Designation Explanation
A1 +24V control input with active error ac-
knowledgment
A2 0 V (GND)
A1' +24V control input without active error
acknowledgment
M1 Signal output (PNP)
31 +24V diagnostics input
32 Diagnostic output +24V
13F Enabling current path - input with 5AT
fuse

TBUS Routing of the diagnostic supply voltage
Connect at most 10 devices in series via the
TBUS DIN rail connector.
Confirmation current path 31/32 (N/C contact)
is not an electrically isolated current path and
may only be connected to a maximum voltage
of 26.4V in relation to A2.
