data sheet pfa the fc series self-balancing recorder is capable of continuously recording up to three types of inputs like process signal, dc voltage, current, thermocouple signal, resistance bulb signal, etc. alarm units for the individual pens, external chart speed selector convenient for plant instrumentation, marking pen and many other optional accessories are prepared inside the self-balancing recorder. it is also usable as a trend recorder for 18 input points when combined with input selector (type: pfc). features 1. compact design measuring 96 mm wide by 144 mm high (front panel) by 400 mm deep (casing). 2. the recorder uses a folding type chart, of which one stack allows continuous recording for a month at a standard chart speed of 20 mm/h. 3. data are indicated in bargraphs with color ribbon. 4. the servo-mechanism consists of a contactless induction potentiometer and a powerful coreless-motor, thereby assuring high reliability. 5. chart speed is set accurately and can be switched easily by a combination of a clock circuit comprising a crystal oscillator and a pulse-motor. 6. the recorder can operate within a wide dc voltage range of 20 to 30v, or commonly at 50 and 60 hz with an ac power supply. 7. the recording pen is a cartridge type felt-tip pen requiring a minimum of maintenance. specifications input signal: process signal; 1 to 5v dc, 4 to 20ma dc dc voltage; 4mv span or more (30v max.) dc current; 100 a span or more (200ma max.) thermocouple; 4mv span or more (cold junction com- pensation, linearizer and burnout circuit built in.) resistance bulb; pt100 50 c span or more, 3- wire system (linearizer built in) jpt100 in accordance with jis c 1604-1981, 50 c span or more, 3- wire system (linearizer built in) slide rheostat; 10?00?0 ? , 3-wire system input resistance and allowable signal source resistance: see page 3 allowance: 0.5% of input span or 40 v, which- ever is larger dead band: 0.2% of input span or 16 v, whichever is larger response time: approx. 5 sec (variable within a range of approx. 2 to 20 sec) number of recording points: 1, 2 or 3 pens recording pens: cartridge type felt-tip pen pen no. 1 ... red, pen no. 2 ... green, pen no. 3 ... blue scale length: 100mm (recording width) chart length: 15m (continuous recording for 31 days at 20mm/h) chart feed system: pulse-motor type (driving pulse genera- tor circuit built in) chart storage system: folding system chart speed: 20mm/h basic (10, 30, 40, 60 and 120mm/h also selectable) chart speed accuracy: 0.1% as measured on time axis on the chart fc series self-balancing recorder date EDS10-15F aug. 31, 1994
