Preset Counter/Ratemeter APPLICATION: Counting/controlling cycles, parts, length, distance, flow, batching, position, feed rate, RPM, speed, etc. DESCRIPTION: The PS2 Programmable Electronic Counter & Ratemeter displays count rate or total in several operating modes. Two preset outputs can control rate, count, batching, positioning, length, distance, flow, etc. All three versions CR, CP & RP have presets and scaling. CR is a 6 digit counter and 5 digit floating decimal ratemeter. It has two 5 digit presets and independent scaling of inputs A and B. The counter is programmable for “net” A + B, A - B; or “SEP” A & B as separate counts in up or down count modes. Rate of input A can be scaled into engineering units and displayed per seconds, minutes or hours. Simply push the view button to display either rate or totals. The two output relays operate on count or rate presets in a latch to reset or auto cycle mode with programmable latch times (0.1 to 99 seconds). CP is a 6 digit, programmable, two preset, scaleable counter version. RP is a 5 digit, programmable, two preset, scaleable ratemeter version. SPECIFICATIONS: Display: 6 digit, 0.55" high LED Input Power: 110, 220 VAC ± 15% or 12 to 15 VDC Current: 250 mA DC max. or 6.5 VA AC Output Power: (AC powered units only) +12 VDC @ 50 mA, unregulated -10 + 50% Temperature: Operating: +32ºF (0ºC) to +130ºF (+54ºC) Storage: -40ºF (-40ºC) to +200ºF (93ºC) Humidity: 0-90% Non-condensing Memory: EEPROM stores data for 10 yrs. if power is lost. Inputs A & B: 1: Standard High Impedance DC pulse input. Open or 0-1 VDC (low), 4-30 VDC (high), 10k Ω imp. 10k Hz max. speed. Accepts simultaneous inputs. (For open collector (NPN) sinking inputs, use external pull up resistor 2.2k to 10k Ω.). Simple front panel programming of presets, scaling, rate/count modes, count speed, outputs, lockout code etc. Two 5-digit presets with 10 A relay or NPN transistor outputs Two simultaneous inputs with independent scaling Add, subtract or separate inputs in up or down count modes Quadrature and up /down direction control inputs NEMA 4X / IP65 front panel Compliant CSA approved, Optional RS232 or RS422 serial port Optional 4-20mA or 0-20mA analog output 2: Standard pulses on input A, Direction Control standard input B (When B is “high”, 4-30 VDC, the count inputs on A will count up and when B is “low” A counts down). 3: Magnetic pickup input. inputs A & B, accepts 30mV input (50 V max. P/P) signals 10k Ω imp. 5k Hz max. 4: Mag. input A, standard input B. 5: Mag. input A, Direction Control standard input B. 6: Quadrature, accepts standard pulses with 90º phase shift for direction detection. 7: Quadrature, accepts Mag. pulses with 90º phase shift for direction detection. Count speed: Programmable 10k Hz high speed or 40 Hz low speed with debounce filtering. Reset: Front Panel: displayed value and control output. Remote: 4-30 VDC negative edge resets count "A" and control output. Scaling Factor: The programmable 5 digit divider, with decimal, allows easy division from 0.0001 to 99999 for engineering units. Each input has independent scaling. Presets: A 5 digit value can be entered for both presets. The A and B outputs can be assigned to the ratemeter (high/low), one preset for rate and one for count, or two presets (2 stage shut off) on the A and B count. The outputs can be set to energize from 0.1 to 99.9 seconds with auto reset at preset or latch (0.0) until reset. Control Outputs: Two relays: N.O., 10 A 120/240 VAC or 28 VDC. (N.C. relay contacts and NPN transistor output available. Transistor, sinks 10 VDC to .5 V @ 100 mA) Analog Output: An optional 4-20mA (0-20mA) output is available. The output can be programmed to track rate or total. Programmable by using the front panel and rear dip switches. Accuracy: ±.25% FS worst case. Compliance Voltage: 3 to 30 VDC non inductive. Lockout: Prevents unauthorized program changes (5 digit code). The front panel can be completely locked out or presets and reset can remain accessible. Ratemeter: Accurate to 4 1/2 digits (±1 display digit). The rate display updates once per second with a programmable delay factor of 2 to 24 seconds before default to 0. Scaling permits rate display in almost any unit of measurement, and auto-range up to 5 digits of significant information. In the "RPS" mode, the ratemeter displays in units per sec-

Counter: The two 6-digit counters count at 10k Hz max. Each has a 5-digit dividing scale factor. The counter advances on the positive edge of each pulse. Up or down count modes are available, as are quadrature inputs from encoders for position or flow measurement. The unit can be programmed to view the net value of "A + B" or "A - B", or A and B as separate totalizers. RS232/RS422 Serial Interface: If the serial interface option is supplied, up to 99...
