10.3 Additional Inputs/Outputs Configuration
10.3.1 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. Refer to the General-Purpose
Output Relay section on page 37 for more information on general-purpose relay
outputs and output devices.
For examples of typical general-purpose relay installations, refer to Table 32, and
Figures 10-14 and 10-15, both on page 88, and make the following wiring and transorb
connections.
