Overview

The safety module has numerous digital inputs and outputs for the connection of passive and active
sensors. Safety functions are requested via two-channel, safe inputs.
For the following descriptions, it is necessary to define some terms:

Meaning
Maximum time, during which the two channels of a safe input may be in anti­
valent statuses, without the safety engineering triggering an error response.
Time during which the interfering pulses and test pulses, such as those from
connected active sensors, are not detected.
The function of the inputs can be freely configured in broad ranges. During
configuration, the user must ensure that the safe status is achieved on de-
energised inputs (comply with idle current principle!).
The function of the inputs can be freely configured in broad ranges. Control
functions require active actuation / switching of the control input with 24 V,
in order to trigger the desired reaction (example: Error acknowledgement,
restart, mode selection switch). The idle current principle would not be safe
for this!
A safe input consists of two control cables, which both switch HIGH or LOW
simultaneously (equally-switching inputs).
A safe input consists of two control cables, which both switch HIGH or LOW
against one another. At any time (with the exception of the discrepancy time)
only one input is simultaneously HIGH or LOW (unequally-switching inputs).
Description
Max. input voltage, sine or cosine signal
Vector length root(sin² + cos²) min.
Vector length root(sin² + cos²) max.
Maximum time during which a signal may be out­
side the limit, before an error is triggered.
