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.
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
Indicators: 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
Buttons: 3 push buttons for programming and setting up the
setpoints.
Input ranges: Configuration of the input signal via software or push
buttons.
