Chapter 6 Installing the EX2 expansion module

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

Universal inputs

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

Binary outputs

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.

Analog outputs (UUKL nondedicated only)

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

•0–10 Vdc

•0–20 mA

Analog output and universal input setup

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.
