Description
Description
Housed in a wall-mount, watertightplastic enclosure, the CN1511 is aflexible temperature controller thatoffers the ease of an on/offcontroller with the precision of afull-blown PID controller. Forapplications that do not require thecomplexity of PID control, this device can be programmed to work assimple on/off controller. Yet forprocesses that require closetemperature conformity, theCN1511 can be run under full PIDcontrol, selectable for either heating(direct acting) or cooling (reverseacting).
The CN1511 accepts 5 differentramp and soak programs, each withup to 10 segments. Separatepass-codes are required forselecting or entering a ramp/soakprogram. This prevents operatorsfrom making any inadvertentchanges. The manual hold featureallows for an indefinite holdanywhere along the ramp/soakprofile. Also offered is a manualsetpoint entry mode for a quickramp-to-setpoint function. Thiseliminates the need to enter acomplete ramp/soak program.
Maximum and minimumtemperature readings arecontinuously tracked, and 4 optionalprocess alarms are available. Theseare programmable over the entirerange of the selected input type. They can be configured as latchingor non-latching, normally open, ornormally closed. There are also2 optional timers that workindependently or in conjunction withprocess limits (e.g., turning on a fan10 minutes after limit 1 temperatureis reached). The time function keepstrack of process run time.
The CN1511 also functions as arate monitor, indicatinginstantaneous as well as averagerate of temperature change. Aprogrammable time base allows therate to be displayed in per second,minute, hour, or any other interval.The CN1511 can also beprogrammed for a rate alarm, whichcan indicate whether a predeterminedrate is exceeded or not achieved.
Additional features include a built-inbuzzer that sounds whenever a limitis reached (available with the relayoption). Visual indication of relayoutput status is given by LEDs onthe front panel. The CN1511 alsohas a power line filter, designed toprovide trouble-free operation inharsh industrial environments.
