Key features (high-density 5V AI positioning)

32-channel high density: single module 32-point differential input, saves slots and reduces costs

0–5V standard signal: directly connects to pressure / level / temperature transmitters, flow meters, valve position feedback

Differential + high common mode suppression: -80dB CMRR, strong resistance to on-site interference

TMR triple redundancy: three channels independent sampling + voting, SIL3 safety level, data reliable

Full coverage diagnosis: real-time detection of open circuits, short circuits, over-range, common mode abnormalities, panel LED + system alarm

Wide temperature + hot-swappable: suitable for harsh environments, online maintenance does not affect interlocks

Typical applications

SIS safety interlock: SIL3-level process parameter monitoring (pressure, temperature, level, flow)

Oil and gas / chemical: 32-point high-density signal acquisition, F&G fire and gas system analog quantities, containers / pipelines monitoring

Power / nuclear power: reactor parameters, boiler / turbine temperature pressure, critical equipment vibration / displacement

General safety monitoring: scenarios requiring SIL3, high density, differential anti-interference analog input with high density
