1 General information
The modules are equipped with 6 safe digital inputs and 2 safe digital outputs. They are designed for a nominal
voltage of 24 VDC.
The modules can be used to read in digital signals and control actuators in safety-related applications up to PL
e or SIL 3.
The modules are equipped with filters that are individually configurable for switch-on and switch-off behavior. The
modules also provide 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 switching 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 wiring in this case. Safe digital output modules are equipped with protection against automatic restart in the
event of network errors.
These modules are designed for X20 16-pin terminal blocks.
• 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
