For monitoring, alarm handling, and storage of levels
DOL 61 is a Display and Alarm Unit for monitoring, alarm handling, and storage of levels from analogue input: 0-10VDC or 0-20mADC.
DOL 61 Display and Alarm Unit can be used with all sensors with 24VDC supply voltage and 0-10VDC or 0-20mADC outputs.
DOL 61 features a relay, that can be programmed to activate when a specific input criterion is met. For example, the relay can be used to sound a horn or flash a lamp when the ammonia level in a house exceeds 50ppm.
The Display and Alarm Unit stores data for up to 300 days on a mini SD-card, which is included. Data is continuously deleted and is stored with one decimal every 30 seconds.
DOL 61 can power a sensor with 24VDC.
The unit can operate in temperatures between 0 oC and +45 oC, with humidity levels between 10% and 90% RH and air pressure between 700 hPa and 1300 hPa.
DOL 61 is IP56 protected.
