Supply: 24VAC/DC to 230 VAC/DC +/-15 %, 50/60Hz; 4,65 VA Wiring plan: UR3274U5 UR3274Ux This small universal controller is a compact all-rounder. With the universal input for the most common temperature sensors and process signals combined with the universal power supply and the newest programming and control technologies, this small PIDcontroller is the best solution for sophisticated applications. Beside the excellent price/performance-ratio, this controller convinces with his robust housing and brilliant display. Display: 2-line LED-Display Upper line: Process value, 4-digit, green with 10.2 mm digits Lower line: Setpoint, 4-digit, red with 7,6 mm digits UR3274U6 Indicators: Six red indicators for relais outputs, alarm status, serial communication and tuning. 1 ON, when output active. For electronic valves. ON, when the valve opens and blinking when valve closes. 2, 3 ON, when alarm is active M ON, when the function "manual" is switched on T ON, when controller is in "autotune" mode R ON when serial communication is active Protection class: IP65 from the front (with rubber sealing), back plane IP20. Buttons: 4 push buttons for programming and setting up the setpoints. Connection: Via terminal block. Input ranges: Configuration of the input signal via software or push buttons. Thermocouples type K, S, R, J; internal cold junction (from 0 C to 50 C; accurracy of cold junction 0,1 C/C) RTD: 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 6/150 kOhm Accurracy: Tolerance at 25 C +/-0.2 % 1 digit for thermocouple input, RTD input and analogue input signal. Housing: Black and robust plastic case. The electronics can be pulled out of the front. Dimensions: W 77 mm x H 35 mm x D 53 mm. Panel cut out 28,5 mm x 70,5 mm. Ambient conditions: Operating temperature: 0 C to +45 C; relative humidity 35 % to 95 %. rF, non condensing. Weight: 112 gramms. Scope of delivery: Controller, mounting clamp, sealing, manual. Functionality: Control algorithms: ON - OFF with hysteresis, P., P.I., P.I.D., P.D. time proportioned, dead band. Additionally open / close logic for motorized valves. Measuring rate: Programmable up to 4,1 msec. (242 Hz). Tuning: Manual or automatic tuning selectable. User input: (only available for thermocouple or process signal input) switchable via contact input signal. Alternative usable functions: Hold/freeze values, selecting setpoint 1 to 2. Alarm modes: Absolute / Threshold, band, High / Low deviation. Alarm with optional manual reset . Relay output: 1 change over relay with 8 A @ 250 VAC and 1 closing contact (UR3274U5) with 5 A @ 250 VAC. Programmable as controller output for heating/cooling and/or alarm. Second controller output (cooling): Programmable instead of alarm output with P., P.I., P.I.D., P.D. time proportioned with dead band. Timer function: Controller function + single / double Timer. SSR output: SSR output 12 VDC @ 30 mA. Programmable as controller output for heating/cooling and/or alarm. Copyright by Wachendorff Prozesstechnik GmbH & Co.
