Promotional electronic angular travel SKJ-210, SKJ-210CX, SKJ-210M actuators KJ-210 type rotary electric actuator is a kind of self-control regulation system, which is the power to 220V AC power directly to the self-control to accept conditioning system issued 4 ~ 20mA, 0 ~ 10mA or 1 ~ 5V DC, 0 ~ 10V DC analog signal to drive the control valve for precise positioning valve position, the valve position is displayed as a percentage of the requirements of the opening and the actual opening, and the valve position the actual opening in the same analog signal back to the automation control system. Is increasingly widespread application of an intelligent electric actuators. It can be widely used in power generation, metallurgy, petroleum, chemical, urban water supply, intelligent building, light industry and other industrial process automation systems. Features 1 accepts the automatic control to regulate the system sends the 4 ~ 20mA, 0 ~ 10mA or 1 ~ 5VDC, 0 ~ 10V DC analog signal, and manual servo amplifier built-in automatic adjuster without reprovision servo amplifier. 2, upper and lower limit actuator stroke, zero, span can be set on the actuator operation panel. 3, CNC operator panel with a 6 LED digital display, high-definition. Runtime can be displayed simultaneously input valve opening and the actual opening, to facilitate on-site monitoring. 4, the control precision ≤1%, deadband is adjustable from 0.5 to 10%. 5, the control process with an interrupt signal from the lock, setting positioning. 6, with a self-diagnostic function, the control panel can suggest failure Troubleshooting. 7, the machine has a control input signal error (including: interruption, dropped) automatic processing function, the user can pre-set system requires the opening and closing of the valve. 8, the servo motor with a variety of protection features. 9, communication output port can be RS485, pulse width modulation, analog and other. Please describe the output, the "Agreement" species when ordering.
