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.
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
Eight red indicators for relais outputs, alarm status, serial
communication and tuning..
C1, C2 ON, when output is active.
C1 as relay/SSR/mA/voltoutput or C1 (opening)
and C2 (closing) for electronic valves
A1,A2,A3 ON, when alarm is active
MAN ON, when the function “manual” is switched on
TUN ON, when controller is in “autotune” mode
REM ON when serial communication is active
3 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.

Second controller output (cooling):
The controller will be programmed via push buttons or
Windows™-software. The memory card is battery powered. With this
technology you can programm the controller without powering it up (up
to 1000 programm cycles with one battery).
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
Manual or automatic tuning selectable.
Absolute / Threshold, band, High / Low deviation.
Alarm with optional manual reset .
Standby and hysteresis programmable
Programmable instead of
alarm output with P., P.I., P.I.D., P.D. time proportioned with dead
