10.2 User Interface
Depending on the model of Relay Card (see Table 20), the relays on the Relay Card will be
configured as SPDT or SPST with or without snubbers. Figure 45 shows these relay configura-
tions.
The diode protects the coil power supply (and the Smart Star backplane) from inductive
spikes caused by energizing/de-energizing the coil, and the resistor-capacitor snubbers
protect the relay contacts against voltage spikes induced by inductive loads.
Figure 46 shows the complete pinout for the user interface on header J1. Note that pin 1 is
indicated by a small arrow on the ribbon cable connector.
