TB10 – General Purpose Output Relay Connections
If output relays three and four have not been configured for use for door held open annunciation (as
described in the previous section) they are available for general-purpose use. General-Purpose
Output Relays are Form C relays that provide an output to enable or disable a device outside the
controller. This device can be attached to the relay's normally closed circuit so that the device is
always on until the relay energizes to open the circuit and turn it off. Or, this device can be attached
to the relay's normally open circuit so that the device is always off until the relay energizes to turn it
on.
Depending upon the type of device being installed and your application, the device may require a
normally closed/common connection, a normally open/common connection, or a normally
closed/common/normally open connection. Every application requires the common lead connection.
Please refer to the General-Purpose Output Relay section on page 14 for more information on
General-Purpose relay outputs and output devices.
For examples of typical general-purpose relay installations, refer to Table 10, Figure 15, and Figure
16, all on page 23, and make the following wiring and transorb connections.
