AI-702M/704M/706M HIGH PERFORMANCE INTELLIGENT
(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.

Page 6: Terminal Layout And Wiring
To apply two-wire method, the J2 module should be installed and the resistance of every wire should be less than 2ohm. AI-702M/704M/706M can measure the lead wire resistance of two-wire method and save it to parameter “Sc”. However, the lead wire resistance changes as the temperature changes. - Page 7 FRONT PANEL AND OPERATIONS Upper display window ○ ① Lower display window ○ Set key ○ Data shift key (also for switching between ○ manual/auto cyclic display) Data decrease key (also for switch to ○ ② display the previous channel) ○...

Page 9: Parameter Description
PARAMETER DESCRIPTION * X means channel number. It can be 1~2, 1~4, 1~6 for AI-702M, 704M and 706M. Parameter Name Remarks Setting range x channel high alarm on when PVx (the present value of x channel)>H.ALx; H.ALx High limit alarm Alarm releases when PVx<H.AL - dFx. - Page 10 dIPx is set to select display resolution for channel x for linear inputs, the corresponding display resolution of dIP=0,1,2,3 are 0, 0.0, 0.00 and 0.000 Decimal point dIPx for thermocouple or RTD inputs, when dIP=0, the display position resolution is 1℃; when dIP=1, the resolution is 0.1℃. Note: dIP only affects the display, and has no effect on internal data.
- Page 11 E=0, Normal; E=1, Set M2(MIO) and M3(OUPT) support one channel input only. For example, to set a AI-702M with 2 inputs, slowly cyclic display, channel 1 input from three-wire RTD (J0 module on M1 socket), channel 2 input from thermocouple (J1...

If L5 dual real installed, set nonc=0, all in NO status, set nonc=127, all in NC status. NO/NC nonc However, by parameter “nonc”, the NO output can be 0 ~63, 127 selection...
- Page 13 When configuration of the instrument is completed, most parameters will not need to be set by field operators. Furthermore, field operators may not understand many parameters, and may probably set parameters incorrectly by mistake and make the instrument unable to work.
