The Tesira EX-LOGIC is a half-rack logic box for use with Tesira SERVER, SERVER-IO, TesiraFORTÉ, IDH-1 and OH-1 devices.
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. Pins 1 – 12 are designated as Logic connections only and will accept contact closure or 5V TTL for input or provide contact closure or LED power (5V/10mA) for output. The remaining 4 connections can also be used for Logic connection or as variable voltage control input (e.g. interface to a potentiometer). Please review the Logic I/O Wiring section for more details.
