The Tesira EX-LOGIC is a half-rack logic box for use with Tesira audio DSPs. The EX-LOGIC provides both logic inputs and outputs and, through software, can be configured as a control interface.

There are 16 total connections that can be used as inputs or outputs. 12 of the connections are designed as logic connections only and will accept contact closure or 5V TTL for input or provide a maximum of 40V/500mA for output. The remaining four connections can also be used for logic connections or as variable voltage control inputs (e.g. interface to a potentiometer).

The EX-LOGIC also provides a serial port for the output of command strings that can be used to send action commands to other equipment in the system. The EX-LOGIC communicates over Ethernet with the Tesira control network for data transmission, configuration and control, and is powered by PoE (IEEE 802.3at Class 1, 4W).

The Tesira EX-LOGIC complies with the United States Trade Agreement Act (TAA), allowing it to be included in GSA Schedule contractors’ sales bids for the U.S. federal government.
