3.5. Discrete Controlled Inputs
The actuator can be controlled by discrete inputs: two-wire control, three-wire control, four-
wire control, and multi-port valve control. Connect the power for these discrete inputs as
detailed in Table 3-1 for external power source. Table 3-2 details connections for the
internal power source. See Section 3.3, Electrical Connections for general electrical
connection requirements.

3.6. Auxiliary Control Module (ACM) – Optional
The ACM is an optional module used to expand the functionality of the TEC 2000 Actuator.
There are several versions of the ACM available: Futronic, Controlinc, and Auxiliary Relay
Module (ARM). The Futronic ACM may be used alone or with the ARM stacked on top. The
Controlinc ACM is used with a Communication Adapter Module (CAM). The ARM may also
be installed alone. Each ACM can be supplied with the TEC 2000 Actuator or provided later
as an upgrade.
