Description
2 safe digital inputs, sink circuit2 pulse outputsSoftware input filter configurable for each channel2 safe relay outputsOutput type “Relay”Relay module for 48 VAC / 24 VDCSwitching current 6 ANormally open contactSingle-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.
