8 safe digital inputs, sink circuit8 pulse outputsSoftware input filter configurable for each channel4 safe digital outputs, output type B with 2 A, source circuitNode number switches for setting the X2X Link addressIntegrated output protection The module is equipped with 8 safe digital inputs and 4 safe digital outputs. They are 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 node number switch for setting the X2X Link address is a unique feature. When modular machine configurations change, it is necessary, for example, to define specific module groups at a fixed address that is independent of the preceding modules in the line. All subsequent standard modules refer to this offset and use it automatically for addressing purposes.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.
