Counter timers aimed at panel builders and OEMs
Switchtec
H7E counter timers
Switchtec has introduced H7E counter timers from Anly, offering users monitoring facilities in control panels and other equipment where lapsed time or events must be recorded.
The timers are aimed at panel builders, equipment manufacturers, H and V companies and OEMs.
The H7E is available as two variants to cover specific tasks: the H7E-C is an eight-digit totalising counter, while the H7E-T is a seven-digit timer counter.
The H7E-C has the option for standard (30Hz nominal) counting, and using a built-in DIP switch can be converted to high-speed 1kHz counting.
It can count up to 999,999,999.
The H7E-T hours run counter display can be switched between hours and minutes or hours, minutes and seconds, again via the built-in DIP switch.
It can count up to 9,999hr 59.9min or 999hr 59min 59sec.
Both units are powered from an internal 3V DC battery.
For the H7E-C, the battery has a life of seven years, extending to 10 years for the H7E-T.
The battery is said to be easy to change, and a pull-out tab ensures the battery is not being drained during pre-fitment storage.
An optional 24VAC/DC can be supplied to the timers if a backlight facility is required in a poorly lit application.
Both versions of the H7E counters feature a compact design measuring 47.9 x 34 x 54.5mm and mount into a panel cut out of 44.7 x 22.2mm.
Both versions also have built-in reset facilities.
This reset can be effected either at the front of the panel or remotely using the terminals at the back of the counter.
The front reset can be disabled using the selector switch on the counter, preventing false resets.
When mounted in a panel, a rubber sealing gasket ensures that an IP65 degree of protection is achieved.
A maximum relative operating humidity of 85 per cent is specified for the timers.
