Al-7011/7021 is an intelligent, programmable temperature transmitter/signal
isolator designed for DIN rail mounting. It supports programmable input signals from
thermocouples, resistance temperature detectors (RTDs), linear voltage (mV), and current signals. The output is in standard current (4~20mA or 0~20mA), with the
input featuring digital filtering capabilities. The Al-7021 can operate as two independent
transmitters or signal isolators, reducing costs and equipment installation volume and
offering flexibility and convenience. The instrument supports a selectable power supply
of 24VDC/AC or 100-240VAC and has passed IS09001 quality certification, ensuring
high reliability and compliance with EMC electromagnetic compatibility standards. The
power supply and all I/O terminals have passed the 4KV Electrical Fast Transient (EFT) antiinterference test, enabling reliable operation in high-interference environments.
