Universal power supply
Universal input für process signals, thermocouple, RTD
2-line LED display
Easy programming via software or push buttons
Two setpoints as relay or relay/SSR
PID-Controller in 32 x 74 mm format
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 PID-
controller is the best solution for sophisticated applications.
Beside the excellent price/performance-ratio, this controller
convinces with his robust housing and brilliant display.
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
4 push buttons for programming and setting up the
setpoints.
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
Tolerance at 25 °C +/-0.2 % ± 1 digit for thermocouple
input, RTD input and analogue input signal.
Programmable up to 4,1 msec. (242 Hz).
(only available for thermocouple or process signal input)
switchable via contact input signal.
Alternative usable functions: Hold/freeze values, selecting setpoint 1
to 2.
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.
SSR output 12 VDC @ 30 mA.
Programmable as controller output for heating/cooling and/or alarm.
