The members of this product family are really multitalented, feature up to three presets and can be connected up using plug-and-play connectors. They allow very high counting frequencies of up to 60 kilohertz and are universally suitable for use as pulse-counters, tachometers, timers, shift or batch counters. The large multi-coloured 6-digit display is backlit and easy to read. The flexibility of the programming levels offered by this multifunctional counter allows it to be used as a position displays and, if required, with many programmable functions. Additional functionality offered by the RS232 interface facilitates quick, easy programming on the PC and enables the devices to communicate with a computer.
