New mini-D timers capable of operating from any AC or DC voltage down to 12V are able to run from any mains supply or battery backup in industrial or domestic applications worldwide.
New mini-D timers capable of operating from any AC or DC voltage down to 12V are able to run from any mains supply or battery backup in industrial or domestic applications worldwide.
The new Carlo Gavazzi DMB51CW24 DIN-rail timers are 17.5mm wide to enable space-saving installation, with multiple timing modes to support virtually any process control requirement.
By adding the DMB51CW24 to its existing DMB51CM24 timers for 24V DC and 24-240V AC power supplies, Carlo Gavazzi claims the widest range of mini-D timers on the market.
Mode and time duration settings are easily controlled using front-mounted knobs.
The available timer modes are delay-on-operate, interval, interval-on-trigger open, double-interval, delay-on-release, symmetrical recycler on-first, and symmetrical recycler off-first.
Two further knobs control time settings, from 0.1s to 100h.
Front-panel LEDs indicate power supply and relay status, with a flashing display while timing.
Accurate timing is achieved through precision time setting to within 5%, and less than 0.05% per volt timing variation within the rated power supply.
Timing variation with temperature is also very low, at less than 0.2%/C.
Carlo Gavazzi DMB51-series timers have 8A SPDT relay outputs, and can be configured for automatic or manual start.
All are mounted in the compact 17.5mm-wide DIN-rail package, with convenient front panel controls and status LEDs.
All DMB51-series members also pass EN60529 for environmental robustness, including IP20 ingress protection and IEC60664 level 2 pollution immunity.
The operating temperature range for all series members is -20 to +60C, and relative humidity to 95%.
This range also complements the Carlo Gavazzi range of single function timers, including the DAA51 delay on operate, DBA52 delay on release, DBB51 true delay on release, DAC51 start-delta, and DCB51 symmetrical recycler.
A PC programmable timer, DHA51, also supports custom applications or special functions.
All timers in the series carry CE, UL and CSA approvals, and meet the EMC standards EN61000-6-2 for immunity and EN50081-1 for emissions.
