Analog and digital timers

22 July 2009 Switches, Relays & Keypads

Adding to its range of timer modules, Panasonic has introduced new analog and digital timer families.

The analog PM4H variants feature various operating modes including pulse ON-delay, pulse flicker, pulse ON-flicker, differential ON/OFF-delay, signal OFF-delay, pulse one-shot and pulse one-cycle modes. They have a time range stretching from 0,1 seconds to 500 hours, which is controllable by an easy-to-read analog setting. Operating voltages are 12 V d.c., 24 V a.c./d.c. and 100–240 V a.c., with a 250 V a.c. relay output capable of driving a 5 A load. They are protected to either IP50 or IP65 in front and feature exchangeable black and white panel covers. The timers are available with pin or screw terminal connections and measure 48 x 48 mm on the front panel, with installation depths of 62,5 or 66,5 mm, depending on the model.

The digital LT4H timers feature power ON-delay, signal ON-delay, signal OFF-delay, pulse one-shot, pulse ON-delay, signal flicker and totalising ON-delay operating modes, selectable via a DIP switch. They have a two-colour backlit LED display and a time range from 0,001 seconds to 999,9 hours. Operating voltages and relay output are identical to the analog versions, with an additional transistor output switching 100 mA at 30 V d.c. They are protected to IP66 in front and feature exchangeable black and white panel covers. The timers are available with pin or screw terminal connections and measure 48 x 48 mm on the front panel, with installation depths of 65,5 or 70 mm, depending on the model.
