Product Advantages

1.Analog input/output: Supports analog input and output, can process 4-20mA signals or DC 4-20mA signals, and isolate and transmit them to a safe area. The output signal is 4-20mA.

2.Input and output channels: one input and two outputs, which can flexibly meet different signal transmission needs.

3.Isolation function: To achieve electrical isolation between input and output, ensuring the stability and safety of signal transmission.

4.Power supply function: When the on-site transmitter is a two or three wire system, the safety barrier can provide power distribution for the transmitter to ensure its normal operation.

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

6.Support for Hart signal: Compatible with Hart signal, suitable for application scenarios that require support for the Hart communication protocol.

* Bus power supply, see appendix for details.
