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 extre-
mely fast and accurate ON/OFF controllers
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.
