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.
