External Low Pressure Valve Outputs
Six outputs allow connection to externally-installed low-pressure (solenoid)
valves. Low-pressure valves can be used for on/off control of liquid flow (for
example, to turn flow on and off from a reagent reservoir). You control the outputs
with Chromeleon or Chromeleon Xpress.
Two low-pressure valves can be installed on a regulator stand and four valves can
be installed on the rear of the DC.
Analog Output, TTL, and Relay Connectors (Optional)
If the I/O option (P/N 062201) is installed, the following connections are
provided:
• Two analog outputs (one for each detector)
• One +5V power output
• Two relay outputs
• Two TTL outputs
• Eight programmable TTL inputs
See Section 2.18
for details about the I/O option.
