The latest intelligent electric valve controller

Founded in 1993, Shenzhen Dongyi Electronics Co., Ltd. is a high-tech enterprise specialized in designing, developing, manufacturing and marketing industrial automation products. It is also one of the earliest manufacturers to develop and produce industrial automation measurement and control instruments in China. The company received a number of national patents instrumentation technology (patent number: ZL94212013.2 ZL95228872.9 ZL00133062.4), strong technical force, advanced production technology, testing equipment, excellent product performance, and actively implement the ISO9001 quality assurance system standards. After years of product upgrades, ZXQ series of products for high-performance digital instrumentation used in various industries can be used as a variety of intelligent regulators, DCS, PLC systems and inverter back-up manual operation. Complete the direct operation of various implementing agencies and the inverter and feedback tracking to achieve automatic manual / state of non-disturbance, for the system start-stop, fault handling to provide convenience. Widely used in electric power, steel, petrochemical and light industry and other industries. Typical applications in the standard current or potentiometer feedback supporting the use of electric actuators, intuitive display, easy to operate. The positioner can accept the DC 4-20mA adjustment signal from the upper instrument and the "three-wire" signal (or the valve position feedback signal of DC4-20mA) of the lower actuator actuator to output the "on" and "off" signals, To achieve the valve opening control and regulation. 1, the control accuracy: 0.1% -3.0% (adjustable); 2, can be connected to the electric actuator feedback signal: Potentiometer 500Ω-10KΩ; 3, can receive external control signal (DC): 4-20mA, other input signals from the factory 4) Can set the mode of "forward / reverse actuator" and "interrupt" mode when the input signal is interrupted-OPEN, STOP, SHUT 5. Can set whether electronic system 6, SCR output: AC, 600V, 25A; 7, the output actuator position signal: low drift output 4-20mADC corresponding actuator fully closed to fully open, the signal is completely isolated from the input (optical isolation); 8, Ambient temperature: 0-70 ℃ (can be set), humidity: ≤ 90% RH; 9, over-temperature protection; 10, Dimensions refer to the online description; 11, free calibration of the input signal by the button corresponding to the actuator 12, manual / automatic interference-free switching; 13, the actuator stall detection control; 14, can be set to allow changes in accuracy or re-adjust the time; 15 ,dense Lock, to prevent misuse; 16, intelligent pitch adjustment step input signal and a precise positioning actuator by angular positions; 17, with an error code indicating the cause of the malfunction; 18, RS485 communication function can be extended; 19, special requirements can be customized
