For a wide variety of temperature control applications
• Direct plug-in of heating devices
• Adjustable over-temperature and loop break cut-off for fail-safe operation
• Three controller modes: on/off, autotune PID and programmable PID
• Field calibration offset compensates for probe error
Controllers accept J, K, T, E, N, B, R or S thermocouple types with miniconnectors. Rear panel output receptacle allows direct plug-in of heaters and other devices. Set-up and operational parameters can be viewed on the two-line alphanumeric display for easy programming. Units can display temperature in °C, °F, K (Kelvin) or R (Rankine) scales. Non-volatile memory stores set-up parameters even if power is lost. Alarms can be programmed for high, low or high/low process or a deviation alarm as a high, low, high/low or band. All alarms feature adjustable hysteresis and an audible alarm option.
The standard controller (9339A09) has a 115 VAC, 10A (1150 Watts) maximum heater output. Front panel LEDs indicate status of output alarms.
The deluxe controller (9339A11) has a higher heater output capacity of 115 VAC, 15 A (1,725 Watts). Unit can be programmed with up to nine ramp and soak profiles for more complicated processes. The bi-directional RS 232 computer interface has selectable baud rates (300 to 9600) and includes software. Deluxe model also features an isolated 4-20 mA output, scalable for positive or negative slope; 250 ohm resistor for conversion to a 1-5 V output signal; an output connector; and a SDPT alarm relay. Unit can also accept 400 & 700 series thermistor probes with 1/4" phono plug or RTD with 3-pin connectors.
