Siemens Input Expansions – 3SK1220 Sensor Expansion/ 3SK1230 Power Supply

October 14, 2019

Siemens 3SK1 Advanced basic units can be made more flexible.The 3SK1220 input expansion allows additional sensors to be integrated easily and flexibly. The device monitors two single-channel sensors or one two-channel sensor, whatever their output technology (floating/single-ended). The 3SK1230 power supply makes the 3SK1 devices universally usable, whatever control supply voltage is to be used. Alongside the 3ZY12 device connector, the 3SK1230 power supply can also be wired to act as a power supply for 3SK1 devices.

  • A wide voltage range of 110 … 240 V AC/DC allows the devices to be used worldwide
  • Low stock keeping due to little variance
  • Flexible expansion of the number of sensors without the need for additional wiring between the devices
  • Perfect adaptation of the number of inputs to suit the application
  • Universal use thanks to the wide range of adjustable parameters for sensor expansion (parameters as for 3SK1 Advanced basic units)
