6 safe digital inputs, sink circuit 6 pulse outputs Software input filter configurable for each channel 2 safe digital outputs, output type B with 0.5 A, source circuit Integrated output protection The module is equipped with 6 safe digital inputs and 2 safe digital outputs.
It is designed for a nominal voltage of 24 VDC.
The module can be used to read in digital signals and to control 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.
The outputs are designed using semiconductor technology so that the safety-related characteristics do not depend on the number of operating cycles.
The "high-side high-side" variant (output type B) is required for actuators with reference potential (e.g.
Enable inputs on frequency inverters). It is important to observe the special notices for the cabling in this case.
Safe digital output channels provide protection against automatic restart when network errors occur.
This module is designed for X20 12-pin terminal blocks.
