Line voltage 100 - 240 Vac
Frequency 50 - 60 Hz
Time or user-controllable
switch closures S1 – S4
Four controllable contact closures (two
terminals per closure).
Maximum allowable current = 0.5 A per contact.
Maximum allowable voltage = 30 Vdc. Contact
resistance = 0.2 ohms. Outputs can be
controlled from the I/O events table or directly
from the front panel.
Two modes available from the front panel and
I/O events table: On = contact closed; Off =
contact open. Additional modes available in the
I/O events table: Pulse = single contact closure
for programmable period; Toggle = changes the
current state.
Stop flow (input) Two terminals (+, –) that allow other LC devices
to immediately stop solvent flow.
User-selectable to halt flow on high or low
signal.
Input voltage range: ±30 Vdc. Logic high = >3.0
Vdc ±10%, logic low = <1.9 Vdc ±10%. Minimum
pulse width = 10 msec.
Hold inject (input) Two sets of (+, –) terminals that allow other LC
devices to delay an injection. Boolean operator
selects whether one or both inputs delay the
injection.
Input voltage range: ±30 Vdc. Logic high = > 3.0
Vdc ±10%, logic low = < 1.9 Vdc ±10%. Minimum
pulse width = 10 msec.
