DESCRIPTION

BDC34 is a sophisticated new-generation counter. The device is equipped with a 6-digit display, which can hold up to 999999 count units or batches, and may have up to 2 programmable relay outputs and an analog output for alarm signalling or process controlling. BDC34 is available as a counter, as an R.P.M. meter, and as a combination of both. As a counter, this model allows programming of 7 different counting and output relay- action modes (including dosing mode) as well as counting pulses or pulse batches. The R.P.M.-meter variant has 6 operating modes. Besides its counting input, the device has three additional inputs: CLEAR, GATE, and DIRECTION. A userprogrammable software input filter is also available. Other useful BDC34 features are the fraction number coefficient prescaler and the programmable actual and displayed counting directions. With its various features and flexible programmable internal structure, the BDC34 counter is a widely applicable industrial control device.
