10164-L Sampler Control Cable for use
with Isco and Sigma Autosamplers
1. General
The 10164-L sampler control cable enables a datalogger to trigger an Isco,
American Sigma, or connector-compatible autosampler. Through this cable,
the datalogger can inhibit the sampler from running its programmed sampling
routine and sense and record when the sampler indicates that it has taken a
sample. Each of these functions is independent of the others and may be
combined as desired.
2. Specifications
Sampler Connection: mil-spec, 6-pin circular connector (shell size 14)
Datalogger Connection: pigtail with individual conductors
Current Drain: < 1 mA; consult the specifications of the connected
sampler to determine its power considerations.
Cable Length: 50 ft standard; 1000 ft maximum (see Cable Length
Considerations)
2.1 Cable Length Considerations
In most applications, the 10164 cable connects the datalogger to a sampler
residing in the same instrumentation shack. Therefore, a cable length of 50 ft
or less is typically used.
Cable lengths up to 1000 ft are possible if the sampler supports long event
markers. For example, the Isco-brand sampler has a 3 second event marker,
which is an adequate duration for a 1000 ft cable length.
The 10164 does not include surge protection. Therefore,
longer cables need to be protected from surges in order to
safeguard the system from electrical transients. A
recommended method of doing this is to place the cable in
a metal conduit and then bury the conduit at a depth of at
least one foot.
