less
• Power supply unit with an output holding time of 20 ms or more.
• Power supply unit SELV (safety extra low voltage) / PELV (protected extra low voltage) conforming to the EMC Regulations and Low-voltage Regulations (In case UKCA Marking conformity is required.)
• Power supply unit corresponding to CLASS 2 (In case C-TÜV US Listing Mark conformity is required.)
3) Do not use or store this device in a pressurized environment beyond the atmospheric pressure at sea level.
4) PFHD: Probability of dangerous failure per hour, MTTFD: Mean time to dangerous failure (in years)
With built-in RS-485, SF-C21 can read out its status, error history, etc. to an external device such as a general-purpose PLC, using the MODBUS RTU protocol.
Up to eight SF-C21 units can communicate with the external device as the master station.
The communication preference of MODBUS RTU is set with the DIP switch on the main unit or the software tool “Configurator SF-C”.
Types of data that can be read out
• Status (HIGH, LOW) of safety input and reset / EDM output
• Status (HIGH, LOW) of control output, auxiliary output, and muting indicator output
• Lockout history
• Logic No. change history
