Figure 23. Switching a relay
Many Functions require the use of relays. Each relay can be wired as
shown in Figure 24. When a channel turns on, it will sink current to
ground, activating the relay coil. Multiple relays can be wired to the
same channel. Each channel can sink a maximum of 750mA of coil
current (
refer to the relay manufacturer’s documentation
). Any type of
relay can be used including solid-state and MDR’s. Relays may be
used to switch large currents, combine signals, or inverse a channel
output with normally open(NO)/closed(NC) contacts.
CAUTION: The relay coil voltage must match the Relay
Driver supply voltage.
