AI-7021D5 2-Chanel pt100 temperature transmitter manufacturer
AI-7021D5 dual channel pt100 temperature transmitter manufacturer
___________________________________________________________________________
I. Main Features:
AI-7021 provides two-channel transmitters or signal isolators. It has the following features:
- It provides 2 channels of configurable inputs, and supports multiple voltage, RTD, thermocouple inputs with auto reference junction compensation. If parallel connected to an external precise resistance, it accepts current signal input. Each channel has its own digital filtering and can adjust its filtering degree.
- It generates two isolated current outputs, 4-20mA or 0 – 20mA. The range of retransmission output can be freely defined.
- This model uses high performance hardware, which leads to greatly decreased temperature drift and interference among the two channels. As a result, this multi-channel instrument achieves the same measurement accuracy and anti interference ability as that of single channel instrument.
- It generates digital adjusted current output without potentiometer, making the current output precise and stable.
- The model is DIN rail mounted. Its width is only 22.5mm. The instrument can be easily configured by connecting to our E8 handset display.
- Universal power supply of 100-240VAC or 24VDC.
- ISO9001 and CE certified and meets EMC standards. Its power and all I/O terminals pass 4KV/5KHz EFT test and can work reliably under interference.

III. Front panel and Operation:
The parameters of AI-7021D5 can be set by an external E8 display which can be used to configure AI-7021D5 at the initial set up, as well as remain connected to AI-7021D5 and serves as an external display.
The functions of the parts of E8 external display panel is as below:
1. Upper display window, displays PV of channel 1 or parameter code, etc.
when display keep flashing or the reading abnormal, please check the input specification set correct or not.
2. Lower display window, displays PV of channel 2 or parameter value.
When display keep flashing or the reading abnormal, please check the input specification set correct or not.
3. Setup key, for accessing parameter table and conforming parameter modification.
4. Data shift key.
5. Data decrease key.
6. Data increase key.
