2.2 Controller R 400-P
Ambient temperature (°C) 5...40
Control range (°C) -65...305
Temperature setting/
Resolution (°C) membrane keypad with 16 keys, setpoint input with 0.01°C resolution
Temperature measurement (bath) built-in digital thermometer with 0.01°C resolution; accuracy and stability of measurement
(electronics without probe) better than 0.05 %
±
0.05 K*).Temperature probe Pt 100 to
DIN IEC 751, Class B, can be calibrated additively at each measurement point.
External temperature measurement 2 separate temperature measurement circuits for external Pt 100 to DIN EN 60751 in 4-wire
circuit, accuracy and stability of measurement better than 0.05 %
±
0.05 K*),
can be calibrated additively at each measurement point. One probe produces the
measurement for external control.
Display back-lit LCD matrix display, 2 lines with 16 signs each, 10 mm character height
Temperature control modified PID controller with automatic structure selection. Control parameters through auto-
adaptation or manual input.With external control a cascade controller operates on the
measurement of one of the two external circuits (T
1
or T
2
).
Heating actuator triac zero crossing with full wave PWM,
capacity max. 3 kW or 14 A
Triggering for triac control of control valve for cooling water solenoid valve 230 V; 50/60 Hz, max. 0.2 A
