FIGURE 28: UNIVERSAL OUTPUT WIRING
RELAY OUTPUTS
Starting with Revision E, SMART-Space Controllers use latching relays for both
jumper-selectable and fixed relay outputs. The relays provide normally open dry contacts,
rated for continuous loads up to 500mA. Relay outputs switch to the 'open' or 'off' state
upon failure of controller power.
Figure 29 shows the typical Relay output wiring for an SSC or SSCE. The output terminals
are completely isolated between outputs, and from the power connections. For this
reason, SSC and SSCE models can switch any mix of DC and AC loads.
