FUNCTIONS AND FEATURES
l The input can be freely selected as thermocouple, RTD, voltage, current, Ohm signal and etc.
l Support up to 4 channels alarm relay output including 2 channels high limit alarms and 2 channels low limit alarms.
l With functions of digit calibrating, digital filtering, and thermocouple cold junction auto compensating, it is free of maintenance and easy operated.
l Support high accuracy retransmission output with accuracy up to 14-bit D/A and temperature drift less than 100PPm/℃.
l Support RS485 communication interface, widely used for AIDCS, split paperless recorder and touch screen control system.

ATTENTION:
1. AI-751 supports Modbus RTU protocol and only A and E dimensions are available.
2. AI-500/700 doesn’t have light bar.
3. D size doesn’t have MIO, and its COMM and ALM share one slot. If indicators installs RS485 module, it doesn’t have ALM; If controller requires alarm function it can install alarm module in AUX.
4. D2 size doesn’t have MIO and ALM, and its COMM and AUX share one slot. So controller should choose either RS485 or alarm function. If require both RS485 and alarm, users should choose D6 size which supports module SL. D2 size doesn’t support 0~5V/ 1~5V linear current input. Users can transform the signal into 0~500mV/ 100~500mA or choose D6 size.
5. About MIO: it supports 4~20mA/ 0~20mA input or signals from 2-wire transmitter when installing I4 module. Yudian instruments support thermocouple and RTD input as standard configuration.
MODEL SELECTION
There are maximum five module slots: multi-function input (MIO), main output (OUPT), alarm (ALAM), auxiliary output (AUX) and communication (COMM). The modules can be purchased together or individual, and can be assembled freely.
Example 1:
AI-701E5I4X3L3L3S4
AI-701 E I4 X3 L3 L3 S4
① ② ③ ④ ⑤ ⑥
① Main model for instrument is AI-701, single channel indicator, with single display and measuring accuracy of 0.2%FS
② Front panel size is E 48*96mm.
③ I4 module in MIO means 4~20mA/ 0~20mA or signals from 2-wire transmitter input.
④ X3 module in OUTP means linear current 4-20mA retransmission output.
⑤ Both ALM and AUX are installed with L3 module which means 4 channels alarm relay output.
⑥ Communication module S4 is in COMM which means instrument supports RS485 communication with isolate power supply.
