II. Main Functions

High-precision acquisition: Suitable for continuous quantities such as pressure, flow, level, temperature, etc.

Breakdown detection: <3.8mA determines breakdown and triggers an alarm

Hot-swappable: Can be replaced online without affecting other modules

Self-diagnosis: Over-range, short circuit, module failure

Surge / ESD / reverse connection protection, suitable for harsh industrial environments

III. Typical Applications

Thermal Power: Boiler liquid level, steam pressure / temperature, flue gas oxygen content, feedwater flow

Oil and Gas: Wellhead pressure / temperature, compressor parameters, pipeline flow

Chemical / Metallurgy: Reactor parameters, distillation tower temperature / pressure, kiln temperature

Water Treatment: pH, conductivity, dissolved oxygen, liquid level / flow

IV. Differences from G02 (Brief)

1C31224G01: Standard type, -20℃~+60℃, isolated 1500V AC

1C31224G02: Enhanced type, -40℃~+70℃, isolated 2000V AC, higher anti-interference and reliability; can be directly replaced with G01
