I haven’t seen the manual; what do all these terminals mean? Please let me know, expert
The instruction manuals for Shenzhen Te’an’s gas alarm detectors are available on the official website
I clearly saw the stainless steel nameplate, which should have a part number on it; it’s usually possible to tell what type of instrument it is. It seems like the poster is trying to show off – -;P
It’s obviously a combustible gas alarm
V+ and V- are connected to a 24V DC power supply, while C and S are connected to the 4–20mA output. K1, K2, and K3 provide dry contact outputs, whereas J1, J2, and J3 offer active contact outputs. This is an inference based on the diagram regarding the terminals of gas detectors for flammable or toxic gases; the exact details must be confirmed by referring to the manual.
