The TTL and Relay connector strip provides two TTL outputs, two relay outputs, and four TTL inputs. The outputs can be used to control functions in other TTL- or relay-controllable devices. The inputs can be used to switch the injection valve position, turn on the pump, perform an autozero command, and send an event mark to the analog output. For more details, see TTL and relay control.

WARNING

Use only Thermo Scientific twisted-pair wires (P/N 043598) for TTL/relay connections. Excessive cable length can increase RF electromagnetic emissions or affect the sensitivity of the Dionex Inuvion IC System.
