Barnant Temperature Controller
- Direct plug-in of heating devices
- Adjustable over-temperature and loop break cutoff give fail-safe operation
- 3 control modes: on/off, autotune PID, programmable PID
- Field calibration offset compensates for probe error
- Deluxe Model features ramp & soak profiles and RS-232 communications for computer control of system parameters, FREE software included
Temperature Controller from Barnant is new and designed for a wide variety of temperature control applications. Choose from standard or deluxe models. Both controller models provide excellent control accuracy and power capabilities, making them ideal for pilot process plants, R & D labs or OEM requirements. Use as a benchtop controller or panel mount with the optional panel mount kit, sold separately.
Temperature Controller models accept; J, K, T, E, N, B, R or S thermocouple types with miniconnectors. Deluxe model also accepts 400 & 700 series thermistor probes with 1/4", phono plug or RTD probes with 3-pin connectors, adapters available upon request.
Temperature Controller
Features - Rear panel output receptacle for direct plug-in of heaters and other devices. Field Calibration - improve system accuracy by entering offset value to correct for individual probe error. View set-up and operational parameters on two line alphanumeric display for easy programming. Temperature Scales - °C, °F, K (Kelvin), °R (Rankine) or Reaumur. Non-volatile memory stores set-up parameters, if power is lost parameters are saved.
Temperature Controller
Alarms - Fully Programmable; choose from alarms off, manual reset (via front panel push button) or automatic reset. Set either a High, Low or a High/Low process alarm; or a deviation alarm as a High, Low, High/Low or Band. All alarms feature adjustable hysteresis and an audible alarm option. Deluxe model includes SPDT alarm relay.
Temperature Controller
Safety Features - Output power to load device automatically shuts down in the event of a broken sensor or control loop break. Over Temperature Protection shuts down the system if OTP setpoint is exceeded. Output power receptacle is fused separately for added safety.
Temperature Controller - Standard Model has a 115/230 VAC, 10A (1150-2300 watts) max heater output. Select from three control modes: On/Off, Autotune for standard PID applications or Programmable PID for non-standard PID applications. Front Panel LEDs indicate status of output alarms.
Temperature Controller - Delux Model has all the features of the standard controller plus: higher heater output capacity of 115/230 VAC, 15A (1 725/3450 watts) max, program up to nine ramp and soak profiles for more complicated processes, bidirectional RS-232 computer interface with selectable baud rates (300 to 9600), A WINDOWS® software program (system requirements are 386 computer or better, WINDOWS 3.1 or later, EGA, VGA, or compatible monitor). Deluxe model also features an isolated 4-20 mA output, scalable for positive or negative slope, 250 ohm resistor is included for conversion to a 1- 5 V output signal, output connector included.
Both 115 VAC Temperature Controllers come with a 6-ft power cord. 230 VAC models include European style power cord set and power output connector. NEMA and country specific 230 VAC cord sets are available upon request.
Probes not included, order separately.
