AI-7048 High Performance Intelligent 2 Channel PID controller

AI-7048 High Performance Intelligent 2 Channel PID controller 1.4-channel PID 2.Multiple Installation 3.SSR OUTPUT

AI-7048 High Performance Intelligent 2 Channel PID controllerIt is capable of measuring and controlling four channels of temperature, and every channelcan define its own input specification. It can either work independently or cooperate with computer or PLC (Programmable Logic Controller).

Main Features

Providing up to four channels of configurable inputs, and supporting multiple thermocouple inputs with auto reference junction compensation and linear voltage (mV) inputs with user defined scale. Every channel has its own digital filtering and can adjust its filtering degree.High performance hardware design, which greatly decreased temperature drift and the interference among the four channels. Therefore, this multi-channel instrument obtains the same measurement accuracy and anti-interference ability as that of single channel instrument.Every channel has independent high/low alarms, and the alarms can be allocated to different alarm outputs or to the same alarm output (Just available for Dimension E5).Friendly and customized operating interface leads to easy learning and simple manipulation. Up to 12 parameters can be promoted to immediate operator access in Field Parameter Table.Advanced communication functions, compatible with the communication protocol of other AI series instruments. One AI-7048 communicates with the host computer the same as four independent controllers.Universal power supply of 100-240VAC or 24VDC.New generation D5/E5 rail mounted dimension. The width of D5 is only 22.5mm. The instrument can be easily configured by connecting to handset display.ISO9001 and CE certified and satisfied with EMC standard, achieving world class level of quality, anti-interference ability and safety. The power and all I/O terminals passed 4KV/5KHz EFT test, and the instrument can work stably under interference.
