Ultra-Low Refrigerated Circulators
REG+E-PROG (12):
Outputs of the connector
1. First define the desired output value for channels 1 to 3:
ActInt internal actual temperature value (bath temperature)
ActExt ernal actual temperature value (external sensor)
Power periodic or intermittent heating or cooling
Setpoint active setpoint temperature
(Setpoint1, 2, 3,/ integr. programmer /external programmer)
2. Then select the display size for channels 1 to 3:
Voltage outputs channels 1 and 2
Assign the voltage values of 0 V to the lowest and 10 V to the highest
necessary temperature or power rating required as an output value
(°C / %).
Current output channel 3
Assign the current values 0 mA or 4 mA to the lowest and 20 mA to
the highest temperature or power rating required as an output value
(°C / %).
3. The current output (chanell 3) offers 2 ranges for selection:
0 to 20 mA or 4 to 20 mA
0 V
10 °C 210 °C
200 K
197 °C 202 °C
5 K
0 mA 20 mA
4 mA
Examples:
>Chan.1 : ActInt
0V = 10°C
10V = 210°C
lowest temperature value: 10 °C
highest temperature value 210 °C
Fig. shows 200 C scaled to paper width
rise: 50 mV/°C
lowest temperature value: 197 °C
highest temperature value: 202 °C
Fig. shows 5 C scaled to paper width
rise: 2000 mV/°C
