S5-95F Installing and Connecting the Basic System
Example: Failsafe Connection of an Actuator with Direct Triggering (Type K)
Connect the 24 V DC load voltage (L+ potential to terminal 1, L- potential to terminal 10).
With direct triggering, the load voltage for subunit A and for subunit B must be supplied by one
voltage source.
Connect the actuator to the output selected.
The actuator receives the L+ potential from the first subunit and the L- potential from the other
subunit (P-M triggering). When connecting the DQ, make sure that one bit is assigned different
terminals in "A" and "B".
