The Dionex Inuvion IC System provides two TTL outputs and two relay contacts for control of functions in external devices, such as an integrator or autosampler. The relay outputs can be used to switch any low-voltage control. Switched current must be less than 200 mA and 60 V peak blocking. The relay-contact closures are normally open. When the relay is closed, current flows to the connected device.
IMPORTANT
Relay loads in excess of 200 mA, or with included power supplies over 60 V, may damage the relay drivers on the CPU.
The TTL outputs are normally at 5 V. Setting a TTL output to 0 V turns on the action in the connected device.
The TTL and relay output states can be controlled by issuing direct control commands from the Inuvion ePanel in Chromeleon CDS or by including the commands in an instrument method.
