AI-702M/704M/706M HIGH PERFORMANCE INTELLIGENT
MULTI-CHANNEL INDICATORS
Operation Instruction Version 7.6
(Ideal for measurement, indication, alarm, calculation and retransmission of
temperature, pressure, flow, level, humidity etc.)
SUMMARY:
AI-702M, AI-704M and AI-706M multi-channel indicators provide 1-2, 1-4, 1-6 channels of
independent process indications, and are ideal for the measurement, indication, alarm,
calculation and retransmission of temperature, pressure, flow, level and humidity etc.
Features:
★ Programmable and modular inputs. Multiple input types of thermocouples and RTDs,
voltage/current inputs and two-wire transmitters are field- selectable.
★ Every channel can have independent input specification. All channels are equipped
with digital adjustment and digital filtering functions and each channel can set different
digital adjustment and filtering parameters.
★ High performance hardware design, greatly decreased the temperature drift and the
interference between channels, thus multi-channel measurement accuracy is 0.2% full
scale, the same as that of single channel.
★ Provide high accuracy compensation function such as ice-point compensation, copper
resistance compensation and thermostat compensation to thermocouple inputs.
★ Provide accurate internal calculation functions including addition, extraction, and
multiplication.
★ Support up to 2 isolated retransmission output. Any input channel can be retransmitted
to OUTP port or all channels are cyclically retransmitted.
★ Provide manual/auto pilot display, with 2 pilot speed selectable.
★ Support up to 7 on-off signal inputs/outputs which can work as alarm output or on-off
signal I/O for host computer.
★ Every input channel has independent low/high limit alarm which can be assigned any
alarm output.
★ Advanced communication function. Provide high accuracy and stability multi-channel
analog data sampling function to host computer. The host computer can also input up
to 7 channel on-off signal or execute on-off operation through an indicator.
★ Allow to define up to 12 field parameters, and user can freely customize the instrument.
★ Multiple dimensions are selectable. 100~240VAC universal power supply.
★ Achieved ISO9001 and CE certificates, comply with EMC standard, high reliability and
stability. The power and I/O terminals have passed the anti-interference test of
4KV/5KHz burst of pulses.
