Description:
  • 2 safe digital inputs, sink circuit
  • 2 pulse outputs
  • Software input filter configurable for each channel
  • 2 safe relay outputs
  • Output type "Relay"
  • Relay module for 48 VAC / 24 VDC
  • Switching current 6 A
  • Normally open contact
  • Single-channel isolated outputs

The module is equipped with 2 safe digital inputs and 2 safe relay outputs. It is designed for a nominal voltage of 24 VDC.

The module can be used to read digital signals and for floating control of actuators in safety-related applications up to PL e or SIL 3.

The module is equipped with filters that are individually configurable for switch-on and switch-off behavior. The module also provides pulse signals for diagnosing the sensor line.

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.
