What the safety barrier instructions mean
Thread Content
Could you please explain what these two sentences mean in the instructions for the safety barrier? Thank you: Two-channel safety barriers, safety barrier potential:+/ evaluation barrier potential:+
English can be translated literally, but it’s not clear what it means. Safety barrier positive+/Evaluate safety barrier positive + – how should this be understood?
Are there really terms like positive-side safety and negative-side safety for safety barriers?
Dual-channel safety barrier: Compare the instructions for the safety barrier with the actual device; the terminal it is connected to is likely the positive voltage (power supply) terminal of the safety barrier, the + terminal
This seems to be talking about the polarity of the safety barrier, but I don’t understand what the polarity of a safety barrier means
This indicates the positive polarity of the safety barrier, but the evaluation barrier potential:+ – I don’t know what that means.
