5.1.2 Relay Wiring
Figure 234. 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) or normally
closed (NC) contacts.
