6 Digit LED Preset Add/Subtr. Counter, Timer, Frequency Meter CTF16/17 Features • 6-Digit Preset Counter with Sign & Scale Factor • Available with One or Two Presets • Programmable as a Pulse Counter, Frequency Meter or an Operating Time Counter • Wide-Range Power Supply 90-250 VAC • Counting Speed up to 20 kHz • Extremely Simple Use and Programming by Means of Only 4 Keys • RS-232, RS-422 or RS-485 Serial Interface Applications: Preset batch counting, length measuring, simple positioning, time control, speed control, rate control. Description: The CTF16/17 is a LED preset counter, timer or frequency meter. The following features are programmable: - Operating mode (counter, timer or ratemeter) - Polarity of the inputs (NPN or PNP) - Scale factor - Output signals continuous or pulse signal - Frequency meter display mode : 1/s or 1/min - Resolution in s, min, h or h:min:s - Start and Stop for the time counter/hours meter Inputs 2 counting inputs The maximum frequency is 20 kHz (12 kHz for Quad Input); 30 Hz debounce setting for contact closure inputs. GATE Inhibits count, controls timer RESET Edge triggered, Resets the counter to zero when counting up, and sets it to the preselected value when counting down. (Same as front reset button) KEY The keys are locked as long as this input is ON. The P preselection display key remains active. Outputs 1 or 2 potential-free relay or optocoupler outputs as ordered. Programming The CTF16/17 are programmed by means of the 4 front keys. The display prompts simple and intuitive programming. Programmable are: Input polarity Positive (PNP) or negative (NPN). The selection is valid for all inputs. Pulse or time counting modes - Adding with counting start at 0 - Subtracting with set to preset (CTF16) (preset 2 for CTF17) - Adding with automatic reset - Subtracting with automatic set to preset (preset 2 for CTF17) Input types in pulse counter mode Cnt. Dir 1 counting input; 1 counting direction input uP. Dn 1 adding input; 1 subtracting input quad Phase discriminator to connect pulse sources with 2 signals shifted by 90° quad2 Phase discriminator with double pulse processing, to connect pulse sources with 2 signals shifted by 90° Decimal places Select one, two or three decimal places. Scale factor Multiplying scale factor between 0,0001 and 99,9999. Output signal Each output can be selected as an opening signal, a closing signal or as a positive or negative pulse signal. Time counter Select time base of h, min, s or h:min:s. Set the resolution by selecting up to 3 decimal places. Frequency meter/Tachometer/Speed indicator Display in 1/min or 1/s with automatic conversion. Interfaces The devices can be fitted with the optional RS 232, RS 422 or RS 485 interfaces. These interfaces can be used to program the devices as well as for remote reading. They are simply controlled by ESC sequences. Explosion Proof Housing Option • All functions corresponding to type 717 with relay output • Sturdy, hard-coated aluminium housing with insert moulded connection cables (2 x 3 m) • Protection type: EEx d IIC T6 • PTB approval no.: Ex-96.
