Product discontinuation:
The Wachendorff UR3274U universal controllers have been discontinued as of 31.12.2020. Therefore, only the devices listed below are still available in certain quantities. If the device you are looking for is no longer available, please contact our application consultants. We will be happy to advise you on alternatives.
This small universal controller is a compact all-rounder. With a universal input for almost all commercially available temperature sensors, potentiometers and process signals, a universal power supply and modern programming, operating and control technologies, this controller is the ideal solution for demanding applications. In addition to an excellent price/performance ratio and high quality, the controller impresses with its robust, compact housing and brilliant display.
Display:
2-line LED display
Upper line: Actual value, 4-digit, green with 10.2 mm digits
Lower line: setpoint, 4 digits, red with 7.6 mm digits
Indicators:
Six red indicators for control outputs, alarm statuses,
serial communication and tuning.
1 ON when output is active.
For electric control valves ON when valve opens and flashing when valve closes.
2, 3 ON when an alarm is present.
M ON if the "manual" function is switched on.
T ON when the controller is running in the "Autotune" cycle.
R ON for serial communication.
Entrance areas:
Setting the input signal in the software or via the keypad.
Thermocouple type K,S,R, J; reference junction: internal (from 0 °C to 50 °C; reference junction accuracy 0.1 °C/°C)
Temperature sensors: Pt100, Pt500, Pt1000, Ni100, PTC1K, NTC10K
Linear inputs: 0 V to 10 V, 0/4 mA to 20 mA, 0 mV to 40 mV
Potentiometer: 1 kOhm to 6/160 kOhm
Accuracy:
Tolerance at 25 °C +/-0.2 % ± 1 digit for thermocouple input
Thermocouple input, temperature sensor and analog signal.
Relay output:
1 changeover relay with 8 A at 250 VAC and 1 normally open contact (UR3274U5) with 5 A at 250 VAC.
Programmable as control output for heating/cooling or alarm.
SSR output:
SSR output 12VDC at max. 30 mA.
Programmable as control output for heating/cooling or alarm.
Power supply:
24 VAC/DC to 230 VAC/DC +/-15 %, 50/60 Hz, 4.65 VA
Ambient conditions:
Operating temperature: 0 °C to +45 °C;
Relative humidity 35 % to 95 % rH, non-condensing.
Programming:
Programming and operation is menu-driven
menu-guided via the front buttons. With the programming kit, the
controller can also be programmed using Windows ™ software.
This software is compatible with Windows 7 and Windows 10.
The memory card has an internal battery. This makes it possible to
devices can be programmed without connecting the power supply
(up to 1000 programings with one battery).
Functionality:
The basic version includes a control output for two-point control
(with hysteresis) with P, PI, PD and PID behavior is included. The
output is time-proportional. In addition, a cycle control
for a control valve can be programmed.
Alarm operating modes:
They switch when the temperature exceeds or falls below the
temperature or deviation; band alarm; limit value or continuous
continuous signal switching.
Standby and hysteresis programmable.
In the event of sensor breakage: Reaction as for overtemperature.
Second control output (cooling)
programmable instead of the alarm output: With P, I, PI, PD and PID behavior. The output is time-proportional. Switching cycle, ratio to heating, overlap or deadband are programmable.
Housing:
Black, impact-resistant plastic housing W 77 mm x H 35 mm x D 53 mm. Panel cut-out: 28.5 mm x 70.5 mm.
Certificates:
CE, RoHS
Customs tariff number:
8542 31 90
