General features: scale: degrees Celsius Ambient temperature: 0 … 50 °C
DA450000
I
Output signal: consistently 0…10 V or 10…0 V (can be switched using a jumper), max. 5 mA Sensor: NTC internal Control function: Heating or cooling with adjustable p-band, aligned to 5 V at setpoint temperature Control range: 5 … 30 °C Hysteresis: 0 K, since control is always via the p-band in the
range from +0.5 K … 3 K (adjustable) Pipe system compatibility: 2-pipe
KTRVB-048.200
General features: Relative scale Ambient temperature: 0 … 50 °C Output signal: consistently 0… 10 V or +10… 0 V (can be switched using a jumper), max. 5 mA Sensor: NTC, internal Control function: Heating or cooling with adjustable p-band, aligned to 5 V at setpoint temperature Control range: 13 … 29 °C Setting range: −3 … +3 K (the pre-set “zero point” of approx. 21 °C can be adjusted in the machine by +/− 5 K) Hysteresis: 0 K, since control is always via the p-band in the
