UPT – Ultra Low Power Timer

UPT – Ultra Low Power Timer

Features:

  • Ultra-low power consumption 0.4mA @ 24VDC
  • Ideal for remote applications running of battery power
  • Obtain up to 12 months run time of 12AH battery
  • Din Rail Mount alongside TT-MA Analysers
  • 12AH, 24V Lead Acid Battery System (optional)
    • Unlimited supply capacity options
The special ultralow-power timer (UPT) allows for a portable and affordable pair of rechargeable 12V sealed lead acid (SLA or AGM) 12AH rated batteries to run for over 3 months in a typical single channel measurement and data logging setup. Higher rated battery configurations will afford much longer periods.battery-1 The main features of the UPT are a user configurable “On” time and “Off” time with an extremely low power consumption of 0.4mA @ 24VDC. This is 10 to 20 times lower than most commercially available pull timers. The wide range of programmable “On” times from 30 seconds to 300 seconds (5 minutes) and “Off” times from 4 minutes to 120 minutes allow for a very wide range of desired intermittent sampling frequencies to be supported by the UPT module. The TT-MA(D) transmitter equipped with a TT-MA-DAT field MODBUS data logger module can be powered on & off at will for seamless recording of data with intermittent power operation. The boot time for TT-MA(D) modules is only one second allowing for a near instantaneous power up and power down minimizing power consumption for this type of intermittent use. There is a 15 second programmable delay from boot on the TT-MA-MODUS datalogger to ignore any non-representative pH and temperature values while the time averaging scheme come to the final equilibrium value. The default time averaging period is 10 seconds but is changeable upon request. In addition, for the duration of time that the units are energized the power consumption for each TT-MA(D) module is only slightly greater than 1 watt. This is extremely low power consumption for a field transmitter interfacing a heavy-duty industrial grade sensor. In contrast other transmitters capable of interfacing industrial grade sensors typically have power consumptions of 12 watts or more and with a boot time of anywhere between 10 to 60 seconds both of which make them unsuitable for this type of intermittent remote battery powered use.
