KL1352 | Bus Terminal, 2-channel digital input, NAMUR

The KL1352 digital input terminal analyzes the input signal of NAMUR sensors according to IEC 60947-5-6. The Bus Terminal has two channels. In addition to the display of the signal state from the sensor, short circuit or open circuit is also detected. The LEDs display the signal states or any error states.

 

Special features:

  • direct connection of NAMUR sensors according to IEC 60947-5-6
  • possibility to diagnose open circuit and short circuit

Product status:

regular delivery
