GENERAL:

These devices shall comply with ordinary locations File E501171-D1000,

issued date 2018-09-25, Measuring, Testing and Signal-generation Equipment,

covering for this manufacturer and with the following description. Should the

Procedure File E501171-D1000, issued date 2018-09-25 be withdrawn, labeling

under this Procedure must be discontinued until authorization to resume is

received. In the case of any discrepancy between this File and File E501171-

D1000, issued date 2018-09-25, this file has precedence. When used in

hazardous environments corresponding to Class I, Division 2, the device must

be installed in an ultimate enclosure where the internal compartment is only

accessible by use of a tool.

These devices are considered Open-Type Analogue Signal Converter, which

can connect with 2- or 3- wire transmitter or current source signal. The input

and output circuits and the voltage supply are completely electrically

isolated. The input signal is converted into a DC current or voltage value.

The signal 0/4 -20mA is isolated and transferred through output side. The

product should be supplied by 20-30VDC power independently and they are three

ports isolation between power supply. Input and output.
