T25 is the first timer world-wide. This t25 has following features: 24265v ac/dc supply, 0.1 second to 990 hours timing ranges, multimode operation with led display and 0.01% accuracy. This microprocessor-based product incorporates all these features in an elegant 25 x 80 x 85 mm din rail enclosure. T25 has one and two-relay versions with a contact rating of 5 a/230v ac. Various functional features of the standard t25 model are on delay, interval, cyclic with on and off times independently programmable. There are some other types of digital timer such as: forward/reverse [forward/pause/reverse/pausetimes independently programmable], star-delta [star/pause/delta programmable], 9-step timer, auxiliary contact and delayed pulse. T25 replaces several hundred different order code types from other manufacturers, thus simplifying/minimising inventory.
