Block diagram
The Block diagram shows variant SCB-04. Other variants differ in output
configuration.
SCB-04: Two safe HL outputs - O1, O2 and two safe relay contacts - 17-18, 27-28.
SCB-03: Three safe HL outputs - O1, O2, O3
SCB-02: Two safe relay contacts - 17-18, 27-28

Application example 1:
SCB-04 for time-delayed switch-off of a drive with safe immediate signal to safe control
for controlled stop with automatic reset
Application example 2:
SCB-02 for filtering limit value transgressions with automatic re-trigger function
