CT34 is a sophisticated new-generation counter quipped 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 signaling or process controlling. СТ34 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, CT34 has 3 additional inputs – CLEAR, GATE, and DIRECTION – and a user-programmable software input filter. Other useful features include fraction number coefficient prescaler and programmable actual and displayed counting directions. With its various features and flexible programmable internal structure, the CT34 counter is a widely applicable device.

(1) Not available for case ‘L’
(2) Available ONLY for variant ‘CR’!
(3) Only with pulse input type!
(4) NO for case ‘L’
(5) Ask for availability!
(6) ONLY with isolated power supply!
(7) In case of variant ‘CR’ with pulse input, if not additionally specified, 1st relay is linked to counter and 2nd – to R.P.M. meter.
With analog input, 1st relay is firmly linked to counter and 2nd relay is user programmable.
(8) Instead of 2nd relay (_G5)!
