Siemens 3SK1121-1CB42 SIRIUS 3SK1 Advanced Safety Relays

Technical Specification

Features:
  • Make: Siemens
  • Model code: 3SK1121-1CB42
  • Control Voltage: 24 V DC
Additional info:

With SIRIUS 3SK1 safety relays, safety functions can be simply parameterized with DIP switches. Operation of a sensor is always followed by fail-safe disabling of all outputs of these basic units. Seamless integration: reduces wiring effort for fail-safe SIRIUS 3RM1 motor starters More free space: fewer basic units and main circuit components Extremely compact: narrow overall width and multifunctionality
