This 12V DC timer is specially made for applications where rain and day light needs to be taken into account when deciding when a device should turn ON or OFF. You can have your normal programming schedule input but the timer will work based on rain or intensity of light.Let suppose there is a remote irrigation application where a timer turns ON and OFF a 12V DC pump at a certain schedule. If you have a raining day, the timer will not turn ON the pump as scheduled and there will be savings on water and battery charge, which on a raining day it is already compromised. On the next scheduled event the timer will go back to its normal schedule if it is not raining. If it is still raining, than the timer will also skip this event and will try on the next scheduled event.
This 7 day digital programmable timer is ideal for use in any 12V DC appliance which requires automation. It can be configured to switch at up to 16 different times during a 24 hour period. In addition, it can be programmed to operate on a wide variety of days. eg. Daily, Week days only, Weekends only, Every second day, or selected group of days.The BRX12A25LR allows for Switch-on and switch-off times to be set for each program. i.e. allows a different "on" duration for each program.The timer has three modes of operation. In the "auto" mode, the timer automatically switches at the pre-programmed times. In the "on" mode, the switch is always on regardless of the timer program setting. In the "off" mode, the timer will not switch regardless of the program settings. The mode of operation can only be changed when power is applied to the switch.In the event of a power failure, the switch retains its program data via backup battery- Voltage: 12V DC- Max Total Load: 25A (Resistive Load)- Standby consumption: <0.03A- Dimensions: 120mm x 72mm x 50mm- Weekly & Daily Programming.- Timing Control Range: From 1 minute to 168 Hours- Up to 16 events per day or 112 events per week. Example: You can set 1 "ON & OFF" event to repeat the 7 days of the week and you will be using only 1 out of the 16 events allowed.- 16 ON and 16 OFF events can be programmed independently.- Accuracy: <±2 seconds per day- Operating temperature: +10 ~+50 C- Relative Humidity: 95%- Guide Rail & Wall mounting & Panel- Battery backup- Manual override eliminates the need for an additional helm switch.- A 25A fuse is strongly recommended for each installation as it will assure a long life for the timer as it will avoid overload of the system.We ship worldwide. - Hablamos Español. - Nous parlons Français.
