4-DIGIT RATE INDICATOR - RC1 - SELECTRON MODEL RC100 IS A 4-DIGIT RATE INDICATOR ACCOMODATED IN A DIN ENCLOSURE OF SIZE 48 MM (H) X 96 MM (W). THE 0.5", BRIGHT RED LED DISPLAY REVEALS THE RATE OF INPUT PULSES IN RPMS. IT CHOOSES THE RESOLUTION OF THE DISPLAYED VALUE ON ITS OWN BETWEEN 4.000 AND 9999. THIS AUTO RANGING ADVANTAGE MAKES IT AN EASY TO USE INSTRUMENT FOR A NUMBER OF RATE INDICATION APPLICATIONS. THE INSTRUMENT ALSO CHOOSES THE SUITABLE RESPONSE TIME FOR DISPLAY UPDATE, RELYING UPON THE INPUT PULSE FREQUENCY AND TUNES TO IT. IT THUS EXHIBITS AN ACCURATE (0.05%) AND STABLE READOUT EVEN FOR ERRATIC PULSES. IT EXHIBITS SWIFT AND DYNAMIC RESPONSE TO UNFORESEEN CHANGES IN THE SPEED. APPLICATION AREAS ARE SPEED MONITORING OF MOTORS, FLOW RATE INDICATION, AND PRODUCTION RATE MONITORING. IT TAKES IN INPUTS FROM SENSORS LIKE LIMIT SWITCHES, PROXIMITY SWITCHES, PHOTOELECTRIC SENSORS AND POTENTIAL-FREE CONTACTS. IT HAS A BUILT-IN 12 V DC SUPPLY FOR POWERING THE SENSORS THAT ARE PROTECTED AGAINST SHORT CIRCUITS. IN LOW SPEED APPLICATIONS, IT IS A COST EFFECTIVE SOLUTION, REPLACING USE OF ENCODER OR MULTITOOTH WHEELS. THE INSTRUMENT NEEDS A PANEL CUTOUT OF 45 MM (H) X 92 MM (W) AND A CLEAR SPACE OF 120 MM BEHIND THE PANEL. IT NEEDS A SUPPLY OF 230 V AC/110 V AC/24 V AC AT 50/60 HZ OR 12 V DC OR 24 V DC (FACTORY SET).

TOTALISER-CUM-RATE INDICATOR - MODEL RC1 - SELECTRON MODEL RC102 IS AN INTELLIGENT TOTALISER-CUM-RATE INDICATOR. IT SUITS ALL TOTALISING AND RATE INDICATING APPLICATIONS IN SYSTEMS THAT PROVIDE PULSE SIGNALS. APPLICATION AREAS INCLUDE TEXTILE, FLOW METERING, EXTRUSIONS, PIECE COUNTING AND SIMILAR TYPES OF PRODUCTION AND PROCESS MONITORING. THE UNIT HAS A PROGRAMMABLE SCALE FACTOR OVER A WIDE RANGE (0.00001 X 10-3 TO 9.99999 X 10-2). THIS FACILITATES THE READING OF RATE AND TOTALISER VALUE DIRECTLY IN DESIRED ENGINEERING UNITS. THE INSTRUMENT CAN BE SET TO DISPLAY EITHER 6-DIGIT TOTAL OR 4-DIGIT RATE VALUE. WHEN SELECTED TO DISPLAY TOTAL, IT SHOWS TOTAL NUMBER OF PULSES RECEIVED MULTIPLIED BY THE,SCALE FACTOR. THE LEAST COUNT OF THE DISPLAY CAN BE SELECTED BETWEEN 0.01, 0.1 OR 1 VIA DIP SWITCH AT THE REAR. IN RATE MODE, THE INSTRUMENT AUTOMATICALLY SELECTS THE DISPLAY RESOLUTION AND DISPLAYS INPUT PULSE RATE FROM 4.000 TO 9999 UNITS PER MINUTE. EXCELLENT STABILITY AND GOOD RESPONSE TIME ARE THE SPECIAL FEATURES OF THE RATE INDICATION. AS A SECURITY, THE SCALE FACTOR CAN BE LOCKED USING DIP SWITCH. THE TOTALISER VALUE AND SCALE FACTOR ARE RETAINED FOR 10 YEARS IN CASE OF POWER FAILURE. AN IN-BUILT 12 V DC (± 10%) SUPPLY IS PROVIDED FOR POWERING VARIOUS SENSORS SUCH AS PROXIMITY SWITCHES. THE INSTRUMENT HAS A SUPPLY OF 230 V AC/110 V AC/24 V AC OR 24 V DC OR 12 V DC (FACTORY SET) AS DESIRED, IS HOUSED IN DIN ENCLOSURE OF BEZEL SIZE 48 MM X 96 MM AND REQUIRES A PANEL CUTOUT OF 45 MM X 95 MM WITH 120 MM CLEAR SPACE BEHIND PANEL.

RATEMETER/TOTALISER - RC1 - SELECTRON'S RC104 IS A PULSE INPUT RATEMETER/TOTALISER WITH ANALOGUE OUTPUT (0-10 V DC/4-20 MA) USEFUL FOR DC DRIVE CONTROLS, FLOW MEASUREMENTS AND OTHER PROCESS APPLICATIONS. THE ANALOGUE OUTPUT CAN BE USED AS FEEDBACK TO DC DRIVES FOR MOTOR CONTROL OR FOR TRANSMITTING THE RATE INFORMATION IN CONTROL SYSTEMS. IT MONITORS THE RATE IN 5 DIGITS AND TOTAL IN 6 DIGITS. THE SCALE FACTOR (K) IS PROGRAMMABLE, ALLOWING THE DISPLAY TO BE CALIBRATED IN UNITS OF VOLUME, LENGTH, ETC. THE RC 104 ACCEPTS INPUT FROM SENSORS SUCH AS PROXIMITY, MAGNETIC PICKUPS, NAMUR SENSORS AND OTHERS. INPUT FREQUENCY ACCEPTED IS UP TO 10 KHZ. IT HAS AN IN-BUILT 12 V DC SUPPLY TO ENERGISE SENSORS. THE ANALOGUE RESPONSE DAMPING CAN BE PROGRAMMED ACCORDING TO REQUIRED ACCURACY VS RESPONSE TIMES FOR RELEVANT INPUT PULSE SPEEDS. THIS AND OTHER VERSATILE FEATURES MAKE THIS PRODUCT A USEFUL, COMPACT AND ECONOMIC SOLUTION IN APPLICATIONS WHERE MORE THAN ONE PRODUCT OR EXPENSIVE INSTRUMENTS ARE PRESENTLY USED TO REALISE THE REQUIRED FUNCTIONS. IT IS AN EFFECTIVE IMPORT SUBSTITUTE FOR SPECIALISED FREQUENCY TO CURRENT TRANSDUCERS AND RATE INDICATORS. IN COMBINATION WITH SELECTRON'S ENCODER, IT OFFERS A LONG LIFE ALTERNATIVE TO CONVENTIONAL ANALOGUE TACHOGENERATION SYSTEMS WITH/WITHOUT INDICATORS AT A FRACTION OF THE COST. THIS INDICATOR/TRANSMITTER IS A PANEL MOUNTING INSTRUMENT HAVING A FRONT BEZEL OF 48 (H) X 96 (W) MM WITH A DEPTH OF 120 MM. IT OPERATES ON MAINS AC VOLTAGE.

4-DIGIT PRESET COUNTER - XC2 - SELECTRON MODEL XC22A IS A 4-DIGIT PRESET COUNTER. THE PRESET VALUE COULD BE SET USING PUSH WHEEL SWITCHES FROM THE FRONT BEZEL. USER AREAS HAVE MANUFACTURING AND PROCESS APPLICATIONS IN ORDER TO HAVE A CONTROL OVER THE FOLLOWING: BATCH SIZE CUT TO LENGTH OPERATION, BATCHING, PACKING, ROLL FORMING, BLENDING, PUNCHING AND DRILLING, AND COUNT, LENGTH, POSITION APPLICATIONS. COUNT VALUE IS DISPLAYED AS A 4-DIGIT BRIGHT RED, 7-SEGMENT LED DISPLAY. THE DISPLAY INCREASES BY ONE ON EVERY PULSE AT THE INPUT. WHEN IN THE ON DELAY MODE, THE RELAY IS OFF WHILE THE COUNTING IS ON AND TURNS ON WHEN THE SET POINT IS REACHED. IN INTERVAL MODE, THE RELAY IS ON WHILE THE COUNTING IS ON AND TURNS OFF WHEN THE SET POINT IS ACHIEVED. IN AUTORESET MODE, THE WAITS FOR A SPECIFIC TIME DURATION COULD BE AFTER REACHING THE SET POINT. IT RESETS THEREAFTER, FOR THE START OF A NEW CYCLE. THE TIME DURATION IS FIELD SETTABLE THROUGH A POTENTIOMETER FROM FRONT PANEL. IN NON OVERRUN MODE, THE COUNTING CEASES AFTER THE SETPOINT IS REACHED, AND LATER CONTINUES. THE INSTRUMENT TAKES IN INPUTS FROM A VARIETY OF SENSORS LIKE LIMIT SWITCHES, PROXIMITY/PHOTOSWITCHES, ETC. THE PROXIMITY CAN BE NPN OR PNP TYPE. AN IN-BUILT 12 V DC SUPPLY IS PROVIDED FOR POWERING THE SENSORS. IN THE ABSENCE OF POWER, THE CURRENT COUNT VALUE IS RETAINED FOR 30 DAYS IN BATTERY BACKUP MODELS. THE XC22A IS HOUSED IN A 72 MM X 72 MM DIN ENCLOSURE. IT NEEDS A PANEL CUTOUT OF 68 MM X 68 MM AND A CLEAR SPACE OF 120 MM AT THE BACK OF THE PANEL. THE INSTRUMENT IS POWERED FROM 230 V AC, 110 V AC, 24 V AC OR 12 V DC OR 24 V DC SUPPLY (FACTORY SET) AND CAN BE SEEN IN 2-DIGIT OR 4-DIGIT MODELS.
