Product Description

 

Product Name	Isolated Safety Barriers
Application	Electric Power Transmission
Place of Origin	China
Quality	High-quality
Feature	Long Life

 

1.Analog input/output: Supports two analog inputs and two analog outputs, can process 4-20mA signals, and achieve signal transmission from safety zone to danger zone.

2.Actuator drive: can drive on-site valve positioners, electric/pneumatic converters, and other actuators to operate and control the control system.

3.Signal transmission: Realize the transmission of 4-20mA signals from the safety zone to the danger zone, ensuring the stability and reliability of signal transmission.

4.External power supply: An external 20-35VDC power supply is required to provide sufficient power support.

5.Power input output isolation: The power supply, input, and output terminals are isolated to ensure electrical isolation between each port and enhance system stability and safety.

6.Bus terminal power supply: By supplying power through bus terminals, a convenient power supply method can be achieved. For detailed information, please refer to the appendix.
