Temperature controller

Main 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.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.  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 to 12 customized field parameters.

Model Code Legend

Designed with modular principle, AI-704M can be equipped with 6 modules on 6 sockets: M1, M2(MIO), M3(OUTP), ALM, AUX, and COMM. M1, M2 and M3 can be equipped with various input modules, each of which has 1or 2 analog input channels. ALM, AUX and M3(OUTP) can be equipped with relay output module, each of which has 1 or 2 alarm output channels. If necessary, M2 can also be installed with a single relay output module and work as alarm output. COMM can only be equipped with RS485 interface for communication with computer. M2 and M3 can be equipped with either analog input module for measurement or relay output modules for alarm. All inputs and outputs are programmable.

The ordering code of 702M is made up of 9 parts, for example:
