FUNCTIONS AND FEATURES
● Programmable modular multiple inputs, thermocouple, RTD, voltage, current, and two-wire transmitter optional with 0.2%FS measuring accuracy. Every channel supports different input specification and freely defined measuring range, decimal position, resolution ratio, digital filtering strength and 0ther parameters.
● Using high performance component greatly reduces temperature drift and the mutual interference among channels,realizing same accuracy and anti-interference ability as single channel indicator.
● AI-702M, AI-704M/AI-704M2 and AI-706M multi-channel indicators provide 1~2, 1~4, 1~6 channels of measuring, and support internal calculation functions including square root extraction, summation, subtraction and multiplication.
● Support RS485 communication using as lower machine of AIDCS intelligent distributed control system, paperless data logger and touch screen control system. Provide switch signal inputs or outputs to upper machine.
● Up to 2 channels retransmission output when RS485 communication no need. Any input channel can be retransmitted by OUTP port or 6 channels can be cyclically retransmitted. Can be edited as 2 IN and 2 OUT transmitter.
● Equipped fixed point/patrol measurement display function and 2 patrol speed selectable.
● Supports E5 DIN rail mounted panel, can be edited directly by handheld display E8.
