Microprocessor Pid Controller
Description: Microprocessor PID controllers are highly reliable and accurate digital controllers that are suitable for critical HVAC control requirements such as clean rooms, isolation rooms, laboratory, central plants, and utilities. The industry grade control performance provides versatile input selections and PID plus fuzzy functions. Features include multi range in output (TC, RTD, mV, mA), each 14 bit resolutions, fuzzy/PID control with two individual outputs, three sets of alarm each with 17 modes, implement zero/phase control by trig SCR module directly, E2-PROM non-volatile memory,RS232 and RS485 communication, self-diagnosis function, auto-zero and auto-span circuit keeping good accuracy, free range voltage AC85- 265 V/DC 15 -50 V, data lock function, auto/manual showing with 10 LED, 2 patterns each 8 segments programming procedure available to be ordered and input 2 used in remote SV. Specifications: power supply - AC 85 to 265 V 50/60 Hz; power consumption - about 4 VA; memory element - E2 PROM: display accuracy - within 0.2% of displayed value +1 digit; sampling time - 250 ms; input signal - thermocouple, RTD, DC, voltage/current; isolation - output part (control, alarm, transfer) and input part (measuring, CPU) are isolated separately; dielectricity - measuring terminal - grounded terminal AC 1000 V, 1 min; power supply terminal - grounded terminal AC 1500 V, I min; isolated resistance - measuring terminal - grounded terminal DC 500 V more than 10 ??; power supply terminal - grounded terminal DC 500 V > 10 ??; operating temperature 0-50°C; storage temperature - 25-65°C; humidity range - 50 85% RH (not dew); and net weight - FY400 approx 150 g, FY600/FY700/FY800 approx 225 g. and FY900 approx 300 g.
