Operation as a Fast ON/OFF Controller or Supervisory Monitor
With the optional dual solid state relay output option,
which has a typical response time of only 17 ms,
Laureate temperature meters and transmitters can
serve as extremely fast and accurate ON/OFF con-
trollers for closed-loop temperature control. They
can also serve as supervisory process monitors and
provide alarms or shutoffs when processes exceed
normal limits. Multiple setpoint operating modes are individually
selectable for each relay. Relay duty cycles and
chatter can be minimized with programmable
hysteresis and time delays. A band deviation
operating mode can be selected for each relay,
where an alarm is generated whenever the reading
is a selected number of counts above or below the
setpoint. The relay modes are non-latching.
