  • PLe/SIL3/Cat.4
  • Supply voltage 24V AC and DC
  • Connection for 4 sensors normally open/ normally closed
  • Monitoring of connected contactors (EDM)
  • Very compact design
  • 1 relay safety output potential-free SIL3/PLe/Kat.4
  • 1 control output changeover contact potential-free
  • LEDs for status and error indication

The compact design of the 4621273E safety evaluation unit allows it to be used even in applications with limited space.

A potential-free safety output in SIL3/PLe up to 4A and a control output with change-over contacts up to 3A are available. A maximum of 4 sensors with normally open/ normally closed contacts can be connected. Input expansion units (interfaces) can’t be used. Due to the 24V AC and DC supply voltage, the unit can be used for a wide range of applications.

The 4621273E can be used as a pin-compatible replacement for
