Trane BAS-APG001-EN Manuel D’Utilisation

The EX2 module has four binary outputs, four analog outputs, and six 
universal inputs.

Each of the six universal inputs may be configured as binary.

The four binary outputs are form A (SPST) relay outputs. These relays 
are not dry contacts; they switch 24 Vac. A pilot relay is required for any 
application using dry contacts. Relays connected to the binary outputs on 
the EX2 cannot exceed 6 VA or 0.25 A current draw at 24 Vac.

Each of the four analog outputs may be configured as either of the 
following:

0–10 Vdc

0–20 mA

Configure each analog output and universal input using a LonTalk

 

ser-

vice tool, such as Trane’s Rover service tool. The service tool requires the 
Tracer MP581 software plug-in to configure an EX2. EX2 modules receive 
their configuration information from the Tracer MP581 controller they 
communicate with. You can do online configuration with the Rover ser-
vice tool, or you can do offline configuration with Rover Configuration 
Builder. In either case, the EX2 modules will not receive their configura-
tion until they are communicating with a configured Tracer MP581 con-
troller.

The inputs are factory configured to be not used. Analog outputs are con-
figured for voltage. Figure 51 on page 95 shows how to wire some common 
sensor types and output devices.
