2.2.7.5 Relay Board
Figure 5:
Relay Board
See Figure 5. The Radio Control Equipment provides for relay outputs for control of external
lighting. Either of the two relay sets can be configured for either cumulative (incremental) or,
individual output. See Figure 4 and Figure 5 for a description of the logic used.
All relay contacts are dry, and can switch 48Vdc or 120Vac through either set of
relays for CCR control.
Table 6:
Cumulative (Incremental) Operation
Table 7:
Individual Operation
The output voltage required from the relays (u48V DC or 120V AC) is provided to the
relays through ACom (Terminal Strip #4) for relays A3, A5, A7 or BCom (Terminal Strip #11)
for relays B3, B5, B7. See Table 4.
Configuration Switch SW1 is used to set the operational configuration of the Radio Control
Equipment. See Table 8 for additional information.
