GENERAL DESCRIPTION

The signal generated by the two-wire or three-wire RTDs in

the application field is picked up by this product, and converted to

the standard analog current or voltage signal which is isolated

with application field, and transmitted to the control cabinet. The

product is armed with RS485 digital bus interface, which makes

network configuration and the input or output configuration

possible in PLC/DCS system. It is an intelligent product.

One independent power supply is required. Moreover, within

the product power supply, input and output are mutually isolated.

And have temperature over limit alarm and Off-line alarm

Field devices connected with this product:

Two-wire, three-wire RTDs (not to be used in intrinsically

safe area);

Note:

1.The initial setting of the product is signal type:Pt100, measurement range: -200~+800℃,, minimum range: 50℃, current output: 4~20mA. Customers can choose signal

type and range, or program with the programming software. (Which can be downloaded at www.mornsun.cn ).Modifying is also acceptable if there are special

requirements.

2. You can get the USB Adapter T-01 for the isolator from MORNSUN free of charge if you need.
