Making Screw Terminal Connections with External Devices 43
Pressure +/– and
Chart +/– (Analog
Output)
Produces a DC voltage whose magnitude is proportional to the
physical parameter being monitored. The voltage range of the
analog output is 0 to 10 mV full scale.
Pressure Terminals - Transmit a voltage representation of the
current 600E system backpressure. This is a direct pressure trace
from the pump transducer (0 to 6000 psi is full scale), where 10
mV = 6000 psi.
Chart Terminals - Transmit a voltage that is proportional to the
specified Chart monitor function:
• Composition of an eluent reservoir (A, B, C, or D)
• Current flow rate
• Column heater temperature (0 to 99 °C)
You select the Chart function to monitor using the controller Pump
Setup screen (as described in the Waters 600E Multisolvent
Delivery System User’s Guide).
AUX +12 V
(Digital Output)
Provides up to 1.2 A of current at +12 VDC. The Aux +12 V signal
is used in conjunction with output switches S1 through S4 for
applications such as powering solenoid valves and other automa-
tion accessories..

Attention: Applying externally generated voltages may
damage the instrument. Shorting the Aux 12 V terminal
to ground or an event output will cause the Aux +12 V
power fuse to blow.
