Alarm Interface Card ~ Terminals & Pin-out
The Smartpack controller's alarm and digital input monitoring signals are accessible from the
controller's rear panel, on mini power connector CON1 (2 outputs & 2 inputs).
Using the Alarm Interface Card (Art. 218470) plugged to Smartpack's CON1, you can make the
signals on CON1 accessible on terminal block X1.
For detailed information about the card's pin-out location and terminal block connections, see the
figures in this section.

Quick Start Guide Minipack PS System
The alarm outputs in Minipack systems use the Fail-Safe
Operation Mode (relay coils energized in the system's
+
normal operation mode). When the system is in alarm mode,
the alarm relay coils are de-energized.

The figure shows the position of the relay contacts when the PS
system is in alarm mode of operation; the relay coils are then de-
