All relays can be used to drive logic or control external circuitry.
Figure 74. Relay Tally and GPI Output Connection Example
Although the diagram shows mechanical relays, the actual outputs are
implemented with solid state relays. The solid state relays are bidirectional;
either polarity voltage can be applied. If the switcher GPI/Relay Tally
outputs are used to drive downstream DC relays, be sure to install diodes
across the relay coils to clamp inductive spikes. Shielded cable is recom-
