WEST控制(zhi)器分組(zu)合邏(luo)(luo)輯控制(zhi)器和(he)微程序(xu)控制(zhi)器,兩種(zhong)控制(zhi)器各有長處和(he)短處。WEST微程序(xu)控制(zhi)器設計方(fang)便,結構(gou)簡單,修(xiu)改(gai)或擴充都方(fang)便,修(xiu)改(gai)一條機器指(zhi)令(ling)的功(gong)(gong)能,只需重編所對應的微程序(xu);要增加(jia)一條機器指(zhi)令(ling),只需在WEST控制(zhi)存(cun)儲器中增加(jia)一段(duan)微程序(xu)。WEST組(zu)合邏(luo)(luo)輯控制(zhi)器又稱硬布線控制(zhi)器,由邏(luo)(luo)輯電(dian)路構(gou)成,完全靠硬件來(lai)實現指(zhi)令(ling)的功(gong)(gong)能。 Process controller WEST 6170+/8170+/4170 Remote Setpoint Option Modbus Communications Transmitter Power Supply Open Loop Valve Control with or without Position Indication Jumperless Configuration Improved 'Plus Series' Interface Available in 1/16 DIN, 1/8 DIN and 1/4DIN Formats Programmable digital process controller CAL 9500P West Control Solutions Full PID auto-tuning process controller Total of 3 outputs, from 4-20mA, 0-5v, 0-10v, SSR drive, relay Input options: Thermocouple 2 or 3 wire PT100 0-50mV, 0-5V, 0-10V, 0-20mA, 4-20mA Alarms with 5 options Heat-cool operation Programmer operation Sleeve mounting for easy maintenance IP66 protection from front panel CE, UL & CSA approvals
