Isolated safety barrier 1

The thermocouple signal from the dangerous area is transmitted to the safe area through a single or isolated two-way current signal through isolation, and serial communication networking can also be performed in the safe area through the configured communication interface. 产品,用户可通过专用编程器对本产品进行输入信号类型及输出量程的设置。 It is an intelligent safety barrier product. Users can set the input signal type and output range of the product through a special programmer.
Explosion-proof sign
Ex (ia) ⅡC
Input / output accuracy
± 0.2% × F · S

Danger zone allows input signal thermocouple: K, E, S, B, J, T, R, N
The signal type and range are determined at the time of order and can also be programmed by yourself.
Output signal DC to safe area: 0-10mA, 4-20mA, 0-5V, 1-5V, 0-10V The signal type and range are determined at the time of ordering, and can also be programmed by yourself.
Communication (only in safe area)
RS232 or RS485 interface, please refer to the communication technology in this manual. When the communication function is selected, there is no second output function.

Power DC 24V

Power consumption
1.2W ~ 1.8W (depending on the model, see the calculation method of input power in the appendix of the product manual for details)

Dimensions width x height x depth: (22.5 x 100 x 115) mm

China National Instruments Explosion-proof Safety Supervision and Inspection Station Certification Parameters (between 9 and 10 terminals)
Uo = 8.7V, lo = 27mA, Co = 3.0μF, Lo = 20mH

Scope of application: thermocouples K, E, S, B, J, T, R, N
