Figure 12-52: The OE322 Three Relay Expansion
Board
This Three Relay Expansion Board uses an 8-position modular
plug to connect to the TUC-2R controller.
The Three Relay Expansion Board is an expansion board for the
TUC-2R controller. It provides a means to add 3 additional output
relays to the TUC-2R controller. Again, control of these relays is
application specifi c, meaning that the software code in the TUC-
2R must have been written to support the Three Relay Expansion
Board. This board is typically used to control pilot duty relays that
control Series Fan, Parallel Fan, up to 2 stages of Box heat, and
external Strip Heat. This 3 Relay output board also has a 0-to-
10 volt DC analog output for control of an external valve, for hot
water/chilled water control.

Figure 12-53: Damper Actuator – with the connection
cable to connect to the TUC-2R Controller
This Damper Actuator uses a 6-position modular plug to connect
to the TUC-2R controller. Control of 60 Degree or 90 Degree
dampers is supported on the TUC-2R controller with this actuator.
