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.
★
Each channel can have independent input specification. All channels are equipped with
digital adjustment and filtering functions and each channel have individual digital
adjustment and filtering parameters.
★
Customized channel number for easy reading when measuring more than 6 channels,
e.g. instrument 1 shows CH1 ~ CH6 while instrument 2 shows CH7 ~ CH12.
★
High performance hardware design, greatly reduce 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.
★
Build-in accurate internal calculation functions including square root extraction,
summation, subtraction 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.
★
Each input channel has independent low/high limit alarm which can be assigned to 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 via the indicator.
★
Up to12 customized field parameters.
★
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.
