TB-7/TB-10 – General Purpose Output Relay Connections
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 12, and Figures 18 and 19
on page 26, and make the following wiring and transorb connections.
