Material number:
  • 6 safe relay outputs
  • Output type "Relay"
  • Relay module for 230 VAC / 24 VDC
  • Switching current 6 A
  • Normally open contact
  • Single-channel isolated outputs

This module is equipped with 6 safe relay outputs.

The module can be used for controlling floating actuators in safety-related applications up to PL e or SIL 3.

Safety relays are installed in the module. The positively driven feedback contacts are evaluated internally by the module. Safe digital output channels provide protection against automatic restart when network errors occur.

This module is designed for X20 12-pin terminal blocks.
