To wire several normally open sensors to one Dry Contact input, connect them
in parallel. To do this, take one lead from each sensor and attach it one of the Dry
Contact Input terminals. Then take the second lead from each sensor and attach it
to the corresponding ground terminal. See Figure 8.

The Cell682 has 6 Analog inputs that can be used to monitor 2.8K or 10K
Thermistors (temperature) or 4–20mA transducers. Analog transducers are wired
to the terminals labeled A1 through A6. The corresponding Ground terminals are
located on the lower level terminal strip. The input must be configured by setting
the corresponding jumper in either the Temperature or 4–20mA position. See fig-
