Overview
The DFD-2100 electric servo operator from Shanghai Instrument Eleventh Factory is a DDZ-S series operating unit instrument. The instrument will switch between the control signals set remotely and automatically from DCS and the manually set control signals of this instrument according to the settings. After amplitude limiting processing, the signals will be sent to the servo amplifier, which directly drives the on-site actuator.
Product Details
The DFD-2100 electric servo operator from Shanghai Instrument Eleventh Factory is a DDZ-S series operating unit instrument. The instrument will switch between the control signals set remotely and automatically from DCS and the manually set control signals of this instrument according to the settings. After amplitude limiting processing, the signals will be sent to the servo amplifier, which directly drives the on-site actuator.
This operator can achieve undisturbed switching between manual and automatic modes, and accept remote switching contact signals to achieve remote manual/automatic switching.
This operator uses a dual pointer indication method to indicate the set value and output value.
